Crankshaft grinding equipment
MQ8260A is modified on the foundation of the Product MQ8260 and intended for use in the car, tractor, diesel engine functions and their repair stores to grind the journals and crankpins of crankshafts.
Three diverse operate speeds are available by generating use of the belts in the workhead. Cross chucks are used in the headstock and tailstock. Friction coupling is utilized in the headstock transmission chain for its effortless adjustment. Desk traverse is operated either by hand or by power. Wheelhead rapid method and withdrawal is effected through hydraulic means. The wheel spindle becoming of 80mm in diameter has good rigidity and toughness. Use is produced of roller ways for wheelhead movement. The bed ways and wheelhead are lubricated in an automated cycle by implies of the oil pump.
