Problems solved by technology

However, the stainless steel material is relatively special, containing a relatively high content of nickel, chromium and other viscous metal components, the material has good toughness and is not easy to process
At present, the grinding efficiency of ordinary resin or ceramic grinding wheels is low, and the grinding debris is easy to adhere to the surface of the grinding wheel and cause burns. At the same time, the abrasion is high and time-consuming. The grinding of stainless steel has always been a technical problem.

Abstract

The invention discloses a ceramic superhard grinding wheel for grinding double-end surfaces of stainless steel products and a preparation method thereof. Non-equal-area cBN mixture, diamond abrasive accounts for 50-90% of the total weight of the main abrasive. Adopting the scheme of the present invention greatly reduces the occurrence of sticking chips and workpiece burns in the process of grinding and processing stainless steel workpieces, and at the same time improves the processing efficiency; the present invention also discloses the preparation of the above-mentioned special ceramic superhard grinding wheel for grinding the double-end surfaces of stainless steel products method.

Description

technical field [0001] The invention relates to a ceramic superhard grinding wheel for grinding double-end surfaces of stainless steel products and a preparation method thereof. Background technique [0002] Due to its high hardness and strength after nitriding, stainless steel is more and more widely used in the manufacturing industry. However, the stainless steel material is relatively special, containing a relatively high content of nickel, chromium and other viscous metal components, the material has good toughness and is not easy to process. At present, the grinding efficiency of ordinary resin or ceramic grinding wheels is low, and the grinding debris is easy to adhere to the surface of the grinding wheel and cause burns. At the same time, the abrasion is high and time-consuming. Grinding stainless steel has always been a technical problem. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to pr...
