JH21-80T CNC Pneumatic Punch Press Machine From China Factory

Fine configuration, the key parts like pneumatic components, electrical components, sealing parts, buttons, etc all use imported parts; the machine features fine steel plates welded body, tempering treatment (or vibration relief), shot blasting, rigidness, accuracy, and stability; the whole machine adopts PLC centralized control. The gas circuits use an imported safety dual valve, which can achieve jog, inch, single and continuous punching; the pneumatic dual balance cylinder, balanced sliding block and punch weight, which reduces impact and noise, eliminate the clearance between connecting rod and sliding block, reduce the impact and wear of the stress parts.

● The machine features fine steel plates welded machine body, tempering treatment (or vibration relief), shot blasting, rigidness, accuracy and stability.

● Vertical located crank shaft, compact structure; the crank shaft undergoes grinding treatment after high frequency quenching, which has a good smooth finish and rotates flexibly; lengthened rectangle hex guideway with a surface of bronze plate, which has high guide accuracy.

● Pneumatic dual balance cylinder, balanced sliding block and punch weight, which reduce impact and noise, eliminate the clearance between connecting rod and sliding block, reduce the impactand wear of the stress parts.

● The whole machine adopt PLC centralized control. The gas circuits adopt imported safety dualvavle, which can achieve jog, inch, single and continuous punching.

● The key parts such as sliding block, guideways, worktable plate, connecting rod, and are all castings made of resin sand, which improved the surface roughness 1-2 level, and improve the size accuracy 2-3 level.

● The 60T-level machines adopt the electrical control device to adjust the die height. Fine configuration, the key parts like pneumatic components, electrical components, sealing parts, buttons and etc all adopt imported parts.
