Special abrasive particle landform for steel grinding abrasive disk and diamond abrasive disk and preparation method of special abrasive particle landform

Abstract

The invention discloses a special abrasive particle landform for a steel grinding abrasive disk and a diamond abrasive disk and a preparation method of the special abrasive particle landform. Abrasive particles are diamond abrasive particles, the diamond abrasive particles are arranged and distributed in a continuous linear or strip shape, and the adjacent linear or strip-shaped diamond abrasive particles form two or more closed heat dissipation areas in a surrounding manner. The shapes of the heat dissipation areas are axisymmetric. The heat dissipation areas are evenly distributed around the axis of the steel grinding abrasive disk. According to the special abrasive particle landform for the steel grinding abrasive disk, the arrangement of the diamond abrasive particles on the surface of the abrasive disk can be optimized, when steel is machined, the high heat dissipation effect is achieved, abrasive particle adhesion wear and the graphitization degree are reduced, the machining efficiency can be improved easily, and the diamond abrasive disk has higher economical efficiency and high economic value when applied to steel machining.

Description

technical field [0001] The invention belongs to the field of superhard abrasive tool preparation, and in particular relates to a surface topography scheme and a preparation method of a diamond grinding disc used for grinding steel materials. The prepared grinding disc can be applied to the grinding and polishing process of metals including cast iron, cast steel, general strength steel, alloy steel and other steel materials. Background technique [0002] The method of routine grinding and cleaning weld seam and welding scar at present is that the grinder carries out manual grinding with the manual grinder machine that resin emery wheel sheet has been installed. Resin grinding wheel is made of resin bond. Resin is used as bonding material, and metal powder, metal oxide, and ordinary abrasive are used as filler to form a bond. The abrasive and the binder are mixed according to the concentration requirements to make a molding material, which is molded and solidified by hot pres...

AI Technical Summary

Problems solved by technology

[0006] 3. During the grinding process, the sparks are large, the smell is large, and the dust is large, which is harmful to the environment.

[0007] 4. Low grinding efficiency

Compared with electroplating tools, it has 1. High exposure of abrasive grains

2. Large crumb space

[0019] Abrasive landform specially designed for iron and steel materials has not yet been described in detail in the literature. At present, diamond tools are mostly involved in stone processing, and the landform of the abrasive grain surface is also aimed at this field. It is related to nickel-based superalloys, titanium alloys, etc. Researched and analyzed the problem of abrasive grain topography optimization when the grinding wheel is grinding the outer circle. When the grinding wheel is used for steel grinding, the diamond surface topography is mostly designed as dots, clusters and other structures. The distribution of diamonds is discrete and non-continuous. The heat dissipation space is continuous and non-discrete. When actually processing steel with toughness and strength, problems such as cutting discrete force, grinding vibration, and point-like area adhesion are prone to occur.
