Hydraulic Press Brake With E21 System

General Features

Overall welding the front workbench vertical plates and machine frame ensures there are no seam between vertical plates and bilateral wall plates.
Adopt Estun E21 controller cantilever referring to man-machine engineering design, with simple NC operation surface, improving the operational accuracy and comfortability.
Left and right safety fences are used to protect the worker’s safety.

Min Features:

The whole EU streamlined design, heat treatment rack, high rigidity worktable, optional mechanical crowning device, to achieve precision bending.
Hydraulic synchronous control and Estun NC programmable logic controller ensure accurate repeatability and ease use.
Integrated hydraulic system (Bosch Rexroth Germany) allows automatically switch to slow bends in a quick way.
X axis and Y axis realize accurate positioning function by frequency converter through NC E21 system programming control.
Cutting-edge frequency response hydraulic control technology, more stable machine tools, more reliable operation.
The best ratio of parameters, optimal core configuration ensure stable performance, more convenient operation.
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.
