Gear manufacturing

Gears can be manufactured by a variety of processes, including casting, forging, extrusion, powder metallurgy, and blanking.

As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.

Two machining operations, milling and broaching can be employed to form cut gear teeth.

The process is rapid and produces fine surface finish with high dimensional accuracy.

As produced by any of the process described, the surface finish and dimensional accuracy may not be accurate enough for certain applications.
