迄今在机床制造和修理中,凡滑动导轨,多用深刮存油、点多耐磨,以保持导轨精度的点刮法进行刮研。但用这种点刮法刮研机床滑动导轨,却存在一个严重的问题——在起动时手轮重和低速移动时出现爬行。由此还可能引起定位精度不准、微量进给不匀等现象,以及在检测、调试和精加工中出现某些不正常现象。这类问题产生的原因主要是同导轨的摩擦特性有
So far in the manufacture and repair of machine tools, where the sliding rails, multi-purpose deep scraping oil, more wear-resistant point to maintain the accuracy of the guide rail scraping scraping method. However, there is a serious problem with this point scraping method for scraping the sliding guide rail of the machine tool - the crawling occurs when the handwheel is heavy and the speed is low during starting. As a result, inaccuracies in the positioning accuracy, uneven feed of the micro feed, and some irregularities in inspection, adjustment and finishing may also occur. The main reason for this type of problem is the friction characteristics of the guide rail
