J21 Fixed Bolster Mechanical Press

Product Detail

FEATURES:

J21-80/J21-125/JB21-160 adopt rotating key clutch, which is easy to operate and convenient to maintain with stable action and low noise.

J21Z-125/JD21-160 adopt dry friction clutch, which can stop the slider at any place immediately, and can also achieve the inch, single and continuous punching operation. This is convenient to adjust the die position at any time, thus improve the machining precision. The whole machine adopts imported PLC centralized control system and equipped with safety dual valve and balance cylinder, which makes it work smoothly and reliably. It can also be equipped with photoelectric protection device, it is a safety type press machine.
