A grinding wheel is one of the tools used in machining, but what exactly is a grinding wheel? Let’s take a particular grinding wheel as an example, and have a closer look at the structure using a microscope. Grinding wheels are generally composed of the 3 elements “abrasive grains (grains)”, “bond” and

Throughout the grinding wheel's history, the bond that holds the abrasive grains together has proven as important as the grains themselves. The success of grinding wheels began in the early 1840s, when bonds containing rubber or clay were introduced, and by the 1870s a bond with a vitrified or glass-like structure was patented

Dec 07, 2018 Resin bond grinding wheels are used for stainless steel cutting, grooving, and centerless grinding. It has high strength, good elasticity, shock-free and many porous and can be used for high peripheral speed (35-75m/s). But resin bond grinding wheels have low hardness. If put the resin grinding wheel into the paraffin wax, it can prevent the
