3) J21S open-type inclinable punching machine is unique in the industry, copper tile transmission gear.
4) Redesigned frame with high strength, transmission through ball bearing (low noise)
5) All J21S-80T above punching machines: pneumatic double balancing cylinder structure balances the weight of slider and upper die to prevent shaking.
6)Hydraulic Metal Punching Machine Can prevent gear colliding, minimizing noise, eliminating the gap between connecting rod and slider, reducing impact and wear of loaded parts
7) Prevent the slider from falling down and occurring accident in case of brake failure or connecting-rod breaking down
