The guide rail as a guide is hardened steel, which is finely ground and placed on the mounting plane. Compared with the planar guide rail, the geometry of the cross section of the linear guide is more complicated than that of the flat guide. The reason for the complexity is that the groove needs to be machined on the guide rail to facilitate the movement of the sliding element. The shape and number of the groove depend on the machine tool to be completed. The function. For example: a rail system that withstands both linear forces and subversive moments, compared to rails that only accept linear forces. The design is very different. The new rail system allows the machine to achieve fast traverse speeds. At the same spindle speed, fast traverse is a linear guide. Linear guides, like flat guides, have two basic components; one for the fixed component and the other for the moving component. Since linear guides are standard components, for machine tool builders. The only thing left to do is to machine the parallelism of the plane of the mounting rail and the alignment rail. Of course, in order to ensure the accuracy of the machine tool, a small amount of scraping of the bed or column is essential, and in most cases, the installation is relatively simple.
