China Mg1020 Centerless Grinding Machine

Machine application:
This machine is applicable for centerless through-feed grinding of cylindrical and conical parts with high requirements on geometrical precision and surface quality and centerless in-feed grinding of cone with conicity less than 1:20 and the formed rotational parts. This machine is applicable for mass production.
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 the RW. spindle.
6. AC converter motor regulates RW. Speed steplessly.
7. In-feed mechanism is equipped.
8. The cooling system is equipped with magnetic separator and paper filter.
