Abstract

The invention relates to the field of surface treatment of machine tool guide rails, in particular to a composite micro-texture guide rail and a preparation method thereof. Aiming at the technical problem that the surface performance of a composite guide rail needs to be improved, the novel composite micro-texture guide rail is provided. According to the composite micro-texture guide rail, micro-texture grooves are formed in the contact surfaces of a fixed guide rail body and a sliding guide rail body, the micro-texture groove perpendicular to the sliding direction is machined on the surface of the fixed guide rail body, and can be used for storing lubricating oil and collecting grinding chips, the micro-texture groove parallel to the sliding direction is machined on the surface of the sliding guide rail body, due to the fact that the flow guiding and dynamic pressure effects of the lubricating oil are achieved, the formation of a lubricating oil film is facilitated, and then the effects of enhancing lubrication, reducing friction and improving the performance of the guide rail are achieved.

Description

technical field

[0001] The invention relates to the field of surface treatment of machine tool guide rails, in particular to a micro-textured guide rail and a preparation method thereof. Background technique

[0002] As the main guiding and supporting components of machine tools, guide rails are one of the most critical basic components. Their precision and performance play a very important role in the machining accuracy, production quality, and service life of machine tools. However, the characteristics of large variation range of load and motion speed and long running time require the contact surface of the guide rail to have good wear resistance and lubrication performance. However, due to the lack of complete liquid friction, ordinary sliding guides have large frictional resistance, easy to crawl at low speeds, large wear, low service life, and unstable motion accuracy. In order to improve the performance of sliding guide rails, the guide rails are often treated with pl...
