Sheet metal plate press brake with E21 NC system
Frequency converter controls the positioning of X,Y axis
Main motor：SIEMENS Germay
Valve：Bosch Rexroth Germany
Standard Press Brake; Hydraulic Plate Bending Machine
1. The design meets EU international standards. The fuselage eliminates internal stress by annealing and ensures higher precision and strength. All NC hydraulic plate bending machines are designed using SOLID WORKS 3D programming and made with enhanced ST44-1 quality steel with the latest technology;
2. The WC67K series torsion axis hydraulic plate press brake uses Chinese ESTUN NC control system to help you increase your productivity and keep the lowest cost and lower maintenance costs. High quality and repetitive bending is obtained by using synchronized cylinders and valves;
3. E21 system programming control system and inverter realize the accurate positioning function of X axis Y axis;
4. Cutting-edge frequency response hydraulic control technology, rigid upper beam runs on 8-point bearings with bending precision of +/-0.01 mm;
5. Optional V-axis compensation function, and select the appropriate mold to bend complex shape work pieces easily.
