Punching machine supplier, JH21-45T punching machine sheet metal manufacturers.
●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 impacted wear of the steel 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 , guide ways , worktable plate , connecting rod , and are all castings made in 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.
