Problems solved by technology

Resin grinding wheels have the characteristics of high strength, high elasticity, impact resistance, and firmness. However, many problems often occur in the manufacture of resin bonded grinding wheels in the prior art. Open to form agglomerates, dry inside and wet outside, which not only changes the ratio of the process, affects the development of organic abrasive manufacturing technology and the improvement of product quality, but also causes a lot of waste of raw materials, followed by resin grinding wheels after manufacturing and forming

Example Embodiment

[0022] A method for preparing a resin grinding wheel. The material mixing process is carried out in a fully enclosed environment, which includes the following steps:

[0023] The first step: Take 30~34 parts by weight of white corundum and 24~28 parts by weight of single crystal corundum into a mixer and mix to form a mixed abrasive, then add 2~3 parts by weight of anthracene oil and 5~8 parts by weight of phenolic resin liquid and mix well After the mixed abrasive is completely wetted, 4-9 parts by weight of furfural, 1-2 parts by weight of creosote oil, phenol or methoxy cresol are added in sequence, and then 3-6 parts by weight of cryolite, 2~ 5 parts by weight of naphthalene granules, plastic particles, and hollow alumina are mixed uniformly, and finally 5-10 parts by weight of phenolic resin powder are added and mixed uniformly, passed through a 250-mesh standard sieve, and screened twice. The particles that pass the standard sieve are used as molding materials for grinding ...

[0031]

[0032] The preparation process is as follows:

[0033] Put the white corundum F12 and single crystal corundum F24 into the mixer according to the proportion weight and mix to form a mixed abrasive. Then add 3 parts by weight of anthracene oil and 8 parts by weight of phenolic resin liquid and mix evenly. After the mixed abrasive is completely wetted, add 9 Parts by weight of furfural, 2 parts by weight of creosote oil, phenol or methoxy cresol are mixed uniformly, then 6 parts by weight of cryolite, 5 parts by weight of naphthalene particles, plastic particles, and hollow alumina are added and mixed evenly, and finally 10 parts by weight of phenolic resin are added The powder is evenly mixed, passes through a 250-mesh standard sieve and sieved twice. The particles that pass the standard sieve are used as the molding material for grinding wheel molding;

Abstract

The invention provides a resin grinding wheel preparation method. A resin grinding wheel is prepared by combining multi-granularity white corundum, monocrystalline fused alumina, anthracene oil and phenolic resin liquid with furfural, kreosote, phenol or kreosol and cryolite, naphthalene grains, plastic particles and hollow alumina filling according to a certain weight ratio. By implementing the method, powder cannot be wrapped by wet materials in the process of mixing of materials, and influence on quality of a resin grinding wheel product due to the fact that the materials are not dispersed and cake is avoided. In addition, a certain weight part of silicon carbide is added in raw materials of mixed grinding materials, and grinding wheel cutting pieces different in performance can be acquired by controlling proportioning content of a silicon carbide grinding material, mixed white corundum and monocrystalline fused alumina and adjusting content of a wetting agent and phenolic resin powder within a certain range.

Description

technical field [0001] The invention relates to a preparation method of a resin grinding wheel, which belongs to the technical field of "B24D tools for grinding, polishing or sharpening" in the international patent classification table. Background technique [0002] The grinding wheel is a circular consolidated abrasive tool with a through hole in the center, which is made by mixing abrasives and binders, compacting, drying, and firing. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed during use. It can be used for rough grinding, semi-finishing, fine grinding and opening of the outer circle, inner circle, plane and various profiles of the workpiece. Tools for machining such as grooving and cutting. Grinding wheels can be divided into resin grinding wheels, rubber grinding wheels, metal grinding wheels, and ceramic grinding wheels according to different types of binders. Among them, the resin grinding wheel is a grinding wheel made of ...
