座标镗床主轴套筒是影响加工质量的关键部件。过去由于工艺和材料水平较低,一般磨损较快。如我厂 Z 450座标镗床使用十几年之后,主轴箱体孔与套筒的间隙已达0.016～0.018mm,并有拉伤。为此我们采取了如下修复措施,达到了规定的精度要求,现简要介绍如下。 1.主轴箱体孔的研磨修 Coordinate boring machine spindle sleeve is a key component of the quality of the processing. In the past due to lower levels of technology and materials, the general wear and tear faster. As I plant Z 450 standard boring machine to use more than ten years later, the gap between the spindle box hole and the sleeve has reached 0.016 ~ 0.018mm, and there is strain. To this end, we have taken the following repair measures to achieve the required accuracy requirements, are briefly introduced below. 1 spindle box hole grinding repair
