Problems solved by technology

It has been widely used in the grinding industry, but after long-term application and research, it is found that resin grinding wheels have major defects in the use process: 1. Resin grinding wheels have poor water resistance, poor alkali resistance, and short shelf life
3. During the grinding process, the sparks are large, the smell is large, and the dust is large, which is harmful to the environment.
4. The grinding efficiency gradually decreases
Compared with electroplating tools, it has 1. High exposure of abrasive grains
2. Large crumb space
[0015] At present, grinding wheel dressing measures are often used to control the contour of abrasive grains, so that the edges of abrasive grains are even. During the grinding process, there is a phenomenon of local fragmentation of abrasive grains in the repaired high abrasive grains, forming new micro-edges, which is conducive to grinding. cutting, but there is a possibility of reducing the grinding life
Moreover, the grinding of single-layer brazed diamond tools has high requirements for grinding tools, high cost and complicated process, which is not conducive to batch preparation of diamond grinding discs for grinding steel

specific Embodiment 1

[0058] Preparation of a brazed diamond grinding disc for grinding carbon steel surface rust and surface.

[0059] The scheme design and steps are as follows:

[0060] (1) Since the surface of carbon steel is required to be polished, the removal amount is small, and it is hoped that there will be no obvious scratches on the surface after grinding, so the diamond particle size should not be too large, and the particle size range should be within 20%. Therefore, we choose to use Huanghe Cyclone HSD80 grade 50 / 60 mesh artificial diamond. The diamond particle size in this range is 0.25mm ~ 0.30mm, which meets the particle size requirements.

[0061] (2) The diamonds are arranged in a dotted array on the surface of the grinding disc, and a 0.2mm thick spacer plate is used as a spacer, and small holes are drilled in the part where the diamonds are arranged by laser drilling.

[0062] (3) The substrate is machined with 45 steel to prepare the disk body, and the diamond part is arrang...

specific Embodiment 2

[0070] Preparation of a brazed diamond flat grinding disc for grinding casting surface burrs and risers.

[0071] The scheme design and steps are as follows:

[0072] (1) Since it is required to grind the surface of cast steel, it is not only necessary to grind the burr, but also to cut and grind the riser, so it is most suitable to use a flat grinding disc. Due to the large processing allowance, it is hoped that the processing efficiency will be high, and there will be no obvious scratches on the surface after grinding, so the diamond particle size should not be too small, and the particle size range should be within 15% of the fluctuation as much as possible. Therefore, the Yellow River Cyclone HSD80 grade 35 / 40 mesh artificial diamond is selected. The diamond particle size in this interval is 0.425mm to 0.500mm, and the range is greater than 15% and less than 20%. In order to further control the accuracy, the particle size is screened twice to control The particle size ran...

Abstract

The invention discloses a brazed diamond grinding disc for steel grinding. The particle size interval of diamond particles of the brazed diamond grinding disc is 20 meshes to 120 meshes, and the particle size floating range of the diamond particles of the single diamond grinding disc does not exceed 20%. Diamond cutting edges are flush, and the top ends of diamond abrasive particles are kept to be a molded surface and perpendicular to the normal direction of a base body. The diamond grinding disc for steel grinding can conduct high-quality and high-efficiency machining on the surface of a steel material. By controlling the particle size interval of diamonds on the surface of the grinding disc and the positions of the surface cutting edges, the surface of the steel material is ground and cleaned on the premise that the particle size grade of the diamonds is not reduced, and the aims that the surface roughness meets the requirement and the machining efficiency is high are achieved. The grinding disc not only can be applied to grinding the surface of the steel material, but also can be prepared into other shapes so as to carry out plane grinding, end face grinding and the like on the material, and is an innovative process with wide adaptability.

Description

technical field [0001] The invention belongs to the field of superhard abrasive tool preparation, and in particular relates to a brazed diamond grinding disc for steel grinding and a preparation method thereof. Background technique [0002] The conventional method of polishing the surface of steel materials is to manually polish with a manual grinder equipped with a resin emery wheel sheet. The resin grinding wheel uses resin as the bonding material, and metal powder, metal oxide, and ordinary abrasives as fillers to form a bonding agent. The abrasive and bonding agent are mixed according to the concentration requirements to form a molding material. After hot pressing, molding, After solidification, the green body of the product is made, and the finished product is processed after subsequent processing. [0003] The resin grinding wheel used for grinding steel materials is made by using the principle of resin curing to consolidate superabrasives such as silicon carbide into...
