Problems solved by technology

It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. Grinding wheels are the most widely used abrasive tools. They rotate at high speeds and can be used on metals or the outer circle, inner circle, plane and various profiles of non-metallic workpieces, etc., for rough grinding, semi-finishing and fine grinding, as well as slotting and cutting; the grinding wheel in the prior art can be used for long-term grinding. The waste is serious and the replacement frequency is high. In order to prolong the service time and service life of the grinding wheel, reduce the scrap rate and production cost, the invention proposes a high-strength bearing processing grinding wheel

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a high-strength bearing processing grinding wheel. Background technique [0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive that consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) with a certain strength. It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. Grinding wheels are the most widely used abrasive tools. They rotate at high speeds and can be used on metals or the outer circle, inner circle, plane and various profiles of non-metallic workpieces, etc., for rough grinding, semi-finishing and fine grinding, as well as slotting and cutting; the grinding wheel in the prior art can be used for long-term grinding. The waste is serious and the replacement frequency is high. In order to prolong the service time and se...
