Product Description
Crankshaft grinding machine main features:
MQ8260A is modified on the base of the Model MQ8260 and intended for use in the automobile, tractor, diesel engine works and their repair shops to grind the journals and crankpins of crankshafts.
Three different work speeds are obtainable by making use of the belts in the workhead. Cross chucks are used in the headstock and tailstock. Friction coupling is used in the headstock transmission chain for its easy adjustment. Table traverse is operated either by hand or by power. Wheelhead rapid approach and withdrawal is effected through hydraulic means. The wheel spindle being of 80mm in diameter has good rigidity and strength. Use is made of roller ways for wheelhead movement. The bed ways and wheelhead are lubricated in an automatic cycle by means of the oil pump.
