In view of the testing requirements of the motorized spindle in practical use,maintenance and repair,a test platform for different types of oil and gas lubrication spindle was built.The test platform consists of spindle auxiliary modules (spindle support fixed spindle unit,control unit,spindle oil and gas supply unit and somra knife unit) and electric spindle test module.Combined with the functions of data acquisition and processing based on VC programming,the test of temperature,vibration and noise for different types and diameters of oil and gas lubricated motorized spindle was realized,which provides experimental conditions for maintenance and repair of CNC motorized spindle.
