Abstract:
1. A work chamfering method using a work holding portion including a first surface and a second surface, the first surface of the work holding portion including a portion having a static friction coefficient greater than 0.1, the method comprising: a first step of holding a work with the work holding portion by contacting the first surface of the work holding portion with a first main surface of the work and by contacting the second surface of the work holding portion with a second main surface of the work; and a second step of chamfering the work by using a tool; wherein the work holding portion is adapted to rotate the work around a center of rotation; further wherein the first surface of the work holding portion contacts the first main surface of the work at at least two remote contacting locations on the first main surface, the second surface of the work holding portion contacts the second main surface of the work at at least two remote contacting locations on the second main surface; further wherein the center of rotation is between the contacting locations; further wherein the work is a substantially plate segment formed into a shape including a curved line, and further wherein said work is a segment of a ring.
