Superfinishing

May 11, 2009They probably can grind, hone and polish to an Ra of 4, but why? This requires they to do it tooth by tooth, gear by gear. To achieve this surface finish conventionally is both time consuming and expensive. superfinishing is a batch process where multiple gears can be processed simulataneously, thus lowering overall costs.

Superfinishing

Superfinishing is a process in which a rotating workpiece is finished by a relatively soft stone with fine abrasive oscillating parallel to the workpiece surface. The stone typically oscillates at an amplitude of 1–4 mm and a frequency of 10–50 Hz; and it contacts the workpiece at light pressure, typically 0.1–0.2 MPa.
