Problems solved by technology

As we all know, in order to make the steel ball grinding wheel have higher durability, the hardness of the grinding wheel is higher, and the grinding efficiency will decrease at this time; on the contrary, if the grinding efficiency is to be improved, the hardness of the grinding wheel must be reduced, and the durability will decrease

Abstract

The invention relates to the technical field of grinding wheels and particularly discloses a steel ball grinding wheel formula. The steel ball grinding wheel formula comprises, by weight part, 18-24 parts of a brown fused alumina grinding material, 6-12 parts of a white corundum grinding material, 10-20 parts of a silicon carbide grinding material, 20-30 parts of feldspar, 15-20 parts of clay, 2-5parts of borax glass and 25-40 parts of a binding agent. By means of the steel ball grinding wheel formula, defects of the prior art are overcome; steel ball grinding wheels are made of the brown fused alumina grinding material, the white corundum grinding material, the silicon carbide grinding material, the feldspar, the clay, the borax glass and the binding agent; high durability is achieved, and high grinding efficiency is achieved; and meanwhile, heat resistance is good, and the roasting yield is high.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a formula for grinding steel balls and grinding wheels. Background technique [0002] Steel ball grinding wheel is a special grinding wheel for grinding spherical steel balls with a diameter below 76.20mm. It has the characteristics of large size, fine particle size, high hardness, and high density. It is widely used in machinery and bearing industries. At present, all steel ball grinding wheel manufacturers use brown corundum and silicon carbide mixed abrasives to manufacture steel ball grinding wheels in formula design. There is a certain limit, so the grinding wheel is required to have a large shrinkage after burning to increase the density of the grinding wheel. The refractoriness of the binder should not be too high. Therefore, if the fine-grained abrasive of a single brown corundum is used, because of the high impurity content in it, the grinding wheel is easily fo...
