Material Removal Rate
A simple explanation for this type of behavior is that a decrease in removal rate results in a smaller undeformed (uncut) chip size, causing more flow and less brittle fracture. Results for specific grinding energy versus average uncut chip cross-sectional area in Figure 3.19 for aluminum oxide and silicon nitride show two distinct regimes [26].

Grinding Aluminum
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. So the aluminum on the piece rubs against the aluminum on the wheel, producing more heat, which produces more melting, and so on.
