Problems solved by technology

However, due to the influence of factors such as the viscosity of the resin bond and the mixing and stirring equipment, the filler and the abrasive are mixed unevenly, and it is more difficult to mix the filler with the stabilizer evenly. The composition of the resin grinding wheel after entering the press molding process is distributed uneven

Embodiment 1

[0019] To make resin wheel cutting discs:

[0020] Select the bonding mixed abrasive with the following ratio, and the ratio is as follows by weight percentage:

[0021]

[0022] Its preparation process is as follows:

[0023] Put 24# brown corundum into the mixing pot according to the proportion and weight to mix evenly, then add the mixed solution of resin solution, diluent and epoxy resin solution, after the brown corundum abrasive is completely wetted, add cryolite and polytetrafluoroethylene powder in turn , glass fiber and gypsum powder, after mixing evenly, add resin powder and continue mixing until the powder is evenly attached to each abrasive. Then weigh according to the single weight of the cutting piece and then feed the material. Before feeding, put the grinding wheel mesh, spread the material with a scraper, put a grinding wheel mesh after it is flattened, press the pressure plate to form, and then harden.

Embodiment 2

[0025] To make a resin grinding wheel:

[0026] Resin grinding wheel bonded mixed abrasive formula, the ratio by weight percentage is:

[0027]

[0028] Its preparation process is as follows:

[0029] Put 30# brown corundum into the mixing pot according to the proportion and mix evenly, then add the mixed solution of resin solution, diluent and epoxy resin solution, after the brown corundum abrasive is completely wetted, add cryolite and polytetrafluoroethylene powder in turn , glass fiber and gypsum powder, after mixing evenly, add resin powder and continue mixing until the powder is evenly attached to each abrasive, and place nuts or skeletons on the operating table. Different grinding wheels have different accessories, according to the single weight specification of the grinding wheel , drop into cohesive mixed abrasive, spread the material, scrape, and harden after pressing and forming with a pressing plate, and become the resin grinding wheel of the present invention....

Abstract

The invention discloses a method for preparing a resin grinding wheel containing epoxy resin. The resin grinding wheel containing the epoxy resin comprises 0%-80% of 14#-80# brown aluminum oxide, 0.5%-10% of resin liquid, 0.2%-10% of epoxy resin liquid, 0%-5% of a thinning agent, 5%-20% of resin powder, 0%-5% of glass fibers, 1%-15% of gypsum powder, 0.5%-15% of polytetrafluoroethylene and 1%-20% of cryolite. The resin grinding wheel containing the epoxy resin has the advantages that due to the group resistance of the epoxy resin, the degree of deformation of the grinding wheel can be lowered, the service life of the grinding wheel is prolonged, the repair and maintenance frequency of the grinding wheel can be reduced for a worker when the wheel is used, the production efficiency is improved, the fatigue strength during work is reduced, the grinding wheel contains no resin group or abrasive material group point after being hardened, and the degree of finish of a ground workpiece can be effectively improved.

Description

technical field [0001] The invention relates to a method for manufacturing a resin grinding wheel containing epoxy resin, which belongs to the field of cutting instruments. Background technique [0002] At present, when using resin grinding wheels, products with low resin content have a large cutting or grinding loss, and products with high resin content are prone to burning and bursting during cutting, and it is easy to cause the workpiece to turn blue during grinding, making it impossible to perform grinding work. In addition, because both the binder and the filler are powdery, dust is easily generated during the production process, which seriously pollutes the environment. At the same time, during the operation of the grinding wheel, the abrasive grains will gradually break and fall off due to continuous friction with the processed material, increasing the The instability of product surface quality and processing accuracy increases the fatigue intensity of employees and m...
