To provide a machining apparatus which can implement most efficient machining depending on a material of a workpiece.
The machining apparatus for machining a workpiece is comprised of at least one of a heating means for heating the workpiece and a cooling means for cooling the same. For example, a heating and cooling means 8 for heating and cooling the workpiece is formed of a heat generating and absorbing circuit 81 including a Peltier device 815 built in a workpiece holding means 3. To operate the machining apparatus, direct current is applied to the Peltier device 815 to generate a heat generating phenomenon and a heat absorbing phenomenon, and therefore the workpiece is heated and cooled. Further the machining apparatus is comprised of a heat radiating means 9 for easing redundant heat generating action and heat absorbing action generated from the heat generating and absorbing circuit 81.
