Continued grinding produces even more heat, which produces more melting, which in turn causes the grinding operator to want to push down harder. Not only is this more labor-intensive, it results in more heat that causes loading. Longer aluminum chips coat the abrasive, which prevents the grain from doing its job.

Most grinding wheels are made of silicon carbide or aluminum oxide, both of which are artificial (manufactured) abrasives. Silicon carbide is extremely hard but brittle. Aluminum oxide is slightly softer but is tougher than silicon carbide. It dulls more quickly, but it does not fracture easily
