In order to ensure the accuracy of the machine tool, a small amount of scraping of the bed or column is essential. In most cases, the installation is relatively simple.??
The guide rail as the guide is hardened steel, which is placed on the installation plane after fine grinding. Compared with flat guide rails, the cross-sectional geometry of linear guide rails is more complicated than that of flat guide rails. The reason for the complexity is that grooves need to be machined on the guide rails to facilitate the movement of sliding elements. The shape and number of grooves depend on the machine tool to complete. Function. For example: a guide rail system that bears both linear force and subversive moment is compared with a guide rail that only bears linear force. The design is very different.??
???? There is no intermediate medium between the moving element and the fixed element of the linear guide, but a rolling steel ball. Because the rolling steel ball is suitable for high-speed motion, has a small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as the tool holder and carriage of the machine tool. The basic function of the fixed element (guide rail) of the linear guide system is like a bearing ring, and the bracket for mounting the steel ball is shaped like a "v". The bracket wraps the top and both sides of the rail. In order to support the working parts of the machine tool, a set of linear guide has at least four supports. Used to support large working parts, the number of brackets can be more than four.
