Abstract

The invention discloses a multi-morphology combined micro-texture guide rail and a manufacturing method thereof, and relates to the technical field of machine tool guide rail surface treatment. The concave-convex alternated micro-textures are distributed on the surface of the guide rail; and the concave-convex alternated micro-textures are formed by a single-row micro-concave morphology and a single-row micro-convex morphology, the single-row micro-concave morphology and the single-row micro-convex morphology are arranged equal distance at intervals with each other; and a micro-groove which isconnected with a single micro-concave morphology in the length direction of the guide rail is machined in a micro-concave morphology array. According to the invention, the problem that a single texture composite morphology is difficult to be machined, oil is stored in the micro-concave, oil supply function in concave-convex composite morphology is difficult to play, and lubricating oil cannot flow are solved, so that the abrasion is better reduced, and crawling phenomenon of the machine tool or the guide rail are restrained.

Description

technical field [0001] The invention relates to a surface treatment technology for machine tool guide rails. Through laser micromachining technology, a micro-pits texture and a micro-protrusion texture are formed on the surface of the machine tool guide rails, and micro-grooves connecting micro-pits are distributed along the movement direction of the machine tool. The surface morphology of the groove particularly relates to the application of a surface micro-textured rail technology in the machine tool industry. technical background [0002] With the advancement of science and technology, the demand for complex precision parts has increased significantly, and precision machine tools play an important role in the machinery manufacturing industry. The guide rail of the machine tool is a key component of the whole machine, and its performance directly affects the machining accuracy and the life of the machine tool. Common defects of machine tool guide rails include large guide...
