This series press machine use rigid rotating-key clutch, structure simple, easy operation and maintenance-free, driven by helical gear, stable, low impact.
J21-25 open inclinable punching machines are the domestic first batch of punching machine equipped with ball bearings, high resistance and low noise, instead of traditional sliding bearing (copper tile).
J21 open-type inclinable punching machine is unique in the industry, copper tile transmission gear.
Redesigned frame with high strength, transmission through ball bearing (low noise)
All J21-80T above punching machines: pneumatic double balancing cylinder structure balances the weight of slider and upper die to prevent shaking.
Can prevent gear colliding, minimizing noise, eliminating the gap between connecting rod and slider, reducing impact and wear of loaded parts
Prevent the slider from falling down and occurring accident in case of brake failure or connecting-rod breaking down
