Continued to use of tool wear, spindle axial force will be increase, leading to bearing damage, but will also affect the accuracy and effectiveness of engraving.
刀具磨损后仍继续使用，会加大电主轴轴向力，导致轴承受损，而且还会影响雕刻的精度及效果。

Spindle bearing on the stability of operation in direct influence on the processing quality, once the spindle rotation precision decrease of the machine tool use value will be low.
主轴在轴承上运转的平稳性直接影响工件的加工质量，一旦主轴的旋转精度降低，则机床的使用价值就会降低。

SET UP: Typically, the process of changing the tooling on a production machine tool in order to produce a different bearing component part number.
