1. Main Features:

• 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
