Abstract

The invention provides a resin grinding wheel and a manufacturing method thereof, which belong to the field of grinding tools and are used for solving the problem of the production of harmful sulfur dioxide by pyrite serving as a lubricating agent existing in the conventional resin grinding wheel. The resin grinding wheel comprises a grinding body and a reinforcing sheet which is arranged inside the grinding body for enhancing the revolving strength of the grinding body, wherein 90-105 parts by mass of corundum is taken as a grinding material the grinding body; 2-8 parts by mass of phenolic aldehyde resin liquid and 6-25 parts by mass of phenolic aldehyde resin powder are taken as bonding agents; and 1-10 parts by mass of cryolite and 1-5 parts by mass of polytetrafluoroethylene powder are taken as fillers. The invention further provides a manufacturing method of the resin grinding wheel. In the grinding wheel, the polytetrafluoroethylene powder instead of pyrite is taken as a lubricating agent, so that sulfur dioxide is not produced and other pollution is avoided in the using process.

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...
