Machine tool

摘要

A machine tool is comprised of a tool rest (202) for supporting a plurality of tools, and a laser beam generating means (A) for generating laser beam. When installing a tool for cutting machining on the tool rest, cutting machining can be performed on a workpiece (W). When installing a tool (100) for emitting laser beam on the tool rest, a hardening can be performed on the workpiece (W). Only by change of a tool, both cutting machining and hardening can be performed.
