Abstract

The invention relates to a method for inhibiting chemical wear of a diamond cutter on an oxidized metal surface. The method comprises the following steps that when the diamond cutter is subjected to ultra-precision machining, the oxidation capacity of an environment medium in a machining area is increased through a multi-energy field auxiliary technology, and an oxidation film is formed on the surface of the machining area. According to the multi-energy-field auxiliary technology, chemical energy or combined energy of optical energy and chemical energy is applied to the periphery of the diamond cutter to increase the forming rate and thickness of an oxidation film on the surface of a machining area. The graphitization of the metal-catalyzed diamond cutter can be inhibited, and the chemical wear of the metal-catalyzed diamond cutter is reduced.

Description

technical field [0001] The invention relates to the technical field of ultra-precision machining, in particular to a method and a device for inhibiting the chemical wear of a diamond tool by an oxidized metal surface. Background technique [0002] Compared with other cutting tools, diamond cutting tools have many unique physical and mechanical properties. However, its wider industrial applications are strongly limited due to its severe chemical wear in the direct cutting of many important metals and alloys, especially steel. Short tool life is thought to be primarily caused by metal-catalyzed diamond graphitization, which results from the intimate contact between carbon atoms on the diamond cutting edge and metal atoms on the freshly cut surface. To reduce chemical wear during diamond tool cutting, researchers have applied a variety of methods to reduce the rate of chemical reactions between carbon atoms and metal atoms, including cryogenic cooling, tool surface modificatio...
