PREF Group provides CNC and hydraulic press brake machine for high-precision sheet metal bending, our machines range from 30T to 12000T capacity and are widely used in steel fabrication and industrial manufacturing.
NC press brake machines provide stable and economical sheet metal bending solutions for small and medium fabrication workshops with simple operation and reliable performance.
Main Features:
A large floor-type boring and milling machine is used for integral machining of the press-brake frame.
The shaft body is made of forged material, with high rigidity and good elasticity, equipped with a fine-adjustment device, and weak eccentric-load resistance.
Users can customize tooling segments of 10, 15, 20, 30, 50, 100, and 300 cm.
ESTUN or DELEM brand CNC systems are available for users to choose.
Ball screws and linear guideways are used and driven by servo motors, enabling fast and accurate back-gauge positioning.
The stop-finger height adopts an integrated adjustment design and can be manually adjusted.
It improves tooling change speed and increases working efficiency.

The NC controller is designed for practical bending jobs where operators need stable control, simple programming, and fast daily operation. It can control the main bending movement and backgauge positioning, allowing common bending steps to be edited directly from the controller interface.
Depending on the selected configuration, the machine can be equipped with controller options such as Estun E310P, Delem DA41T, or Cybelec CT8. Touch screen operation, angle programming, X-axis control, and optional R-axis control can help improve setup efficiency for small-batch and medium-batch sheet metal production.
The hydraulic system provides the main bending force of the NC press brake. It supports rapid down movement, slow approach, working-speed bending, fast return, and emergency stop functions, giving the ram a stable and controlled movement cycle during operation.
High-quality hydraulic valves and reliable sealing components help the machine maintain pressure stability under rated load. A well-matched hydraulic system reduces leakage risk, supports continuous production, and helps keep bending performance consistent over long service periods.
The main motor is selected according to machine tonnage, working length, and local voltage requirements. A stable motor output supports the hydraulic pump and helps the machine maintain reliable bending force during repeated production cycles.
For different markets, motor power and voltage can be configured to match local electrical standards. This helps simplify installation, reduce adaptation work on site, and improve long-term maintenance convenience for the workshop.
The oil pump is an important part of the hydraulic drive system. A properly selected gear pump provides stable oil flow and pressure output, helping the press brake complete bending movements smoothly and reliably.
High-strength pump construction, low-noise design, and good resistance to oil contamination can improve service life and reduce maintenance frequency. For workshops
The backgauge positions the sheet before bending and has a direct influence on repeatability. The NC press brake can be equipped with a precise rear stop system, adjustable stop fingers, and a screw or ball-screw transmission structure according to the selected model.
For common bending work, a stable backgauge makes it easier to repeat flange dimensions and reduce manual measuring time. Optional backgauge upgrades can improve positioning accuracy and make the machine more suitable for repeated parts and batch production.
The electrical system should be configured for stable signal transmission, safe operation, and convenient maintenance. Key electrical components, wiring layout, overload protection, foot pedal control, and safety circuits must be matched with the machine specification and local requirements.
Reliable electrical parts help reduce interference, improve controller response, and support consistent machine operation in daily workshop conditions. Clear cabinet layout also makes inspection and maintenance easier for service teams.
Crowning compensation is used to reduce the influence of ram and table deflection during bending. For longer workpieces, the center of the machine can deform slightly under load, which may cause angle differences between the middle and both ends of the part.
Manual or mechanical crowning options help correct this deflection by adding compensation along the worktable. This improves angle consistency and is especially useful when processing long sheets or parts with higher straightness requirements.
Punches and dies determine the bending angle, inside radius, flange shape, and forming quality. The correct tooling selection should be based on material type, sheet thickness, bending length, V-opening, and the final part shape.
Standard tooling can cover many common bending jobs, while special tooling can be selected for boxes, narrow flanges, deep channels, or complex forming tasks. Tooling should be confirmed together with the machine model before production planning.
The torsion-sync bar is the core synchronization structure of an NC press brake. It mechanically links both sides of the ram so the left and right cylinders move in a coordinated way during bending.
This structure is simple, reliable, and cost-effective, making it suitable for general sheet metal bending applications. Compared with advanced electro-hydraulic synchronization, torsion-bar synchronization is easier
A servo-driven backgauge can improve positioning response and repeat accuracy compared with basic manual or stepper-driven systems. It is useful when the workshop needs faster model changeover, more repeatable flange dimensions, or more efficient batch processing.
When combined with a suitable NC controller, the servo motor helps the backgauge move to the programmed position more accurately, reducing manual adjustment time and improving the overall bending workflow.
