China M1080d 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 plunge in grinding.
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. Multi-piece sliding bearing is used on RW. spindle.
6. Subsection variable speed of RW. is realized by change gear.
7. Manual controlled plunge-cut mechanism is equipped.
