NORZON is a composite abrasive in grinding wheels, often used in but not restricted to machining & foundry operations, hence the R.P.M. reference?

"When much of historic Gainsborough was ripped down in the 1960s, it was replaced by hideous buildings like this one, originally built in about 1965 for Abrafact Ltd., who made abrasive materials - grinding wheels and the like - and a lot of noise and dust for local residents. Abrafact changed ownership and name several times throughout the 1990s, and finally left the town (not sure if they went out of business or not) years ago." tatraškoda
