Maybe the resin bonded wheels just present new edges to the steel pretty easily. Diamond turning of steel is the holy grail of precision engineering. I don't think the speed has to be that high. We helped out a company that heats the steel with lasers, and it seems to work. Haven't seen what they have been up to lately.
