Features:
The crankshaft grinding machine is used in automobile, tractor, diesel engine works and their repair shops to grind the journals and crankpins of crankshaft, also used in large engineering machinery and diesel engines for ships to grind crankshaft.
1. 4 different work speeds are obtainable by making use of double-speed motor & the belts in work head.
2. Union chuck are used in the headstock and tailstock for adjusting eccentricity up to 120mm.
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. Wheel-head rapid approach and withdraw is effected by hydraulic device.
6. Rolling guideways are used on wheel-head and made by high quality material.
The wheel spindle being of 80mm in diameter has good rigidity and strength.
7. The bed ways & wheel-head ways are lubricated in automatic cycle by means of oil pump.
8. Plastic coated bed ways with less friction.
9. The digital display device can be optional.
