... cutting or turning operations can make use of ceramic-based tool inserts. Moreover, in high-speed bearings (so-called spindles), centrifugal forces vastly exceed the contact load, so hybrid ball bearings using silicon nitride balls with just 40% of the density of steel are now in standard use. The low...
