为了提高定程磨削的尺寸精度,进一步扩大定程磨削在半自动、全自动内圆磨床上的应用范围,1973年我们在MBD215半自动内圆磨床上进行了一系列试验研究,取得了较为显著的成效。现将有关情况介绍如下: 一、误差分析及测定 定程磨削的尺寸精度是由进给机构的重复定位精度和砂轮修整 In order to improve the dimensional accuracy of the process grinding and further expand the range of application of the process grinding on the semi-automatic and fully automatic internal grinding machine, we made a series of experimental studies on the MBD215 semi-automatic internal grinding machine in 1973, The effectiveness of Now the situation is described below: First, the error analysis and determination of the size of the grinding process is the accuracy of the feed mechanism of the repeated positioning accuracy and grinding wheel dressing
