Abstract: There is provided a machine tool comprising: a moving cover 4 that opens or closes a machining chamber M; a blowout unit including a blowout port 42 that releases gas so as to cover an opening region Op generated when the moving cover 4 is moved from a closed position toward an open position; and a control unit that changes an amount of the gas released from the blowout port 42 according to an opening degree L of the opening region Op.

Abstract: Provided is a machine tool comprising: a coolant release unit 20 that releases a coolant into a machining space M; a moving cover 4 that is movable between an open position where the machining space M is opened and a closed position where the machining space M is closed; and a servomotor 32 that moves the moving cover 4 to the open position or the closed position; and wherein a driving force of the servomotor 32 for moving the moving cover 4 in a direction of the closed position is changed according to a state of the coolant in the machining space M.
