ABSTRACT:
A main body of a machine tool is covered with a cover. A ceiling portion of the cover that is situated over a spindle motor is provided with an opening portion. The cover is provided with hanging portions that hang down from the opening portion with a predetermined clearance from side surfaces of the spindle motor other than the rear surface. Air that is mixed with a misty cutting fluid in a space inside the cover is sucked in through a suction pipe by a mist collector. The outside air flows into the space inside the cover through the clearance. The outside air that passes through the clearance is driven to flow through vents by a built-in cooling fan of the spindle motor, thereby cooling the motor, and is then discharged to the outside. In consequence, the temperature in the space inside the cover can never be increased by heating of the spindle motor.
