Brake pad grinding apparatus and method

摘要

To provide a method of and an apparatus for grinding a brake pad in which inclined faces at both ends of the brake pad can be ground along a single route and no grinding limit quantity is generated whether the boundary lines are parallel with each other or not. The apparatus according to the present invention comprises: a fixing portion 11 for fixing a brake pad 3; a rotary whetstone 21 having a rotation axis parallel to a friction face 3a of the brake pad 3, a grinding face of which distance to the rotation axis increases gradually or in plurality of steps in one direction of the rotation axis, and another grinding face of which distance to the rotation axis decreases gradually or in plurality of steps in the one direction of the rotation axis; and a transporter 10 for moving one of the brake pad and the rotary whetstone in relation to each other in a intersecting direction to the rotation axis.
