How do they get the balls in ball bearings so perfectly …
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.
