1, the workpiece with the tip or chuck clamping, pretext, tailstock motor synchronous drive, manual grinding.

2, table longitudinal movement with manual or motorized two kinds of rotation. Motor driven by a motor, for jumping profile or adjustment, only one speed.

3, according to user needs can be equipped with left and right cross chuck, maximum adjustable volume, the vertical direction is 110 mm, lateral 2.5 mm, the shift indexing simply rotate around the chuck.

4, wheel, bench, cooling pump, oil pump driven by a separate motor.

5, head, tail carriage motor are controlled by the inverter to achieve synchronous operation, reducing the deformation of the workpiece.

6, wheelhead rapid retreat is driven by hydraulic pressure.

7, moving machine table using plastic guide posts with the international advanced technology, the performance is more stable and reliable.

8, the table and the wheel hydraulic, electrical interlocking structure, in terms of adjustment due to operator error or grinding ensures safe operation.

Crankshaft grinding machine MQ8260

MQ8260A crankshaft grinding machine is intended for use in automobile, tractor and diesel engine repairing shops to regrind the crankpins and journals of crandshafts. Wheelhead rapid approach and withdrawal is hydraulically effected, the worktable is operated approached either by hand or by power. Power table traverse, either left or right, is momentily actuated by depressing and releasing the electric push button in connection with the desired direction. This arrangement facilitates table spacing for the grinding of the next journal or crankpin.

1.Four different work speeds are obtainable by making use of a double - speed motor and the belts in workhead.

2.Union chucks are used in the headstock and tailstock for adjusting eccentricity up to 120 mm.

3.Friction coupling is used in the headstock transmission chain for its easy adjustment.

4.Table longitudinal traverse is operated either by hand or by power.

5.Wheelhead rapid approach and withdrawal is effected by hydraulic means .

6.Rolling guideways are used on wheelhead and made by high quality material . The wheel spindle being of 80 mm in

diameter has good rigidity and strength.

7.Plastic coated bed ways with less friction.

8.The bed ways and wheelhead ways are lubricated in automatic cycle by means of oil pump.

9.The digital display device can be optional.
