Descripción
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 after being equipped optional in-feed mechanisms.
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 RW. spindle.
6. AC converter motor regulates RW. Speed steplessly.
7. Customer can order optional mechanisms of in-feed mechanism to enhance machine performance.
