Friedrich Fischer builds the first ball grinding machine, used to grind hardened steel balls in large batches with absolute spherical precision. Thanks to this innovation, the ball bearing's success spreads around the world. 1905 The trademark "FAG", Fischer Aktien-Gesell-schaft, is registered, and the "FAG" brand is born. 1990

This hardens the balls, but it also changes their size. The size of bearing balls has to be perfect, sometimes within millionths of an inch, so a few more operations are needed after heat-treating. The balls next go through a grinding operation. The same kind of machine is used, but this time the coolant contains an abrasive.
