China M1020A Centerless Grinding Machine

Machine application:
The machine is used for mass-producing cylindrical parts, ring parts in the way of centerless through feeding. And it also can be used for grinding cone parts with taper less than 1∶20 and molding rotational parts in the way of centerless in-feeding.
Machine configuration & characteristics:
1. only reg. wheelhead feeding.
2. Single side supporting GW. spindle. Easy to change the wheel.
3. Multi-piece dynamic pressure bearing is used on GW. spindle.
4. Single side supporting RW. spindle. Easy to change the wheel.
5. Inner cone sliding bearing is used on the front of RW. spindle and rolling bearing on the rear side.
6. AC converter motor regulates RW. Speed steplessly.
7. In-feed mechanism is equipped.
