The invention discloses a
grinding wheel manufacturing method which comprises the following steps of material mixing, wherein quantified
grinding materials and binding agents are mixed and prepared according to a technical formula;
extrusion forming, wherein the prepared
mixed materials are added in a die cavity to be extruded and formed; curing and
sintering, wherein a formed
grinding wheel is placed in a curing oven or a curing
kiln for curing. In the material mixing process, a certain ratio of functional filling with is further added to be mixed with the grinding materials and the binding agents. After the
mixed materials are extruded and formed at normal temperature, the
mixed materials are subjected to at least one more
extrusion after being softened at
intermediate temperature. Compared with the prior art, the
utilization rate of the
grinding wheel grinding materials is improved in the way that the new functional filling is added in the material mixing process on the basis of the existing production technology, the intermediate-temperature
softening process and the high-temperature and high-pressure forming process are added based on the primary cold press forming, an assembling line production mode is adopted, production efficiency is improved, and produced grinding wheels have the advantages of being good in binding power, high in grinding efficiency and abrasion resistance, little in dust, and the like.
