Crankshaft Grinder/crankshaft grinding machine

 1.Three different work speeds are obtainable by the use of the belts in the work head.The cover of headstock can be opened so that the belts can be changed conveniently.

2.Cross swallow-tailed chucks are used in the headstock and tailstock.3.Friction coupling is used in the headstock transmission chain for its easy adjustment.4.Singlelayer table,with an oblique angle of 10 degree,longitudinal traverse can be operated either by hand or by power.5.Wheel head rapid approach and withdrawal effected by hydraulic means can be digitally be digitally displayed at a resolution of 0.005mm.6.The wheel spindle of 80mm in diameter has good rigidity and strength.7.The roller ways are for wheelhead movement.8.The bed ways and wheelhead ways are lubricated in an automatic cycle by means of the oil pump.Plastic coat is adhered to the bed way.
