Problems solved by technology

However, the heat-resistant stainless steel long rods purchased from steel mills have to be cut into short materials, and the shearing method will cause a lot of damage to the mold, and the sheared material has small cracks in the longitudinal direction. If it is cut with an ordinary grinding wheel, the wear of the grinding wheel is relatively large , and the knife edge consumes a large amount of stainless steel, which seriously affects product quality and labor production efficiency, and also causes great waste

Abstract

The invention discloses a stainless steel abrasive cutting wheel. The stainless steel abrasive cutting wheel is characterized in that abrasive cutting wheel raw materials comprise mixed abrasive particles, filler, a pore-forming material, resin and a reinforcing material; the mixed abrasive particles comprise black silicon carbide, monocrystalline fused alumina, brown fused alumina, brown fused alumina-cerium oxide core / shell composite abrasive particles and hercynite; the filler comprises zeolite and silicon carbide micro powder; the resin refers to phenolic resin modified by cardanol; and the reinforcing material refers to a glass fiber mesh containing graphite. The stainless steel abrasive cutting wheel has the advantages that first, the abrasive tool porosity is large and chips can be contained conveniently; second, the temperature of a grinding area is low and workpiece burning can be avoided; third, by the adoption of the chemico-mechanical polishing principle of cerium oxide, the microcosmic condition of a cut-processing surface is improved, and the roughness is lowered; fourth, due to the fact that different kinds of abrasive particles at different hardness are matched in the mixed abrasive particles, cutting efficiency is high; fifth, the cutting tool edge is narrow, the cutting surface is flat, and expensive cut materials are saved; sixth, by designing a grinding layer and a non-grinding layer, cost is reduced; and seventh, no fluoride is contained, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a stainless steel cutting grinding wheel and a preparation method thereof. Background technique [0002] Stainless steel has become a widely used engineering material due to its excellent corrosion resistance, good mechanical properties, processing properties and good welding performance. At the same time, through different polishing processing methods, the surface of various stainless steel plates, pipes, rods, and profiled materials can have different levels of surface finish, which greatly improves the appearance of stainless steel and makes it achieve aesthetic effects. Attractive, to people with the enjoyment of beauty. However, the heat-resistant stainless steel long rods purchased from steel mills have to be cut into short materials, and the shearing method will cause a lot of damage to the mold, and there are small longitudinal cracks in the material afte...
