PROBLEM TO BE SOLVED: To provide a temperature control device of a working machine that is inexpensive, energy-saving and capable of eliminating a temperature difference between the temperature of a room with the working machine installed, and the temperature of a working area.SOLUTION: Whether an average value T5 is larger or smaller than both of a target temperature T1 in the working area and the air temperature T2 in the room is checked. In the case of YES, the routine proceeds to a step S8, and a cylinder 175 is driven to open a cover 173 and to open an opening for working 172. Then, internal air in the working area A is replaced with external air surrounding a numerically controlled lathe 1, and the temperature in the working area approaches the air temperature T2 in the room. In the case of NO, the cylinder 175 is driven to close the cover 173 and to close the opening for working 172. Then, replacement of the internal air in the working area A with the external air surrounding the numerically controlled lathe 1 is ended, and operation of the temperature control device is ended. |
