Plunge grinding machines may be used to surface finish high quality parts which must not touch each other during the finishing process. Typical parts are:
In a Rösler plunge finishing system, the parts are attached to a high-speed rotating spindle, which is then lowered into a work bowl filled with grinding or polishing media.
The spindle is not limited to rotational action. In addition, vertical oscillation and eccentric orbital movement can be used to enhance the grinding action.
