Two AC servo motors control each hydraulic cylinder and realizea combination of
high accuracy & speed and environmental friendliness.
HYDRAULIC AC SERVO DRIVE
The cycle time has been greatly reduced with the servo motor and the hybrid hydraulic system combined.
This is the most energy efficient servo press that realizes high repeating accuracy.
It can be applied to a wide range of processing to support your bending works.
BENDING SUPPORT is available without any troublesome setups.
Clamp & Unclamp by Lever.
Bevel shot protocts punches from dropping.
Separate punches attached & removed up-and-down by Slide mechanism.
Bending angle is automatically adjusted by Laser Beam used and non-contacted type bending sensor.
It can be shortened set up time with adjustment of bending angle by no influence of material deference.
The target thickness range was expanded to maximum thickness 6mm compared to the conventional option.

Shimizu Kogyo Co., Ltd. installed PVS 8525 NET in September 2013. The following evaluations have been obtained from the operator.
(1) PVS 8525 was used by experienced workers after its installation, but because it is better operatability and easy to use, now we are leaving the operation to inexperienced operators.
(2)Since the oblique butting can be done with the 6 axis tilt mechanism, the range of the processing contents has expanded.
(3)Eye clamp makes the mold replacement easier, so the setup has been improved.
