Problems solved by technology

[0004] As the resin bond content increases, the hardness and compressive strength of the grinding wheel gradually increase; however, the surface of the grinding wheel with high resin bond content is more likely to be clogged

[0037] The resin grinding wheel to be prepared in this embodiment is a parallel grinding wheel, such as figure 1 shown.

[0038] First, raw materials with a certain weight ratio were weighed for batching. The types of raw materials and their parts by weight were 100 parts of brown corundum, 18 parts of phenolic resin, and 5 parts of cryolite. Wherein, a part of the phenolic resin is liquid and the rest is powder, and the weight ratio of the two is 1:2.

[0039] Then, put the brown corundum into the liquid phenolic resin to infiltrate, and stir well, so that the surface of the brown corundum particles is fully adhered to the liquid phenolic resin. After sufficient infiltration, mix the powdered phenolic resin and cryolite with the brown corundum, while continuing to stir until the three raw materials are fully mixed and even.

[0040] The mixed raw material granules are sieved, and the sieve openings of the sieve are 8-12 mesh, that is, the particle size of the available raw ...

[0044]The resin grinding wheel to be prepared in this embodiment is a cymbal type grinding wheel, such as figure 2 shown.

[0045] Similarly, batching is carried out first, and the types of raw materials and their parts by weight are respectively 105 parts of brown corundum, 10 parts of phenolic resin, 2 parts of cryolite, and 2 parts of carbon black. In the phenolic resin, the weight ratio of the liquid phenolic resin to the powdered phenolic resin is 1:4.

[0046] Then, put the brown corundum into the liquid phenolic resin to infiltrate and stir, and then mix the powdered phenolic resin, cryolite and carbon black with the brown corundum while continuing to stir until fully mixed.

[0047] Also use a sieve of 8 to 12 meshes to sieve the above-mentioned raw material particles to obtain a molding material.

[0048] The forming steps for cymbal wheels are slightly different from those for parallel wheels. Similarly, for example, to mold three grinding wheels at one time, fir...

Abstract

The invention provides a resin grinding wheel and a manufacturing method thereof, belonging to the field of grinding tools. The resin grinding wheel solves the problem that the traditional resin grinding wheel is easy to block. The resin grinding wheel comprises a grinding body and a reinforcing sheet which is arranged inside the grinding body to reinforce the rotation strength of the grinding body, wherein the grinding body comprises the following raw materials in parts by weight: 90-110 parts of brown corundum, 10-25 parts of phenolic resin and 1-10 parts of cryolite. The invention also provides a manufacturing method of the resin grinding wheel. The resin grinding wheel has the advantages of difficulty to block.

Description

technical field [0001] The invention belongs to the field of grinding tools, and relates to a resin grinding wheel and a preparation method thereof. Background technique [0002] Grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding agent. Among them, abrasive, bond and porosity are the three basic elements of grinding wheel. With the different abrasives, bonding agents and grinding wheel manufacturing processes, the characteristics of the grinding wheel may vary greatly, which has an important impact on the accuracy, roughness and production efficiency of the grinding process. Therefore, the appropriate grinding wheel must be selected according to the specific conditions. [0003] Resin grinding wheel is a grinding wheel whose binder is resin. It has the advantages of small grinding force, low grinding temperature, good self-sharpening, and high grinding efficiency. It is widely used in the grinding of hard and brittle mat...
