我厂 M 6430型滚刀开刃磨床的整个磨头及滑板系统(重约278公斤),均背在床身侧面(如图1所示),共重心落在床身外面,对床身导轨产生了很大的力矩,因而造成上面矩形导轨压板比压很大,不仅加剧了接触面的磨损,同时也产生了爬行现象。为此我们在大修时,在原机床滑动导轨的基础上,增加 I plant M 6430 hob knife grinding machine and the entire head grinding system (weighing about 278 kg), are back in bed side (as shown in Figure 1), the total weight fell on the bed outside, the bed rails Resulting in a lot of torque, resulting in a rectangular rail pressure plate above a large pressure, not only exacerbated the contact surface wear and tear, but also had a crawling phenomenon. To this end, when we overhaul, on the basis of the original machine sliding guide, increase
