Features
1. The workhead of this crankshaft grinding machine takes advantage of belt, and the working speed can be set at 3 values.
2. Cross chucks can be applied by the headstock and tailstock. In addition, theheadstock transmission chain uses friction coupling, and it is convenient foroperation and adjustment.
3. The diameter of wheel spindle is 80mm, and the spindle has good rigidity andstrength.
4. Rolling guide is applied by the wheelhead,and the rapid movement of the wheelhead is controlled by the hydraulic device.
5. The working table moves longitudinally, and the movement can be achieved bypower or manual mode.
6. The lubrications of wheelhead guide rail and bedway arerealized by the automatic cycle process of oil pump.
