2. Cleaning bear teeth: Before grinding, thoroughly clean bear teeth with soapy water or detergent to remove dirt and grease on the surface.

3. Rough grinding: Stick it on the grinder with sandpaper or grinding wheel, and slowly rough grind the bearing tooth surface. You can start with coarse sandpaper and gradually transition to finer sandpaper until the ideal polishing effect is achieved.

4. Grinding: Use grinding fluid or abrasive, and use polishing cloth to cooperate with manual grinding. Dip some grinding fluid or abrasive, wipe the bearing tooth surface with polishing cloth with moderate force, and wipe it periodically until it reaches the required smoothness and luster.

5. Polishing: Use polishing paste and polishing cloth to smear polishing paste in a rotating or reciprocating way to polish the bearing tooth surface. This will further increase the luster and smoothness of bear teeth.
