Electric spindle is a new technology that has emerged in the field of CNC machining. Simply put, it combines the spindle and spindle motor. Looking back at the development history of the past decade, the demand for precision instruments is particularly huge. Electric spindle is the intermediate component of high-speed CNC machine tools, and its function directly determines the high-speed machining function, machining accuracy, and output power of the machine tool,Electric spindle maintenanceHow to operate? The electric spindle supply manufacturer tells you.

The operation of an electric spindle not only requires high rotational speed, but also high angular deceleration and acceleration, and quick stopping in the specified direction, which puts very strict requirements on its layout description, production, and control. At the same time, it also brings a series of technical problems such as electric spindle heat dissipation, smoothness, and fine control.

It is necessary to carry out electric spindle maintenance to properly handle these issues, in order to ensure stable and reliable high-speed operation of the spindle and complete efficient precision machining. As an intermediate component in mechanical processing, the electric spindle combines the machine tool spindle with the communication servo motor shaft, directly installing the stator and rotor of the spindle motor into the spindle assembly. Through precise dynamic balance calibration, it has excellent reverse accuracy and stability, forming a perfect high-speed spindle unit, also known as an embedded electric spindle, which does not use a gear transmission pair, thus completing the zero transmission of the machine tool spindle system. After being powered on, the rotor directly moves the main shaft.

Because the electric spindle is a high-speed precision component, timing protection for its maintenance is essential

1. The radial runout of the far end of the electric spindle (250 millimeters) is usually required to be 0.012 millimeters (12 micrometers), with two annual inspections;
   

2. The axial runout of the electric spindle is usually required to be 0.002 millimeters (2m), with two annual inspections;
   

3. The extension interval when loosening the cutting rod is 10.50.1 millimeters (taking HSK63 as an example), with four annual inspections;
   

4. The radial runout of the taper hole of the electric spindle is usually required to be 0.002 millimeters (2m), with two annual inspections;
