200-ton Pneumatic metal sheet hole Power Press, China hole punching machine manufacturer

200-ton Pneumatic metal sheet hole Power Press, China hole punching machine manufacturer.

● 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.
