Smooth, accurate gears and optimum performance is the goal of any new design. Achieving those goals in the early design stage not only meets performance requirements but makes your design cost-efficient. A key component of this is being able to accurately predict dimensional changes due to any type of surface finishing. Other benefits include lower manufacturing costs and no time lost due to design error.

In a gear mechanism, the center distance between shafts and the tooth thickness of the gear define correct mesh and reliable performance of a gear train. To achieve an accurate gear mesh in a mechanism, it is necessary to account for any dimensional changes that may occur after surface finishing, case hardening or heat treatment.
