Grinding Aluminum

Aluminum melts easily, and if you were to try to grind down aluminum, it would start to melt and the aluminum would coat the wheel. The stone would grind the aluminum for a while, but particles would start getting embedded in the pores of the stone. And the next time the stone comes around, there's no grit exposed, only little bits of aluminum.
