Primapress WE67K Tandem Series Press Brake Machine

Categories CNC Press Brake, Press Brake

European design with a streamlined appearance.
Internal stress in welded parts is relieved through tempering for excellent stability.
Sandblasted to remove rust and coated with anti-rust paint.
Equipped with a Spanish five-face machining center. All machining surfaces are completed in a single setup, ensuring excellent dimensional and positional accuracy.
The machine frame is designed to ensure long-term accuracy and reliable performance.
The frame, assembly surfaces, and connection holes are machined after welding, with up to 60 ft completed in a single pass.
Supplied with three front sheet supports and finished with Nippon polyurethane paint.

Upper-stroke bending design for low-noise operation and stable performance.
Y1 and Y2 parallelism tolerance: 0.01 mm.
Y1 and Y2 can be programmed independently, allowing operation under unbalanced loads and cone-shaped workpiece bending.
A programmable pressure-holding time at bottom dead center ensures high bending accuracy for various workpieces.
The ram can move upward at a slow speed, allowing convenient workpiece positioning and handling by the operator.
The universal upper tool mounting surface accommodates a wide range of tooling clamping requirements.

Advanced closed-loop electro-hydraulic synchronized servo control system.
Hydraulic system equipped with Rexroth (Germany) components and a Sumitomo (Japan) oil pump.
Imported linear scales, guiding system, positioning system, and hydraulic balancing system ensure high-precision machining of both full-length and eccentric workpieces.
A throat-mounted “C” frame compensation device directly measures the distance between the upper punch and lower die to improve bending accuracy.
All cylinder seals are imported from internationally recognized brands, ensuring excellent quality and long service life.
The hydraulic system features overload relief protection to prevent leakage, with an easily visible oil level indicator.
Designed for continuous operation under rated load, providing stable performance and high precision.

Advanced closed-loop electro-hydraulic synchronized servo control system.
Ideal for high-precision, multi-step bending applications.
The X-axis is driven by a digital AC servo motor through a ball screw and precision linear guide.
The back gauge features a rigid tank-type structure for excellent strength and positioning accuracy.
Two independently adjustable gauge fingers with dovetail guides ensure smooth operation and high precision.
Special finger-stop design extends the back gauge adjustment range.

Electrical components are imported or supplied by Sino-foreign joint ventures in compliance with international standards.
Reliable, safe, long-lasting, and highly resistant to electrical interference.
The electrical cabinet is equipped with a cooling unit to ensure stable system operation.
A movable single-pedal foot switch with an emergency stop function provides safe and convenient operation.

The lower worktable is equipped with an automatic crowning compensation unit.
Compensation values are automatically calculated and controlled by the CNC system to ensure consistent bending angles across the full working length.
The specially designed worktable effectively reduces lower die deflection and improves bending accuracy.
