本文论述了钻镗组合机床精度标准中关于主轴回转轴线和夹具导向孔(或样件孔)轴线相对位置精度的检验方法问题,主张将同轴度检验方法纳入标准,摈弃等距度检验方法。
In this paper, we discuss the testing method of accuracy of boring and boring machine tools in relation to the relative position accuracy of spindle axis and jig guide hole (or sample hole) axis, and advocate that the concentricity test method should be included in the standard and reject the equidistance test method.
