Disclosed is a motor spindle lubrication temperature controlling system of a high speed machine tool comprising a motor spindle, an oil transferring equipment, a gas transferring equipment, an oil and gas mixing valve, a recycling system and a waste oil recovery equipment. The oil transferring equipment and the gas transferring equipment are respectively connected with the input end of the oil and gas mixing valve while the output end of the oil and gas mixing valve is connected with the bearing of the motor spindle, and the lower part of which is connected with the waste oil recovery equipment. The recycling system is connected with a cooling duct of the motor spindle. The temperature controlling system has the advantages that the motor spindle can be well lubricated and cooled down in time through adding oil and gas lubrication and cooling water circulation to the motor spindle so as to prevent the motor spindle from excessive friction and quick temperature increase and maintain the motor spindle in optimum
