ある。However, in the conventional processing apparatus as shown in FIG. 2, the rotary cutting tool 12a is arranged parallel to the rotation center axis O 1 -O 1 of the work W as described above. Therefore, when machining the end surface, the inner circumference, or the outer peripheral surface of the work W, in any case, the rotary blade 12a comes into contact with the work W at the surface, so that a large cutting resistance is generated and the rotary blade 12a swings, End face of W,
It may not be possible to precisely cut the inner and outer peripheral surfaces.

精密かつ高速に加工することができない。Further, in the processing apparatus (see FIG. 3) having the fixed blade 13 such as a cutting tool in place of the rotary blade 12a, when the outer peripheral surface of the work W is processed, the fixed blade 13 does not rotate and only the work W is processed. Since it has a rotating structure, the only way to process the work W at a high speed is to rotate the work W at a high speed, and also to rotate the work W at a high speed while holding the work W which is not necessarily symmetrical to the rotation axis. In this case, since the rotation is disproportionate, the holding force is lost due to the centrifugal force of the disproportionately synthesized component during the rotation, the holding of the work W becomes unstable, and the work W cannot be processed precisely and at high speed.

Instead, it is only necessary to rotate the rotary blade at high speed.Especially, even if the rotary blade that is a dedicated part for rotation is rotated at high speed, the rotary axis is rotated at high speed while holding a workpiece that does not necessarily have a symmetrical shape. Compared with the case where the rotation is performed, there is no whirling due to imbalance during rotation, and the rotary blade is stably held, so that the rotary blade is stably held, so that the work can be processed precisely and at high speed.
