effect grinding force

Effective Flute Grinding Article Norton Abrasives

Lowering the wheel speed will have the adverse effect. Another method of lowering the force/grit is through abrasive concentration. Higher abrasive concentration adds more cutting points to the grinding process and would also provide better finishes and cause the wheel to act harder. Lowering the concentration will have the adverse effect.

Bruxism Wikipedia

Bruxism is excessive teeth grinding or jaw clenching. Some bruxism activity is rhythmic with bite force pulses of tenths of a second (like chewing), and some have longer bite force pulses of 1 to 30 seconds (clenching). Evidence for this comes from observations of the modifying effect of medications which alter dopamine release on
