This composition makes it possible to obtain a magnetic bearing which is capable of sufficiently attenuating a bending natural frequency of a high-speed rotating body and supporting this rotating body with high rigidity even when a normal rotation frequency and a reverse rotation frequency of the high-speed rotating body vary.

The circuit outputs the correcting amount synchronously with the rotating position and processing point of the work. The adjustment device has the tool fixed thereto for finely moving the tool in a processing direction based on an output from the circuit. The fine adjustment device is secured to the XY table.
