Characteristics
The crankshaft grinder model MQ8260C is modified on the foundation of the Design MQ8260A and meant for use in the automobiles, tractors diesel motor works and their repaire stores to grind the journals and crankpins of crankshaft.
@A few distinct function speeds are obtainable by creating use of the belts in the operate head. The protect can be opened so that the belts can be altered conveniently.
@Cross swallow-tailed chucks are selectively employed in the headstock and tailstock.
@Friction coupling is utilized in the headstock transmission chain for its simple adjustment.
@One layer desk, with an oblique angle of ten degree, longitudinal traverse can be operated both by hand or by energy.
@Wheel head fast strategy and withdrawal effeced by hydraulic signifies can be digitally exhibited at a resolution of .005mm.
@The wheel spindle getting of 80mm in diameter has excellent rigidity and toughness
@The roller ways are for wheel head movement
@The mattress methods and wheel head ways are lubricated in an automated cycle by signifies of the oil pump.
@CZPT coat is adhered to the bed way.
@Air cushion can be utilised on the tailstock offering easy adjustment. Crosswise movement of tailstock is effected.
