在机床大修及维修过程中,特别是对于精密机床的修理,机床的滑动导轨,往往会产生重爬现象。这不仅使手轮驱动力和机床电功率增加,更严重的是破坏了导轨副的低速运动特性,影响微量进给、调整的准确性和机床的重复定位精度,从而影响被加工零件的尺寸精度,几何精度和光洁度。造成滑动导轨副重爬的机理十
Overhaul and maintenance of machine tools, especially for the repair of precision machine tools, sliding guide rails, tend to produce heavy climbing phenomenon. This not only increases the driving force of the handwheel and the power of the machine tool, but also seriously damages the low-speed movement characteristics of the guideway pair, affects the micro-feeding, the accuracy of the adjustment and the repeat positioning accuracy of the machine tool, thus affecting the dimensional accuracy of the machined part, Geometric accuracy and finish. Sliding guide rail caused by heavy climbing mechanism ten
