Control Technology
The bending machine slider adopts the most advanced closed-loop electro-hydraulic servo control technology in synchronism.
The grating scale install on the both sides detects the position signal and feed back the signal to numerical control of oil input in oil cylinders to control the synchronous operation of slider.
Deflection Compensation of Worktable
Using deflection compensation device of worktable can make you obtain accurate deflection compensation in wroktable. The device consistes of two pieces of raised sheets with several bevels and they move comparatively to form ideal curve of raised position, I nthis way, the deflection compensation between worktable and slider can be changed as per the pressure and the pre-added raised quantity of this device is controlled by numerical control system, the bending force and relevant compensation value will be automatically confrimed after the related parameters are input into the numerical control system.
Back Gauge:
The back gauge is driven by imported AC servo motor and transmitted by precise ball bearing and screw. It has the straight line rolling guide rail guiding, The control is credible and precision is high.
