长期来,在机床的制造与修理中,机床导轨的刮研一般采用点刮法,这种方法有一定的优点,但也存在劳动强度大、生产效率低、导轨面接触少和磨损快等缺点。为此,我们从改进点刮法的刀花入手,选用一种以往用于修饰的方形刀花加以适当减深、变宽,以便使导轨面具有较多的接触面积,达到导轨副变轻的目的,从而形成了一种新的刮法——宽刮法。在多种带有重爬等故障的机床上应用,都取得良好的效果。解决了我厂不少普通及精密机 For a long time, in the manufacture and repair of machine tools, scraping and grinding of machine tool guide rails generally adopt point scraping method. This method has certain advantages, but also has the disadvantages of high labor intensity, low production efficiency, less contact with the guide rail surfaces and fast wear . To this end, we start from the point of shaving knife to start the process, the use of a selection of the former used to decorate the square knife flower appropriately reduced, widened to make the rail surface with more contact area, to rail lighter Purpose, thus forming a new scraping method - wide scraping method. In a variety of heavy machine with failure and other applications, have achieved good results. Solved many ordinary and precision machinery factory
