4 Claims

1. A method for separating a first member and a second member joined to each other at a bonded part away from each other, comprising the steps of:

placing the first member and the second member on a worktable with the first member facing away from the worktable;

placing a clamp ring on the surface of the first member, the clamp ring having a contact surface abutting against the surface of the first member and a through hole extending through the contact surface such that the through hole of the clamp ring aligns with the bonded part;

plunging a separating rotating tool including a probe having a screw thread on a peripheral surface thereof into the surface of the first member through the through hole of the clamp ring, the screw thread being directed so as to lift material of at least a part of the bonded part away from the second member as a lifted part;

lifting the probe along with the clamp ring away from the surface of the first member; and

separating the first member and the second member away from each other,

wherein the bonded part extends from a start point to an end point along the surface of the first member, the method further comprising the step of moving the clamp ring and the probe along the bonded part from one of the ends thereof to the other after the step of plunging the rotating probe and before the step of lifting the probe so as to convert the bonded part into a lifted part, the contact surface of the clamp ring being provided with a groove extending from the through hole to an outer periphery of the contact surface and oriented to a trailing direction with respect to movement of the clamp ring.
