Precision cutting method for diamond cutter

Abstract

The invention discloses a precision cutting method for a diamond cutter. The method comprises the following steps that S1, a workpiece is fixed and clamped on a precision digital controlled lathe; S2,the diamond cutter is arranged on a feeding box of the lathe; S3, a low-temperature carbon dioxide device is arranged, the positions of a first nozzle and second nozzle are adjusted, and a low-temperature carbon dioxide gas storage tank is opened; the first nozzle sprays low temperature carbon dioxide to the front cutter face of the diamond cutter, and the second nozzle sprays the low temperaturecarbon dioxide to the rear cutter face of the diamond cutter; S4, lathe equipment is started, the relative positions of the diamond cutter and workpiece are adjusted, and tool setting is completed; S5, diamond cutter turning technology parameters are set for turning; S6, after turning ends, the carbon dioxide gas storage tank is closed, a spindle, a power supply and a control software are turnedoff, and the diamond cutter and the workpiece are disassembled. The precision cutting method for the diamond cutter has the advantages that the service life of the cutter can be prolonged, the sharpness of a cutting edge is kept, and the machining quality and precision of the workpiece are ensured.

Description

technical field [0001] The invention relates to the technical field of precision cutting, in particular to a precision cutting method of a diamond tool. Background technique [0002] The bearing ring is one of the three major parts of the bearing, and it is mainly a thin-walled annular structure. Its processing quality has a direct impact on the precision, performance and service life of the finished bearing. Traditional bearing ring processing mostly adopts grinding-based processing technology. In recent years, with the development of new tool materials and coating technology, hard turning technology has been widely used in the processing of bearing rings. However, bearing steel is a typical difficult-to-machine and wear-resistant material, and its machinability is extremely poor. The hardened bearing ring combines the thin-walled difficult-to-machine structure and the characteristics of difficult-to-machine materials. How to ensure a reasonable tool life and the precisio...

Problems solved by technology

However, when the diamond tool cuts the iron-based material of the bearing ring, due to the high temperature generated by friction, the carbon atoms in the diamond react with the iron atoms on the surface of the workpiece or diffuse into the workpiece material, resulting in graphitization and oxidation of the diamond material, which is harmful to the tool. The life is greatly harmed, which affects the processing quality and precision
