Abstract

The invention relates to a thermal-mechanical coupling edge grinding technology applicable to manufacturing diamond tools. The thermal-mechanical coupling edge grinding technology can solve the problem that the existing mechanical edge grinding technology of the diamond tools can not lead the sharpness of cutting edges of the diamond tools to be better than 10nm. The method comprises the followingsteps of: regulating an edge grinding machine tool of the diamond tools to be balanced; carrying out thermal treatment after carrying out fine-turning forming on a working surface of a steel grindingdisc, and carrying out fine polishing to achieve the mirror effect; carrying out fine dynamic balancing on a main shaft system of the grinding machine tool; clamping the diamond tool and regulating aclamp of a tool body to be horizontal; opening a gas source, turning on a power supply of the edge grinding machine tool of the diamond tools and regulating the revolution speed of a main shaft of the machine tool; adjusting the edge grinding direction of a front tool face to be easy to grind and regulating a front angle of the tool; and carrying out edge grinding on the tool under the conditionsthat the grinding speed is 33.96m / s, the grinding pressure is 5.95N and the grinding time is 5min. The technology is characterized by simple edge grinding technology, low cost and high efficiency andcan prepare the diamond tools with the sharpness of the cutting edges of being better than 10nm by edge grinding.

Description

technical field [0001] The invention relates to a sharpening process suitable for the manufacture of diamond tools, belonging to the technical field of ultra-precision cutting. Background technique [0002] Ultra-precision manufacturing technology is an important support and guarantee for the development of national high-tech industries and major scientific and technological projects. For example, in order to find inexhaustible clean new energy and alleviate the pressure of the energy crisis in the 21st century, western developed countries have put forward their own "advanced energy development plans". Confinerment Fusion, referred to as ICF) project". During the construction of the 192-beam laser light path of the ICF project, 7,518 high-quality laser-resistant optical components with a diameter of 410mm×410mm need to be processed efficiently and ultra-precision, and more than 200 million high-precision optical components with other diameters . Among the many optical com...
