According to Steve Fussell, manufacturing manager, the primary benefit of grinding for gear production has historically been the improved gear quality after heat treating to produce near-perfect symmetry and micro-finish, which results in very quiet gears. It is also necessary as a finishing process after many roughing operations.

Boring is a cutting process that involves the use of a single-point cutting tool or boring head to enlarge an existing hole in a workpiece. This is in stark contrast to drilling, which is performed to create an initial hole in a workpiece. Boring processes are typically performed using a lathe, milling machine or a horizontal boring mill.
