低速高负荷的重型机床和定位精度高的精密机床工作台、滑座、溜板等直线往复运动机构,工作时往往存在着移动速度的不均匀性,这就是常说的“爬行”现象。机床出现爬行的原因,大多是由机床滑动导轨面之间的摩擦特性所引起。当以普通机械油作为导轨润滑用时,上、下导轨之间的静摩擦系数总是大于动摩擦系数,这就是产生机床爬行的主要原因之一。如果采用防爬性能好的导轨油或导轨-液压油,导轨面将
Low-speed high-load heavy-duty machine tools and high-precision positioning precision machine tool table, slide, slide and other linear reciprocating mechanism, often there is movement speed of non-uniformity, which is often said that the “crawling” phenomenon. Crawling causes of the machine, mostly caused by the friction between the sliding surface of the machine tool. When using ordinary machine oil as the guide rail lubrication, the static friction coefficient between the upper and lower guide rails is always greater than the dynamic friction coefficient, which is one of the main reasons for the machine crawling. If you use a good anti-climb performance rail oil or rail - hydraulic oil, rail surface will be
