Abstract

The invention belongs to the surface treatment technology for machine tool guide rails, and particularly relates to a micro-nano composite texture guide rail and a preparation method thereof. The micro-nano composite texture guide rail comprises a fixed guide rail and a sliding guide rail, the fixed guide rail is located below the sliding guide rail, and the sliding guide rail can do reciprocatingmotion relative to the fixed guide rail. Multiple micro-texture grooves perpendicular to the sliding direction are formed in the surface, in contact with the sliding guide rail, of the fixed guide rail, and the micro-texture grooves are arranged evenly in a staggered manner. Correspondingly, multiple nano-texture grooves perpendicular to the sliding direction are formed in the surface, in contactwith the fixed guide rail, of the sliding guide rail, and the nano-texture grooves penetrate through the surface of the sliding guide rail. According to the micro-nano composite texture guide rail, the micro-texture grooves perpendicular to the sliding direction are formed in the fixed guide rail of the guide rail, lubricating oil can be stored, and grinding scraps can be collected; and the nano-texture grooves perpendicular to the sliding direction are formed in the sliding guide rail, forming of a lubricating oil film is facilitated, and therefore the functions of enhancing lubricating, reducing friction and improving the performance of the guide rail are achieved.

Description

technical field [0001] The invention relates to the surface treatment technology of machine tool guide rails, in particular to a micro-nano composite texture 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 in precision ultra-precision machine tools. Their accuracy 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. [0003] In order to improve the performanc...
