Three distinct grinding mechanisms have been found to occur when 304 L stainless steel is ground by alumina wheels. The first results in the grits becoming worn by attritious wear and occurs when temperatures in the grinding zone are relatively high, the second occurs at lower grinding temperatures and results in isolated, tiny areas of workpiece material adhering to grits while the third ...

Phenomenon of Wheel Loading Mechanisms in Grinding ...

Frequently, loading of the grinding wheel with chips occurs when ductile workpiece material is machined and leads to an early termination of tool life. Some recent investigations have shown that there are three principle mechanisms that cause the built-up of loading praticles with different shapes:
