机床导轨的修复工作,目前国内大多数的工厂在没有导轨磨床的情况下,只能采用人工刮研工艺。这是一种既费体力又费工时的方法。在实际使用中,由于机床加工短零件的数量要比长零件的数量多许多倍,而导轨的磨损一般又是与受力面的移动次数成正比的,因此磨损后的机床导轨运动曲线往往具有如图的中凹形状。而且多数情况下l_1≈(1/3)l,l_2≈(2/3)l,h一般在0.2～0.8mm间,随工件的技术要求而升降。本文就是介绍选择最少切削量的括研方法,供参考。机床的导轨面往往要求与其他不会磨损的加工面具有一定的不平行度或不垂直度,这样,在修复时导轨面以不磨损的面作基准,才是最少切削量的方法。否则,导轨面虽然切削量少了,但其他基准面还需括研,
Machine tool rail repair work, at present most of the factories in the absence of rail grinding machine, can only use manual scraping process. This is a labor-intensive and labor-intensive way. In actual use, because the number of machined short parts is many times longer than the number of long parts, and the wear of the guide rail is generally proportional to the movement times of the stressed surface, the worn guide curve of the machine tool often has As shown in the concave shape. And in most cases l_1 ≈ (1/3) l, l_2 ≈ (2/3) l, h is generally between 0.2 ~ 0.8mm, with the workpiece technical requirements and movements. This article is to introduce the choice of cutting the minimum amount of research methods, for reference. The guide rail surface of the machine tool usually requires some non-parallelism or non-perpendicularity with other non-worn work surfaces, so that the guide surface with no wear surface as a reference when repairing is the method with the least cutting amount. Otherwise, although the rail surface cutting less, but the other datum need to include research,
