Grinding Wheel Motion and Force Analysis in ...
The grinding force is 1.84, 1.92, and 2.22 N at 135,000, 155,000, and 175,000 rpm rotational speed, respectively, when a 2.38 mm diameter burr is tested in a bovine bone sample with a 4 mm lumen. While orbiting around the lumen, the grinding wheel bounces on the wall of the plaque, leaving discrete grinding marks.
