Abstract
A system is provided with a laser beam source, a reflector mirror that is a reflecting member for reflecting a laser beam emitted from the laser beam source, a spindle motor that is a rotating and driving unit for rotating and driving the reflector mirror, and a f-&thgr; lens that is a converging unit for converging a laser beam reflected by the reflector mirror. The reflector mirror is rotated and driven under the condition that its normal line is mounted to be slanted to a rotary axis of a spindle motor. The optical axis of the reflector beam of the laser beam introduced into the reflector mirror is deflected so as to take a precession. A circular track is depicted on the surface of a workpiece to be machined by a beam spot converged by the f-&thgr; lens to perform the machining work.
