Crankshaft grinding machine
MQ8260C is modified on the basis of the Product MQ8260A and intended for use in the automobiles tractors diesel motor works and their restore ships to grind the journals and crankpins of crankshafts.
A few distinct operate speeds are obtainable by generating use of the belts in the work head. The cover can be opened so that the belts can be modified conveniently. Cross swallow-tailed chucks are selectively employed in the headstock and tailstockFriction coupling is used in the headstock transmission chain for its straightforward adjustmentSingle layer table, with an oblique angle of 10 degree, longitudinal traverse can be operated either by hand or by power. Wheel head quick technique and withdrawal effected by hydraulic means can be digitally shown at a resolution of .005mmThe wheel spindle being of 80mm in diameter has great rigidity and strengthThe roller techniques are for wheel head movementThe mattress techniques and wheel head methods are lubricated in an automated cycle by implies of the oil pump. CZPT coat is adhered to the bed way. Air cushion can be used on the tailstock offering effortless adjustment. Crosswise motion of tailstock is effected
