Short summary
The temperature distribution of a machine tool spindle is affected by its air gap. The more serious the air gap eccentricity is, the more uneven the temperature field of the spindle is. In the process of machine tool processing, the instability of the spindle temperature field leads to the decline of parts processing quality and unqualified products, which not only wastes materials, but also affects the processing process.
