一、前言在以磨削加工作为对机床导轨精加工手段时,为了满足某些机床导轨曲线中凸中凹的要求,往往采取下述几种方法:1)用预加负载的方法。就是在机床导轨精加工时,给予预加负载,以使导轨向所要求曲线的相反方向有一定的变形,母机按直线进行磨削,磨完后去掉预加负载,工件就呈现所要求的曲线形状。2)磨削时靠操作工人用手“赶刀”的方法。3)把 First, the preface In grinding as a tool for finishing the guide rail, in order to meet some of the guide rail curve concave convex requirements, often take the following methods: 1) with pre-load method. Is in the machine tool guide finishing, given pre-load, so that the required direction of the guide rail curve to a certain degree of deformation, the machine according to a straight line grinding, remove the pre-load after grinding, the workpiece on the required curve shape. 2) by grinding workers operating the hand “rush knife” approach. 3) Put
