GERD WOLFF KANTO 200T CNC Electro-Hydraulic Press Brake
CNC axis accuracy
1) Machine sliders (Y1, Y2) – synchronisation precision:
The slider movement axes control the bending depth and bending angle. The system consists of the control unit, two glass scales (Y1, Y2) installed on the work table, electro-hydraulic proportional valves and an amplifier. A closed control loop detects and controls the relative position of the slide and table as well as the speed and position of the slide. This ensures the synchronisation of the slide and maintains the bending depth and angle with high precision.
Positioning accuracy: ±0.02 mm
Repeatability: ±0.02 mm
2) Machine backgauge (X axis):
The forward/backward movement of the X-axis controls the dimensions of the sheet metal cut. The stop bar is driven by a servo motor and moves the crossbeam via a ball screw and linear guide. Operation is stable and precise.
Positioning accuracy: ±0.10 mm
Repeatability: ±0.03 mm
3) Mechanical compensation system (V axis):
The pull plate of the mechanical compensation is moved by a motor so that the compensation points are formed in an arc shape. The points perfectly compensate for the elastic deformation of the work table and slide to ensure angular constancy and straightness of the workpiece. Position sensors and CNC control ensure precise regulation.
