本文论述了钻镗类组合机床精度标准中关于主轴回转轴线与夹具导向孔轴线相对位置精度的检验方法问题,对采用等距度检验方法和重合度检验方法作了分析对比,结论是:按等距度来评价主轴回转轴线与导向孔相对位置精度欠佳;但按重合度的数据来评价却是较优的。因此,作为行业控制产品质量的标准,这两种检验方法并存是不适宜的。 This paper discusses the test method of the relative position accuracy of the spindle axis and the fixture guide hole axis in the precision standard of the boring and boring machine tools. By using the equidistance degree test method and the coincidence degree test method, it is concluded that: Distance to evaluate the spindle axis of rotation and the relative position of the guide hole poor accuracy; but according to the coincidence data to evaluate it is better. Therefore, as the industry control product quality standards, the coexistence of these two tests is not appropriate.
