This is more a subject for the trades area. But here goes. You are actually most likely using too fast of a machine. There are few machines out there which have the power required at the low rpms and will not burn up doing it. Top polishing granite is almost an art. No one process works for all granites and no one process works for everybody. It is about reading the stone as you go but not over doing each grit so you leave the stone flat. It takes a lot of practice and some hands on coaching helps.
