Cutter head passivating and grinding abrasive and preparation method thereof

Abstract

The invention discloses a cutter head passivating and grinding abrasive and a preparation method thereof. The cutter head passivating and grinding abrasive comprises 100-120 parts of walnut shell particles, 20-30 parts of black corundum, 3-6 parts of green silicon carbide, 3-6 parts of boron carbide, 5-10 parts of chrome corundum, 1-3 parts of diamond micro-powder and 2-3 parts of industrial gear oil. The preparation method is simple; the prepared abrasive has high hardness and mechanical strength; the cutter head passivating and grinding abrasive provided by the invention has effects of being able to polish or passivate a surface of a cutter, particularly increasing cutter polishing or passivating efficiency, also having relatively wide range of application, and being able to polish cutters or molds made of hard alloy, ceramic, metal and many other materials.

Description

technical field [0001] The invention relates to the technical field of grinding materials, in particular to a passivation grinding material for a cutter head. Background technique [0002] With the development of my country's industrial technology, especially the development of numerical control technology in recent years, the application of cemented carbide cutting tools in the fields of automobiles, molds, and aerospace has become more and more extensive. The cemented carbide tool has a sharp edge after it has just been ground, and direct use will greatly reduce the service life of the tool. In order to prolong the service life of the tool, it is often necessary to passivate or polish the sharp edge. Currently on the market Commonly used passivation abrasives are relatively simple. For example, in the patent application number 201510827632.X, the name is "a kind of abrasive for tool polishing or passivation", which discloses a formula abrasive mixed with broken walnut peel...

Problems solved by technology

The cemented carbide tool has a sharp edge after it has just been ground, and direct use will greatly reduce the service life of the tool. In order to prolong the service life of the tool, it is often necessary to passivate or polish the sharp edge. Currently on the market Commonly used passivation abrasives are relatively simple. For example, in the patent application number 201510827632.X, the name is "a kind of abrasive for tool polishing or passivation", which discloses a formula abrasive mixed with broken walnut peel particles and diamond powder; In the patent No. 201610882805.2, titled "A Process for Passivating Industrial Tools", diamond powder is used as the abrasive for passivation. It can be seen from the above that the current passivation grinding has a single abrasive composition and low passivation polishing efficiency.
