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 superalloy...

specific Embodiment 1

[0082] Develop a brazed diamond grinding disc for grinding and polishing marine steel surface. Grinding disc size 125mm, inner hole 22.23mm

[0083]Due to the high strength and toughness of marine steel, diamond tools are prone to surface adhesion during processing. On the other hand, due to surface grinding and polishing, it is necessary to achieve a certain surface quality and not be too rough. Therefore, the design uses diamonds with a particle size of 45 mesh. HSD80 grade.

[0084] Due to the stable surface in the grinding and polishing process, a simple circular hole structure is used as the heat dissipation hole. The diameter of the circular hole is 3.5mm, and the abrasive grain width is 1.2mm.

[0085] The preparation steps are as follows:

[0086] (1) Use 0.2mm thick silica gel film and laser cut to prepare mesh partitions.

[0087] (2) Brush the adhesive on the area to be clothed on the surface of the grinding disc.

[0088] (3) Paste the mesh partition so that th...

specific Embodiment 2

[0094] A brazed diamond grinding disc for surface grinding of cast steel was developed. Disc size 180mm, inner hole 22.23mm

[0095] Due to the high hardness of cast steel, the amount of grinding and removal on the surface is relatively large, and the diamond tool requires low vibration and high efficiency during processing. On the other hand, there should be no obvious burn area on the surface after surface grinding and polishing, so the design uses diamond with a particle size of 35 mesh. Zhongnan ZND2290 grade.

[0096] Due to the complex grinding and polishing surface, a hexagonal structure is used as the heat dissipation hole. The length of the longest side of the hexagon is 3mm, and the abrasive grain width is 1.5mm.

[0097] The preparation steps are as follows:

[0098] (1) Use 0.2mm thick silica gel film and laser cut to prepare mesh partitions.

[0099] (2) Brush the adhesive on the area to be clothed on the surface of the grinding disc.

[0100] (3) Paste the me...

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...
