Abstract

The invention discloses a preparation method of an oleophobic cutter with a micro-nano composite structure surface, and belongs to the technical field of manufacturing of mechanical cutting tools. A micro-nano composite structure can be machined on the surface of a cutter by using a laser processing technology, and is micron projections formed on the surface of the laser-processed cutter and nano particles on the micron projections; and a certain surface treatment is performed for the composite structure to form an oleophobic cutter surface with the micro-nano composite structure. Under the lubricating condition, because of lipophobicity of the cutter surface, cutting liquid can be supplied to a cutter-chip interface more quickly, the lubricating state of a cutting area can be improved, the friction force of the cutter-chip interface is reduced, the guarantee is provided for friction reduction and wear reduction of the cutter, the cutting temperature can be lowered, and the bonding phenomenon of the cutter surface is relieved; and the oleophobic cutter can be widely applied to cutting and high-speed cutting of difficult cutting materials (such as titanium alloys, ultrahigh-strength steel, austenitic stainless steel), so that the cutter durability and the workpiece surface quality can be greatly improved.

Description

technical field [0001] The invention relates to a preparation method of an oleophobic cutter with a micro-nano composite structure surface, which belongs to the technical field of mechanical cutting cutter manufacturing. Background technique [0002] In recent years, with the rapid development of my country's aerospace manufacturing industry, the use of titanium alloys has increased year by year, so the processing of titanium alloy parts has become more and more important. As a typical difficult-to-machine material, titanium alloy has a small tool-chip contact length, a large knife-chip interface friction coefficient, severe adhesive wear and diffusion wear, and high cutting temperature. High-speed cutting can improve the machinability of titanium alloys to a certain extent and reduce the difficulty of cutting titanium alloys. However, high-speed cutting also has some shortcomings. For example, the lubrication state of the knife-chip interface is mostly boundary lubrication ...
