CNC Crankshaft Disc Grinding Machine CSG 500 CNC / CSG 500x800 CNC - Welcome to Hmt MachineTools

Salient Features :

»	High precision 5-axes Crankshaft Grinding Machine that offers economic solution for grinding of crank pins and journals of crankshafts in automatic cycle.
»	Inprocess two jaw steady rest and gauge controls the finished size
»	Only loading/unloading and indexing for next pin set-up to be done manually.
»	Directly driven ball screws with AC servomotor for infeed axes.
»	Both ends fixed and pre-stretched precision ball screws driven by AC servomotors for reliability of positions.
»	Profile dressing along with end radius.
»	Infinitely variable speed for work head.
»	Rigid structure.
»	Wheel spindle runs in special high precision tilting pad type hydrodynamic bearing with independent continuous lubrication system.
»	Dual table with aerostatic lifting arrangement enable precise and easy taper setting (CSG 500 CNC).
»	Counter balancing device and chucking device mounted on work spindle. Work drive motor is de-energised for balancing of crankshaft easily.
Special Executions :
