Abstract

The invention relates to a preparation method of a super-hydrophobic bionic numerical control machining tool. The preparation method is characterized in that two-section type microstructures formed bymicro-protrusions and micro-grooves are arranged on the front tool surface and the rear tool surface of the tool, a sawtooth-shaped nanostructure is arranged at the position of the corner radius, hard particles are subjected to hypersonic flame spraying, and solid lubricant coatings are coated with the hard particles; the two-section type microstructures formed by the micro-protrusions and the micro-grooves are prepared on the front tool surface and the rear tool surface of the tool through the nanosecond laser machining technology, the contact area between the tool and cuttings is reduced, friction between the tool and the cuttings is relieved, and the hard abrasive particles are stored; meanwhile, in order to enable a tool nose to cut in a workpiece more gently without resistance, the sawtooth-shaped nanostructure with the intervals about 300-400 nm and the depths about 100-150 nm is machined at the position of the corner radius through the femtosecond laser machining technology; and then solid lubricant powder is coated with the hard particles through the hypersonic flame spraying technology, suspension liquid is prepared, the microstructure surface of the tool is coated with the suspension liquid, and the dual effects of superhydrophobicity and friction reduction are achieved.

Description

technical field

[0001] The invention belongs to the technical field of mechanical cutting tool manufacturing, and in particular relates to a method for preparing a superhydrophobic bionic numerical control machining tool. Background technique

[0002] Metal cutting processing is a key part of the machinery manufacturing industry, and its general trend of development is high-speed, high-efficiency, high-precision, high-flexibility, intelligence and green. The use of cutting fluid in cutting processing plays an important role in improving processing efficiency and improving the surface quality of the workpiece, but the production, use, treatment and discharge of cutting fluid have certain negative effects on the environment and operators; the birth of high-speed dry cutting technology is undoubtedly at the source On the one hand, the problem of negative impact of cutting fluid is solved, and tool performance has a decisive influence on cutting efficiency, precision and surface...
