目前大多数企业还没有专门的检测仪器可以对箱体孔的同轴度和国度进行精密测量,以确定这两项形状和位置误差的数值。尤其是当被测孔径较大、两孔距离较远的大、中箱体,更难测量。本文介绍一种临床的检测方法,可以对箱体孔的同轴度进行全数检查和圆度的抽样检查,并能达到较高的 At present, most enterprises do not have a special testing instrument can be box hole coaxiality and precision measurement to determine these two shape and position error values. Especially when the measured aperture is larger, the distance between the two holes, large box, more difficult to measure. This article describes a clinical test method that can check the concentricity of the box hole for full inspection and circularity for sample inspection and can achieve higher
