A control valve that is interposed in a pressurized air supply system that supplies pressurized air to an air turbine connected to a spindle and that adjusts the amount of pressurized air that is supplied to the air turbine, and a control valve that controls the rotation of the air turbine. An air spindle rotation speed control device comprising: a sensor that detects the number of rotations; and a control means that fully closes the control valve when the sensor detects that the air turbine has stopped during the opening operation of the control valve. . 2. The control means compares the actual rotation speed obtained from the sensor with the set rotation speed, and adjusts the opening degree of the control valve according to the comparison value, and when the set rotation speed exceeds zero rotation speed. 2. The air spindle rotation speed control device according to claim 1, wherein said control valve is fully closed when the actual rotation speed reaches zero rotation.
