40 Ton Small Hydraulic Press Brake uses the mold (punch and die to bend a cold metal sheet into a workpiece of various geometric cross-section shapes. It is a sheet metal forming machine designed for cold rolling sheet metal processing. It is widely used in sheet metal bending, such as automobile, aircraft manufacturing, light industry, shipbuilding, container, elevator, railway vehicles and other industries.

The 40 ton Press Brake Machines system is E21,and is equipped with a frequency converter and a ball screw to ensure the accuracy and speed of the machine.

The positioning of back gauge is more accurate.At the same time ,the system has 40 program programming ,each program up to 25 steps can be stores.The operator will get a powerful output to ensure that sensitive bending work can be completed perfectly.In addition, the equipment can be made according to individual requirements,so you can meet the functions required for specific sheet metal production needs.
