CNC Press Brake

Description

CNC press brake is an electro-hydraulic synchronized double-cylinder CNC bending machine. The bending principle is similar to the angle forming principle of common bending equipment. It can bend different workpieces according to different angles of moulds. The CNC system controls the electro-hydraulic ratio direction valve. CNC press brake can realize bending depth full closed-loop digital control through the grating feedback. CNC bending machine can simply be summed up as a bending machine that controls positioning system, block bending depth and automatic compensation for workbench deformation through CNC system. We also provide hydraulic and tandem press brakes.

Features

• CNC bending machine is equipped with computer system from Netherlands Delem Company, and imported grating, hydraulic system and servo motor.
• CNC press brake has good performance and strong unbalance loading capability.
• The electronic-hydraulic proportional servo synchronization makes arbitrary point control during stroke. The repeat accuracy can reach ± 0.01 and the parallelism is ± 0.02.
• CNC bending machine (CNC press brake) is featured with small geometric tolerance and high precision. When the rack eliminates stress, the whole machine finishes single clamping processing.
• The lower workbench adopts deflection compensation cylinder, the upper mould is equipped with deflection compensation agency or the lower workbench is installed with manual or automatic deflection compensation device.
• Slider stroke and back gauge are controlled by computer. The back gauge adopts ball screw and rolling guide with high repeat accuracy.
