E21 Hydraulic Torsion Bar Press Brake

Product Item: E21 Hydraulic Torsion Bar Press Brake

The hydraulic press brake is used to bend a variety of metal plates, including stainless steel plates, carbon steel plates, copper plates, aluminum plates, and aluminum alloy plates. With an exceptional strength and low cost, this hydraulic torsion bar press brake is widely used for the production of kitchenware, bathroom accessories, advertisement boards, light-fixtures and hardware, electric equipment and other metal manufacturing applications.

1.Main Features：

1.  The whole EU streamlined design, heat treatment rack, high rigidity worktable, optional mechanical crowning device, to achieve precision bending.

2.  Hydraulic synchronous control and Estun NC programmable logic controller ensure accurate repeatability and ease use.

3.  Integrated hydraulic system (Bosch Rexroth Germany) allows automatically switch to slow bends in a quick way.

4.  X axis and Y axis realize accurate positioning function by frequency converter through NC E21 system programming control.

5.  Cutting-edge frequency response hydraulic control technology, more stable machine tools, more reliable operation.

6.  The best ratio of parameters, optimal core configuration ensure stable performance, more convenient operation.

7.  WC67K standard single-axis back gauge system and single-axis bending angle system, you can choose to add the V-axis crowning function, and select the appropriate mold to bend complex shape workpieces easily.
