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.

Improved operability and design of the control panel

By changing a large-size numeric keypad, inputs without mistakes. And can check the input values quickly.
The size of buttons and words has been changed to the best size for touch input.
The screen layout has been desighned easy to see.
The buttons and icons has been desighned for easy to understand,and three dimensional.
By Gloria Blue design, it expresses calmness and Komatsu brand.

high repeatability

High depth repeating accuracy with the hydraulic system controlled by the servo motor.
The high rigidity frame design realizes stable bent angles with high load bending.
Equipping with the linear scale, accurate ram positioning is possible with little effect of widened side frames
Alignment accuracy improved with smooth offsets by increased wedges of the new angle controller.

Relationship between the time elapsed and bending accuracy

Improved Productivity and Enagy Saving

Quick ram response, high accuracy in repeating bottom positioning and environmental performance of saving energy have been made compatible.
Energy consumption has been extremely reduced with the high efficiency hybrid hydraulic system.
Interference area of the works has been made smaller with the optimized table width.

Relation of ram stroke and using electricity of each machines.

Greater Safty

Standardized double-action $ three-position foot pedal

Option(Setup improvement)

BENDING SUPPORT (option) helps you to hold large or heavy work during bending.*Only PVS1353-2/2253-2/2254-2

BENDING SUPPORT is available without any troublesome setups.

The tablet simulator (option) improves operability.

The tablet simulator (option) has bending CAM.It can be used in front of the machine and in other scene.
The tablet simulator (option) can create and modify bend data on inline and offline.
Sync mode：Can create and change bending data at the site. and can bend while checking 3D simulator.
independent mode：Removing the tablet simulator even while using the machine, can create and simulate bending data while viewing drawings at offices and other sites.

The tablet simulator

Operation panel equipped with tablet simulator

Easy operation for punch changing. It shortens time to charge punches.

Clamp & Unclamp by Lever.
Bevel shot protocts punches from dropping.
Separate punches attached & removed up-and-down by Slide mechanism.

Movie:Eye Clamp

Shortened time for the correction of bending angle.

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.

Movie:Bending Eye

Thickness range 6mm bending eye (option)

The target thickness range was expanded to maximum thickness 6mm compared to the conventional option.

User’s voice"PVS"

from Shimizu Kogyo Co., Ltd.

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.
