Abstract

The invention discloses a ceramic grinding wheel for grinding a stainless steel nylon base body. The ceramic grinding wheel is formed by the following raw materials by weight part: 65-75 parts of abrasive, 25-30 parts of bonding agent and 3-5 parts of sodium silicate solution with volume concentration of 15 percent. The ceramic grinding wheel is firmly combined with the nylon base body in a bonding way, and the strength of the ceramic grinding wheel is greatly improved under the reinforcing action of the nylon base body, as a result, the special ceramic grinding wheel used when a stainless steel material is ground by an electric tool and a pneumatic tool is manufactured.

Description
