This crankshaft grinding machine is intended for using in automobiles, tractors,
diesel engines and their repair shops to grind journals and crankpins of crankshafts.
Features:
1) Four different work speeds are obtainable by making use of a double-speed
motor and the belts in the work head
2) Union chucks are used in the headstock and tailstock for an adjustable
eccentricity up to 120mm
3) Friction coupling is used in the headstock transmission chain for its easy
adjustment
4) Table traverse is operated either by hand or by power.
5) Rolling guide ways are used on wheel head, and made by high quality
material, the wheel spindle being of 80mm in diameter has good rigidity and
strength
6) The wheel spindle with 80mm diameter has good rigidity and strength
7) Plastic coated bed ways with less friction
8) The bed ways and wheel head ways are lubricated in automatic cycle by
means of oil pump
9) Additional synchronizer for headstock and tailstock: the gears of headstock
drive the tailstock to run in synchronism through the connecting spindle, thus
four different speeds are obtainable
10) The length of works is ranged from 800mm to 2,000mm
11) The digital display device can be optional
