Basically there are two types of grinding/polishing machine. The 'traditional' type which involves the mirror rotating at a relatively slow speed, a few rpm for a big mirror (16-20 inches) with the tool moving across the mirror, from side to side, at a higher rpm depending on the size of the mirror and/or tool.
You may notice that many commercial telescope advertisements proclaim they use "Hand Figured Optics" - in fact this is one of the best and least expensive ways to get an accurate surface on a mirror - most machines just can't hold the tolerances necessary, and any good telescope optic, including the mirror you could make in your kitchen, should be hand figured.
