When a fabrication business searches for a cnc press brake for sale, the buyer is not simply comparing machine photos and prices. The real decision is whether the machine can bend the right parts, hold the required accuracy, reduce setup time, survive daily production, and arrive with enough documentation and support for safe installation. This is especially important when the supplier is overseas, because the purchase process includes more variables than a domestic machine purchase: technical configuration, export packaging, shipping terms, voltage, certification documents, spare parts, installation guidance, remote service, and long-term communication.
At KRRASS, we evaluate a CNC press brake as a complete bending system rather than a single hydraulic machine. A stable press brake depends on the frame, cylinders, ram guidance, proportional hydraulic control, CNC controller, linear scales, backgauge, crowning system, tooling, clamping, safety devices, operator workflow, and service support. A strong frame without the right controller may waste time in setup. A high-tonnage machine without appropriate tooling may damage the tool or produce inconsistent bends. A low price without clear shipping and service responsibility may become expensive after the machine arrives.
This guide is written for purchasing managers, factory owners, production engineers, and international buyers who are comparing a CNC press brake from an overseas supplier. It explains what to check, what data to request, how to read a quotation, how to compare CNC controllers, and how to reduce risk before paying a deposit. It also includes practical tables that can be copied into an RFQ document or purchasing checklist.
For buyers who are still defining the basic machine size, the KRRASS Press Brake Configurator is a useful starting point because it asks for key parameters such as bending force, opening, box size height, axis configuration, controller, tooling, safety options, and voltage. Buyers who want to compare available machine types can also review the main KRRASS Press Brake page, where KRRASS lists CNC press brakes, NC press brakes, hydraulic press brakes, hybrid press brakes, and electric press brakes.

Why overseas evaluation must be more technical than price comparison
A CNC press brake is a capital machine. It influences quotation speed, product accuracy, labor efficiency, production planning, welding fit-up, assembly quality, delivery reliability, and long-term operating cost. When the supplier is overseas, the buyer cannot easily walk into the factory for a quick inspection after delivery. That means the evaluation must happen earlier, with better questions and better documentation.
Many online quotations look similar. They may show the same tonnage, the same bending length, and a similar machine body. However, two machines with the same nominal rating can perform very differently. The difference may be hidden in the frame design, cylinder synchronization, CNC axes, crowning method, hydraulic valves, electrical components, backgauge structure, tooling standard, software capability, and quality control process. A buyer should not ask only, “What is the price?” The better question is, “What production result does this configuration support, and what risk remains after installation?”
The evaluation should begin with the buyer’s own parts. A machine that is perfect for thin electrical cabinets may be too light for heavy structural brackets. A machine that is excellent for simple channels may not be the best choice for complex boxes with return flanges. A buyer bending long stainless steel panels needs a different discussion from a buyer bending short mild steel brackets. This is why KRRASS normally asks for drawings, material, thickness, bend length, flange size, tolerance, production volume, voltage, and layout constraints before recommending a model.
Overseas purchasing also requires stronger written confirmation. A domestic supplier may solve small misunderstandings in person. An overseas project depends on clear documents: specification sheet, proforma invoice, packing plan, tooling list, controller model, safety configuration, electrical drawings, hydraulic drawings, user manual, test video, and commissioning instructions. These documents should be part of the purchasing decision, not an afterthought.
Start from parts, not from machine size
A common mistake is to search for a standard machine size first, such as 100 ton by 3200 mm, then try to make all future parts fit that machine. That approach is risky. The correct method is to list the actual parts the factory will bend and then select the machine around those parts.
The buyer should prepare a small “bending family” table before contacting any supplier. It does not need to include every drawing in the factory, but it should include representative parts: the thickest material, the longest bend, the shortest flange, the deepest box, the most accurate angle, the most common production part, and the highest-volume part.
| Part family | Material and thickness | Longest bend | Shortest flange | Main evaluation point |
|---|---|---|---|---|
| Electrical cabinet panels | Mild steel 1.5-2.0 mm | 2500-3000 mm | 15-20 mm | Speed, repeatability, surface quality |
| Stainless kitchen equipment | Stainless steel 1.2-3.0 mm | 2000-3200 mm | 12-18 mm | Anti-marking, springback control, finish protection |
| HVAC ducts and covers | Galvanized sheet 0.8-2.0 mm | 2500-4000 mm | 10-25 mm | Long bends, light-gauge accuracy, easy setup |
| Structural brackets | Mild steel 4-8 mm | 500-2000 mm | 30-60 mm | Tonnage, tooling load, frame rigidity |
| Heavy machine guards | Mild steel 3-6 mm | 2500-3200 mm | 25-50 mm | Crowning, part support, operator handling |
| Box-type parts | Mild steel or stainless 1-4 mm | 300-1500 mm | Depends on design | Tooling clearance, gooseneck punch, collision risk |
This table quickly shows whether the buyer needs a light CNC press brake, a heavier hydraulic model, a hybrid press brake, extra backgauge axes, segmented tooling, front supports, a larger daylight, deeper throat, or a more advanced controller with collision simulation. It also helps the supplier avoid giving a generic quotation.
KRRASS product examples show how different configurations serve different production levels. The KRRASS MB8-80T2500 with DELEM DA-53T is a compact CNC press brake configuration with 800 kN bending pressure, 2500 mm bending length, Y1+Y2+X+R+W crowning axes, and a DA-53T controller. A buyer who needs more bending force can review the KRRASS 175T3200 DA-53T press brake, which lists 1750 kN bending pressure and 3200 mm bending length. For higher-end graphical control and multi-axis capability, the KRRASS DELEM DA66S CNC Press Brake lists 1100 kN, 3200 mm, and Y1+Y2+X1+X2+R1+R2+Z1+Z2+W crowning axes.
Understand the core specification: tonnage, length, daylight, stroke, throat, and axes
The most visible specification of a CNC press brake is tonnage, but tonnage alone does not define the machine. A practical quotation should describe the complete forming envelope and control configuration.
| Specification | What it means | Why it matters when buying overseas |
|---|---|---|
| Bending force | Maximum press capacity, often shown in tons or kN | Must match material, thickness, bend length, V-die opening, and tool rating |
| Bending length | Usable length across the bed | Must cover the longest part with enough handling space |
| Distance between columns | Open width between side frames | Affects whether long parts or deep parts can pass between frames |
| Daylight | Maximum open height between upper and lower beams | Important for tall tooling, box bending, and easy part removal |
| Stroke | Ram travel distance | Affects forming depth, tooling flexibility, and part handling |
| Throat depth | Distance from tooling centerline to frame | Important for wider panels and reverse bending |
| CNC axes | Controlled axes such as Y1, Y2, X, R, Z1, Z2, W | Determines positioning, setup speed, repeat work, and long-part compensation |
| Crowning | Bed compensation system | Helps maintain angle consistency along long bends |
| Controller | CNC interface and calculation system | Determines programming speed, simulation, memory, offline capability, and operator learning curve |
| Tooling standard | Punch and die interface | Affects compatibility with existing tools and future tooling supply |
| Safety system | Guards, light curtain, laser guard, safety PLC, emergency stop | Affects compliance, operator protection, and import acceptance |
A buyer should request these parameters in writing. The quotation should not only say “125T/3200 CNC press brake.” It should state the complete machine model, controller, axes, main motor power, voltage, tooling, crowning, safety device, and accessory list. Product pages such as the KRRASS PBS-110T2500 DA58T hybrid CNC press brake show how a specific configuration can be presented: 1100 kN bending pressure, 2500 mm bending length, Y1+Y2+X+R+W crowning, 8.7 kW main motor, 380 V 50 Hz operating voltage, and DELEM DA-58T controller.
When comparing overseas suppliers, check whether the stated tonnage is metric tons, US short tons, or kN. Also check whether bending length means total bed length or practical working length. For international purchasing, it is safer to use kN and mm in the final technical agreement because these values reduce interpretation errors.
Use bending force estimation as a screening tool
Bending force estimation is not a replacement for engineering review, but it is a valuable screening tool. It helps the buyer avoid two common errors: buying a machine that is too small for future parts, or buying a much larger machine than necessary and increasing cost, footprint, power demand, and tool load risk.
A simplified air-bending formula for mild steel is often expressed as:
P ≈ 650 × t² × L ÷ V
Where:
- P = bending force in kN
- t = material thickness in mm
- L = bending length in meters
- V = V-die opening in mm
This formula assumes ordinary air bending of mild steel in a typical reference range. Stainless steel, high-strength steel, aluminum, small internal radius requirements, bottoming, coining, and special tooling can change the result. The tool load rating and machine load distribution must also be checked. As a general purchasing habit, the buyer should discuss force with the supplier and keep a margin for real production rather than choosing a machine that only matches the theoretical number.
| Example material | Thickness | Bend length | V opening | Estimated force | Purchasing comment |
|---|---|---|---|---|---|
| Mild steel | 2 mm | 2.5 m | 16 mm | About 406 kN | Often within an 80T class machine, depending on other jobs |
| Mild steel | 4 mm | 3.2 m | 32 mm | About 1040 kN | Near a 110T class machine; margin should be reviewed |
| Mild steel | 6 mm | 3.2 m | 48 mm | About 1560 kN | Often points toward 160T or higher, depending on material and tolerance |
| Stainless steel | 4 mm | 3.2 m | 32 mm | Higher than mild steel | Needs correction factor and springback discussion |
| Aluminum | 3 mm | 3.0 m | 24 mm | Lower than mild steel in many cases | Radius and marking may matter more than force |
This table should be treated as an early planning tool. It does not certify a machine. The final decision should include the actual material grade, tensile strength, bend radius, tooling style, production volume, and tooling load capacity. If the buyer has high-strength steel or very narrow V-dies, the force requirement may rise sharply. If the buyer uses a larger V opening, required force may decrease, but the minimum flange length and bend radius may increase.
A good overseas supplier should be willing to explain this tradeoff clearly. If a supplier only says, “This machine can do it,” without asking material, thickness, V opening, bend length, and flange size, the buyer should slow down.
Match the V-die opening and minimum flange before choosing tonnage
Tonnage is closely connected to tooling. In air bending, a wider V opening usually reduces the required bending force, but it also increases the natural inside radius and the minimum flange that can be bent reliably. A narrower V opening may help a shorter flange, but it increases tonnage and tool stress. Therefore, the buyer should not evaluate tonnage separately from tooling.
For many mild steel applications, a common starting point is a V opening around 6 to 10 times the material thickness, with 8 times thickness often used as a practical reference. This is a rule of thumb, not a universal law. Stainless steel, aluminum, cosmetic surfaces, large radius requirements, acute bends, and special profiles may require another choice.
| Material thickness | Common first-check V opening | Practical meaning |
|---|---|---|
| 1.0 mm | 6-8 mm | Light sheet parts; attention to marking and handling |
| 2.0 mm | 12-16 mm | Cabinet panels, covers, general sheet metal |
| 3.0 mm | 18-24 mm | Medium sheet parts; common for enclosures and brackets |
| 4.0 mm | 24-32 mm | Higher force; check machine margin and tool rating |
| 6.0 mm | 40-50 mm | Heavy bending; check crowning and front support |
| 8.0 mm | 63-80 mm | Heavy-duty production; confirm frame, tooling, and load distribution |
Minimum flange length is also important. If the shortest flange in the drawing cannot sit safely on the die shoulders, the part may become unstable during bending. The buyer should send the shortest flange examples to the supplier and ask for tooling recommendations. For box parts, the discussion should include punch height, gooseneck clearance, sectionalized tooling, and collision risk.
This is where an experienced supplier adds value. KRRASS does not look only at nominal tonnage. We review the buyer’s parts, determine whether standard tooling is enough, and recommend options such as segmented punches, gooseneck punches, multi-V dies, quick clamps, front sheet supports, or customized tooling when the part geometry requires it.
CNC controller choice: simple operation or advanced simulation
The CNC controller is one of the most important differences between entry-level and advanced press brakes. It affects how quickly operators can program parts, how easily new operators can learn the machine, how bend sequences are calculated, whether crowning is controlled automatically, and whether complex parts can be simulated before production.
Delem is a common controller brand for CNC press brakes. Its official controller information is useful when evaluating a machine because it describes what each controller level is designed to do. The Delem DA-53T is a compact touch control for synchronized press brakes with a 10.1-inch screen, up to 4 axes, crowning control, tool/material/product library, USB interfacing, and Profile-53TL offline software. The Delem DA-58T adds 2D graphical touch programming, bend sequence calculation, and graphical simulation for efficient programming. The Delem DA-66S offers 2D programming, 3D machine representation, automatic bend sequence calculation, collision detection, a 24-inch high-resolution display, and Profile-S2D offline software. The Delem DA-69T is a high-end 2D/3D control with 3D visualization in simulation and production, a 17-inch display, and Profile-T3D offline software.
| Controller level | Typical fit | What buyers should check |
|---|---|---|
| Numerical or entry CNC | Simple bends, lower part variety, experienced operators | Axis count, memory, crowning support, ease of backup |
| 2D graphical CNC | Regular production, more part variety, faster setup needs | Bend sequence calculation, tool library, operator workflow |
| 3D graphical CNC | Complex parts, boxes, short runs, frequent setup changes | Collision detection, 3D machine representation, offline software |
| High-end 3D plus options | Demanding factories, sensor bending, multi-axis backgauge | Angle correction interface, backgauge axes, part support, data connectivity |
KRRASS configurations cover several of these levels. For example, the MB8-80T2500 DA-53T can fit buyers who want a practical CNC press brake with DA-53T control. The PBS-110T2500 DA-58T is suitable when buyers want 2D graphical programming and a more visual workflow. The DELEM DA66S CNC Press Brake supports more advanced multi-axis configuration and 3D representation. Buyers who need higher-end 3D programming can compare the KRRASS 135T hybrid press brake with DA-69T, which lists DA-69T control, 1350 kN bending pressure, 3200 mm bending length, and hybrid servo-driven configuration.
When buying from overseas, the controller discussion should also include language, units, software version, offline software availability, operator manuals, parameter backup, remote diagnosis, and training videos. A controller can be powerful, but if the operator cannot use it confidently, the factory will not receive the full productivity benefit.

Crowning is essential for long and accurate bending
Long bending creates a predictable mechanical challenge. When the press brake applies force, the ram and bed can deflect under load. This may cause the center of a long part to receive less effective forming depth than the ends, resulting in an angle variation along the bend line. KRRASS explains this issue in detail on the Crowning System page, where press brake deflection is described as ram and bed flex under load, especially in the middle of the machine.
Crowning compensates for this deflection. It may be manual, mechanical, hydraulic, or CNC-controlled depending on the machine configuration. For short brackets, crowning may be less critical. For long panels, stainless steel parts, high accuracy parts, and repeat production, it becomes a major factor.
| Crowning method | Best use case | Buyer evaluation point |
|---|---|---|
| Manual shimming | Low-volume, simple jobs, experienced operators | Slow adjustment; depends heavily on operator skill |
| Manual/mechanical crowning | General long bending with repeat setups | Ask how adjustment is made and whether scale values are repeatable |
| Hydraulic crowning | Production work with load compensation | Ask how the compensation is controlled and maintained |
| CNC crowning | Frequent job changes, higher accuracy expectations | Check whether controller calculates or stores compensation values |
For overseas purchasing, buyers should confirm whether crowning is included or optional. Some quotations may list a low price but omit crowning or include only basic manual adjustment. Others include W-axis CNC crowning as part of the CNC configuration. The difference affects both price and production stability.
A practical rule is simple: if the buyer regularly bends parts around 2500 mm, 3200 mm, 4000 mm, or longer, crowning should be discussed seriously. If the factory needs consistent angles across long parts, the supplier should explain the crowning system clearly and show how it is adjusted during test bending.
Backgauge axes and part positioning determine repeatability
The backgauge is not just a stop behind the tooling. It is the positioning system that helps operators produce repeatable flange dimensions. For simple parts, X-axis backgauge movement may be enough. For more complex parts, R-axis height adjustment, Z-axis finger positioning, X1/X2 independent movement, and multi-axis backgauge structures can reduce setup time and support angled or asymmetric parts.
| Axis configuration | Meaning | Practical benefit |
|---|---|---|
| X | Back/forth positioning | Basic flange depth control |
| R | Vertical movement | Useful for different die heights and step bends |
| Z1/Z2 | Left/right finger movement | Faster setup for different part widths and positions |
| X1/X2 | Independent backgauge depth control | Helps tapered or angled flanges |
| W | Crowning axis | Compensation for long bends |
| Y1/Y2 | Independent ram/cylinder control | Synchronization and angle control |
A buyer should compare not only the number of axes but also the mechanical quality of the backgauge. Ask about linear guides, ball screws, servo motors, positioning accuracy, repeatability, and whether the fingers are easy to adjust. For factories with many small batch jobs, faster backgauge setup can save more money than a small difference in machine price.
The KRRASS DA66S CNC Press Brake is an example of a higher-axis configuration, listing Y1+Y2+X1+X2+R1+R2+Z1+Z2+W crowning. This type of configuration is relevant when a buyer needs more positioning flexibility, reduced manual adjustment, and better support for varied parts.

Tooling, clamping, and accessories must be included in the RFQ
Many overseas quotations include a standard punch and die set, but “standard tooling” may not match the buyer’s parts. A buyer should never assume that included tooling can make all required products. Tooling determines the bend radius, flange feasibility, surface quality, clearance, collision risk, and setup speed.
The RFQ should specify whether the buyer needs segmented tooling, gooseneck punches, acute punches, hemming tools, multi-V dies, radius tooling, anti-marking film, urethane pads, or customized tools. It should also specify the tooling standard, such as European-style or American-style clamping, and whether the buyer has existing tools that must be compatible.
| Tooling item | Why it matters | What to ask the supplier |
|---|---|---|
| Standard punch and die | Covers basic 90-degree air bending | What angle, height, length, hardness, and load rating? |
| Segmented tooling | Needed for boxes and small parts | What segment sizes are included? |
| Gooseneck punch | Helps avoid collision with return flanges | What clearance does the punch provide? |
| Multi-V die | Flexible for different thicknesses | What V openings are included? |
| Quick clamping | Reduces tool change time | Manual, pneumatic, or hydraulic? |
| Tool cabinet | Protects tools and speeds setup | Is storage included or optional? |
| Front support | Helps long and heavy sheets | Fixed, sliding, or CNC-controlled support? |
If tooling is not checked carefully, the machine may arrive in good condition but still fail to produce the buyer’s most important parts. This is why the buyer should send drawings before ordering. KRRASS can review the part geometry and recommend tooling options together with the press brake model.
Safety and compliance should be part of the purchase decision
A CNC press brake creates high force at the point of operation. Safety is not an optional accessory. It affects operator protection, insurance review, import acceptance, installation responsibility, and long-term factory management.
For general machine guarding in the United States, 29 CFR 1910.212 states that one or more methods of machine guarding must protect operators and other employees from hazards such as point of operation hazards, ingoing nip points, rotating parts, flying chips, and sparks. OSHA’s machine guarding eTool gives examples such as barrier guards, light curtains, and two-hand operating devices. For press brakes specifically, ANSI B11.3-2022 is a machine-specific safety standard for power press brakes.
For buyers selling or operating machinery in Europe, the EU Machinery Regulation (EU) 2023/1230 is important because it sets health and safety requirements for machinery placed on the EU market and includes rules for CE marking. Machinery risk assessment principles are also supported by ISO 12100:2010, and safety-related control system design is addressed by ISO 13849-1:2023.
The buyer should not treat these references as paperwork only. They should influence the actual machine configuration.
| Safety item | Purchasing question | Why it matters |
|---|---|---|
| Emergency stop | How many E-stop points are installed? | Operators need reachable stop points |
| Light curtain or laser guard | Which brand and model? | Protects point of operation during bending |
| Safety PLC or safety relay | Is the safety circuit documented? | Important for compliance and maintenance |
| Side and rear guarding | What guards are included? | Reduces access to moving and hazardous areas |
| Foot pedal | Is it guarded and suitable for press brake use? | Prevents accidental activation |
| Electrical cabinet | Are components labeled and drawings provided? | Helps inspection, troubleshooting, and spare parts |
| CE documentation | Is CE declaration or related documentation available? | Important for EU market and some importers |
| Manuals | Are operation and maintenance manuals included in English? | Supports safe installation and training |
The exact required safety configuration depends on the country, application, and employer obligations. Buyers should involve their local safety professional, insurer, or compliance consultant when necessary. An overseas supplier can provide machine-level information and documents, but the final installation environment is controlled by the buyer.
Hydraulic, hybrid, or electric: compare total value, not only purchase price
Many buyers searching for a cnc press brake for sale begin with hydraulic machines because they are widely used, cost-effective, powerful, and familiar to operators. However, hybrid and electric press brakes are increasingly attractive for factories that value energy efficiency, lower noise, faster response, and more precise control in certain applications.
| Machine type | Strengths | Buyer considerations |
|---|---|---|
| Hydraulic CNC press brake | Strong force, mature technology, broad capacity range | Oil maintenance, hydraulic system quality, proportional valve control |
| Hybrid CNC press brake | Better energy performance, servo-hydraulic efficiency, smoother response | Higher initial cost, component availability, service knowledge |
| Electric press brake | Fast, clean, efficient for suitable tonnage ranges | Usually more limited in heavy tonnage; application must be checked |
| NC hydraulic press brake | Lower price, simple operation, suitable for less complex work | Less automation, lower positioning flexibility, more operator dependence |
A buyer should compare total value. If a factory runs short shifts and bends simple parts, a well-configured hydraulic press brake may be the best investment. If a factory runs frequent job changes with strict accuracy requirements, a higher-level CNC or hybrid machine may reduce labor and setup time. If energy consumption, clean operation, and high speed matter more than maximum heavy bending capacity, an electric solution may be worth discussing.
KRRASS offers different machine categories so buyers can choose based on production requirements rather than being forced into one technology. The key is to match the forming problem: material, thickness, length, accuracy, production volume, operator skill, energy strategy, and budget.
Supplier evaluation: what to verify before paying the deposit
A professional overseas supplier should be able to provide more than a product photo and a price. The buyer should verify technical capability, communication quality, documentation, export experience, inspection process, spare parts support, and after-sales service.
| Evaluation area | Low-risk sign | Warning sign |
|---|---|---|
| Technical discussion | Supplier asks for drawings, material, thickness, voltage, and production needs | Supplier pushes one model without asking about parts |
| Quotation | Includes full specification, controller, axes, tooling, safety, warranty, payment, delivery term | Only gives a short model name and price |
| Documentation | Can provide manuals, drawings, packing list, inspection video, and maintenance guide | Documentation is vague or unavailable |
| Quality control | Offers test bending, machine photos, factory acceptance video, and parameter confirmation | Refuses to show machine testing before shipment |
| Export experience | Understands packing, container loading, Incoterms, HS code, and shipping documents | Cannot explain freight terms clearly |
| Service | Provides remote support, spare parts list, and response process | Says “no problem” but has no support workflow |
| Communication | Answers technical questions consistently | Gives contradictory answers or avoids details |
The buyer should also verify whether the supplier can support the local voltage and frequency. Many KRRASS models list operating voltage such as 380 V 50 Hz on product pages, but overseas buyers may need 220 V, 380 V, 415 V, 440 V, 480 V, 50 Hz, or 60 Hz depending on the country. This must be confirmed before manufacturing.
Factory acceptance testing before shipment
For overseas purchasing, factory acceptance testing is the buyer’s best opportunity to confirm the machine before it enters the shipping process. The test does not need to be complicated, but it should be structured.
A practical FAT plan may include:
- Visual inspection of machine body, paint, nameplate, cabinet, tooling, and accessories.
- Power-on test of controller, emergency stop, safety devices, backgauge movement, crowning, and hydraulic system.
- Axis homing and positioning test.
- Test bending using agreed material thickness and length.
- Angle check at left, center, and right positions for long bending.
- Repeat bending of the same part to check consistency.
- Verification of included tooling and accessory list.
- Confirmation of voltage, language, units, and controller backup.
- Packing inspection before crate closure.
- Loading photos or videos if requested.
| FAT item | Suggested evidence | Why it helps |
|---|---|---|
| Controller model | Photo/video of controller screen and nameplate | Confirms the quoted controller is installed |
| Axis movement | Video showing X, R, Z, W, Y1/Y2 movement | Confirms actual axis configuration |
| Safety device | Video testing E-stop and guard response | Confirms basic safety function before shipment |
| Test bend | Video and measurement photo | Confirms bending result under agreed conditions |
| Long bend angle | Left/center/right angle photos | Confirms crowning and machine setup |
| Packing | Photos of waterproof film, rust protection, crate, and fixing | Reduces shipping damage risk |
If the buyer cannot visit the factory, video inspection is still valuable. The buyer can request a live video call or recorded FAT. The test should use clear measurement methods. For example, if the buyer wants long-part accuracy, the supplier should measure angles at both ends and the center, not only show one small sample.
International trade terms, shipment, and documents
The technical machine is only one part of an overseas purchase. The buyer also needs clear shipping responsibility. The International Chamber of Commerce explains that Incoterms rules are used in international and domestic contracts to clarify tasks, costs, and risks in delivery of goods, and Incoterms 2020 is the current version that entered into force on 1 January 2020.
The buyer should never accept a quotation that says only “shipping included” without naming the Incoterms rule, named place, and version. A correct term should look like “FOB Shanghai Incoterms 2020,” “CIF Port of Long Beach Incoterms 2020,” or “DAP buyer’s factory address Incoterms 2020.”
| Term often used in machinery trade | What buyers should clarify |
|---|---|
| EXW factory | Buyer normally handles pickup, export, freight, insurance, import, and delivery; can be difficult for inexperienced importers |
| FOB port | Seller delivers and loads goods on vessel at named port; buyer handles ocean freight, insurance if desired, import, and inland delivery |
| CIF destination port | Seller arranges ocean freight and insurance to destination port; buyer handles import and inland delivery |
| DAP buyer location | Seller arranges transport to named destination, but buyer usually handles import duties and taxes |
| DDP buyer location | Seller handles delivery and import duties; practical feasibility depends on country, tax registration, and customs arrangements |
The shipping document package usually includes commercial invoice, packing list, bill of lading or sea waybill, certificate of origin if required, insurance certificate when applicable, and machine documents. The buyer should also ask for HS code, gross weight, net weight, packing dimensions, and container loading plan. KRRASS product pages list HS codes on many machines, such as HS Code 8462299000 for several press brake configurations, but the buyer should still confirm the final code with the freight forwarder or customs broker in the destination country.
Because a press brake is heavy equipment, packing matters. The machine should be protected against moisture, rust, impact, vibration, and movement inside the container. The buyer should ask whether the machine will be wrapped, bolted to a base, protected with anti-rust oil, and fixed properly for sea transport.
Landed cost: compare the real cost, not only the machine price
A low machine price can become expensive if it excludes critical items. The buyer should calculate landed cost before choosing a supplier.
| Cost item | Usually included? | Buyer note |
|---|---|---|
| Machine base price | Yes | Confirm exact model and configuration |
| Controller upgrade | Sometimes optional | DA-53T, DA-58T, DA-66S, DA-69T affect price and capability |
| Crowning | Sometimes optional | Essential for long accurate bending |
| Tooling | Basic set often included | Confirm segment size, V openings, and load rating |
| Safety device | Varies by market | Confirm local requirements before ordering |
| Quick clamping | Often optional | Useful for frequent tool changes |
| Front support | Often optional | Useful for long or heavy sheets |
| Spare parts | Sometimes optional | Include filters, seals, relays, foot switch, tools, and consumables as needed |
| Export packing | Usually included in export quotation | Confirm seaworthy packing standard |
| Ocean freight | Depends on Incoterms | Check market rate and destination charges |
| Import duty and tax | Usually buyer responsibility | Confirm with customs broker |
| Inland transport | Usually buyer responsibility unless DAP/DDP | Press brake may need forklift, crane, or rigging |
| Installation and training | Varies | Remote support, local service, or engineer visit should be clarified |
| Foundation and power | Buyer side | Prepare floor load, power supply, air if needed, and oil requirements |
A fair comparison requires equal configuration. If Supplier A includes CNC crowning, laser safety, quick clamps, segmented tooling, and spare parts, while Supplier B quotes only the bare machine, Supplier B may look cheaper but be less complete. The buyer should normalize the quotation line by line.
Installation planning after arrival
A CNC press brake is not ready for production simply because it arrives at the factory. The buyer should prepare the installation site before shipment arrives.
Important preparation items include floor strength, unloading route, crane or forklift capacity, machine footprint, electrical power, grounding, hydraulic oil, temperature, humidity, operator space, tool storage, and safety perimeter. The buyer should check the machine dimensions and weight in advance. Some KRRASS pages list dimensions; for example, the MB8-80T2500 DA-53T page lists machine dimensions of 3220 mm × 1780 mm × 2650 mm, while the DA66S 110T3200 configuration lists 4030 mm × 1780 mm × 2680 mm. These values help the buyer plan unloading and placement, though the final order drawing should always be used for installation.
| Installation item | Buyer action before arrival |
|---|---|
| Foundation and floor | Confirm floor capacity and flatness; prepare anchors if required |
| Unloading equipment | Arrange crane, forklift, rigging company, and safe lifting path |
| Power supply | Confirm voltage, frequency, phase, breaker size, and grounding |
| Hydraulic oil | Confirm oil type and quantity if not shipped with oil |
| Environment | Keep machine away from excessive dust, water, corrosive vapor, and unstable temperature |
| Operator training | Prepare operators to learn controller, tooling setup, safety, and maintenance |
| Spare parts storage | Store consumables and electrical parts in dry labeled location |
| Documentation | Keep manual, drawings, parameters, and videos accessible to maintenance team |
The installation plan should also include first production validation. After leveling and commissioning, the buyer should bend sample parts from actual production drawings. This confirms not only that the machine runs, but that it fits the buyer’s real process.
After-sales support and spare parts are part of the machine value
A CNC press brake is expected to work for many years. The buyer should evaluate service support before signing the order. Overseas after-sales service depends on clear communication and practical spare parts planning.
The buyer should ask:
- What is the warranty period?
- Which parts are covered and which are consumables?
- How does the supplier provide remote support?
- Are wiring diagrams, hydraulic diagrams, and parameter backup included?
- What spare parts should be purchased with the machine?
- How quickly can replacement parts be shipped?
- Can the supplier provide video guidance for troubleshooting?
- Is local dealer support available in the buyer’s region?
- Are controller manuals and software backups provided?
- How are safety devices and CNC parameters protected from accidental changes?
KRRASS states on its website that it supplies a broad range of sheet metal equipment, including CNC press brakes, fiber laser cutting machines, hydraulic shearing machines, plate rolling machines, and ironworkers. Buyers who plan a broader factory upgrade can also review related equipment such as the KRRASS QC11K hydraulic guillotine shearing machine, the KRRASS 3000W fiber laser cutting machine, and the KRRASS ironworker machine. A supplier that understands the cutting, shearing, punching, and bending workflow can give more complete production advice than a supplier selling only one machine category.
A practical scoring model for comparing overseas quotations
When several suppliers provide quotations, the buyer can use a weighted scoring table. This prevents the decision from being dominated by the lowest price.
| Evaluation factor | Weight | Supplier A | Supplier B | Supplier C |
|---|---|---|---|---|
| Correct tonnage and bending length | 15% | |||
| Controller and axis configuration | 15% | |||
| Crowning and long-bend accuracy plan | 10% | |||
| Tooling suitability | 10% | |||
| Safety configuration and documents | 10% | |||
| Supplier technical communication | 10% | |||
| FAT and inspection support | 8% | |||
| Packing and shipping clarity | 7% | |||
| Warranty and spare parts support | 10% | |||
| Total landed cost | 5% | |||
| Total | 100% |
This model intentionally gives only 5% to total landed cost. That does not mean price is unimportant. It means price should be evaluated after the technical risk is controlled. A machine that fails to produce the required parts is expensive at any price.
The buyer can score each supplier from 1 to 5 in each category, multiply by weight, and then compare. A supplier with a slightly higher price may be the better choice if it provides the right controller, crowning, tooling, safety package, and after-sales support.
Red flags when searching online for a cnc press brake for sale
Online search results can be useful, but the buyer should watch for warning signs.
A supplier may be risky if it cannot provide a full specification sheet, avoids questions about tooling, does not ask for part drawings, cannot explain voltage conversion, gives inconsistent machine dimensions, refuses test videos, uses only generic machine photos, or cannot provide a clear packing list. A very low price may indicate missing options, lighter structure, lower component quality, weak service, or incomplete documentation.
Another red flag is overpromising. No press brake can bend every material, thickness, length, and part shape with one standard tool set. A professional supplier should explain limitations. For example, a part may require a larger V opening, but the drawing may also require a short flange. A deep box may need gooseneck tooling, but the return flange may still collide with the punch. A long stainless panel may require crowning and springback correction. These are normal engineering discussions, not problems to hide.
The buyer should also be careful with unclear certifications. CE marking, safety standards, and import requirements are not the same in every country. The supplier should state what documents are included, and the buyer should confirm local obligations. For the United States, OSHA machine guarding responsibilities apply to employers using the machine. For the European market, CE-related documentation and the machinery regulatory framework must be considered. For other regions, local rules and insurance requirements may apply.

What information to send KRRASS for an accurate recommendation
To recommend the right CNC press brake, KRRASS needs enough production information. A short message saying “Please quote 100T 3200 CNC press brake” is possible, but it may not produce the best configuration. A better RFQ includes:
- Material type: mild steel, stainless steel, aluminum, galvanized steel, high-strength steel, or other material.
- Material thickness range: minimum, common, and maximum thickness.
- Longest bending length.
- Shortest flange.
- Required inside radius.
- Typical bend angle and tolerance.
- Part drawings or photos.
- Annual or monthly production volume.
- Batch size and frequency of tool changes.
- Whether parts are cosmetic and require anti-marking protection.
- Whether the factory has existing tooling.
- Required controller level.
- Preferred CNC axes.
- Local voltage and frequency.
- Safety requirements or market destination.
- Preferred trade term and destination port or address.
- Installation schedule and service expectations.
With this information, KRRASS can recommend a configuration that balances price, performance, productivity, and long-term usability. The result may be a standard model, a customized configuration, a tooling package, or a suggestion to choose a different controller or crowning system.
Recommended purchasing workflow
The safest overseas purchasing process is structured and documented.
| Step | Buyer action | Output |
|---|---|---|
| 1 | Collect representative part drawings and production requirements | Bending requirement list |
| 2 | Estimate tonnage and tooling needs | Initial capacity range |
| 3 | Contact supplier with a complete RFQ | Technical quotation |
| 4 | Compare machine configuration, not only price | Supplier comparison table |
| 5 | Confirm controller, axes, crowning, tooling, safety, voltage, and accessories | Final technical agreement |
| 6 | Confirm Incoterms, payment terms, packing, shipment, and documents | Commercial agreement |
| 7 | Review drawing and production schedule | Order confirmation |
| 8 | Perform FAT by visit, live video, or recorded inspection | Pre-shipment approval |
| 9 | Confirm packing and loading | Shipping release |
| 10 | Prepare installation site before arrival | Smooth commissioning |
| 11 | Train operators and validate real parts | Production handover |
| 12 | Maintain parameters, spare parts, and service communication | Long-term reliability |
This workflow reduces misunderstanding. It also protects both sides because the supplier knows exactly what the buyer expects, and the buyer knows what the supplier will deliver.
