Abstract

The invention discloses a cutter cutting edge machining method, which comprises the following steps: a rough cleaning step: primarily cleaning a cutter to remove pollutants on the surface of the cutter; a wet-type sand blasting passivation step: wet-type sand blasting treatment is conducted on the surface of the cutter through a nozzle, and the machining condition of wet-type sand blasting is determined according to the type of the cutter and the material of the cutter; wherein the type of the cutter comprises a milling cutter and a fine trimming blade, and the cutter is made of high-speed steel and hard alloy; a fine cleaning step: after passivation, sequentially carrying out alkali liquor cleaning, acid liquor cleaning and pure water cleaning on the cutter, and finally cleaning by adopting an antirust agent solution; and a drying step: carrying out drying treatment after the cutter is finely cleaned. The cutting edge of the cutter manufactured through the method is smooth in surface,high in strength, even in stress in the cutting process and good in durability.

Description

technical field [0001] The invention relates to the technical field of industrial tool manufacturing, in particular to a tool edge processing method. Background technique [0002] In recent years, with the research and development of cutting technology, the requirements for tool durability and tool life are getting higher and higher. The cutting edge geometry has a crucial influence on the tool life and cutting performance. Tool edge preparation technology has been paid more and more attention. Tool edge preparation refers to the fine and ultra-fine deep processing of the micro-geometric shape of the formed cutting tool by the finishing method during the tool production process or before its use. By improving the microstructure morphology and stress state of the cutting edge and cutting area, the wear resistance and service life of the tool can be improved, and the stability of the cutting process and the quality of the processed workpiece can be improved. [0003] In the...
