I. Structural composition of  electric spindle The electric spindle is a new technology that combines the machine tool spindle and the spindle motor in the field of CNC machine tools in recent years. The main drive system of high-speed CNC machine tools eliminates the belt drive and gear drive. The main shaft of the machine tool is directly driven by the built-in motor, which shortens the length of the main drive chain of the machine tool to zero and realizes the "zero drive" of the machine tool. This type of transmission structure intergrating spindle motor and machine tool spindle, which makes the spindle components relatively independent from the drive system and overall structure of machine tool, so it can be made into a "spindle unit", commonly known as electric spindle or Motor Spindle. The electric spindle is a set of components, which includes the electric spindle itself and its accessories: electric spindle, frequency conversion device, oil mist lubric...
