PROBLEM TO BE SOLVED: To provide a machining device which is particularly fit for machining of a difficult-to-machine material, and to provide a machining method which can machine a workpiece with high accuracy and high quality by using the machining device. SOLUTION: The machining device has both an infrared heating furnace 7 which heats the workpiece W set in the machining device to a predetermined temperature below a fusing temperature, and a tool cooling means such as a vaporization heat cooling device 10 for cooling a ball end mill T which machines the workpiece W, and machines the workpiece W which is softened by heating, by the ball end mill T which is hardened by cooling. According to the machining method, machining is carried out by taking into consideration a thermal deformation quantity of the workpiece by heating, in addition to a shape data of the workpiece.
