What Is Superfinishing in Metalworking? | Blog Posts

Advantages of Superfinishing. There are several advantages of superfinishing, one of which is tighter tolerances. Most finishing processes involve the use of an abrasive to grind and remove material from a workpiece — and superfinishing is no exception. However, it uses abrasives with a finer grain than that of other finishing …

Gear Superfinishing: More Power, Less Friction

REM recently developed the Rapid ISF Process specifically for the automotive market in the effort to help improve efficiency and delivery time. Superfinishing a ring and pinion set, for example, removes the microscopic peaks created by the cutting and grinding associated with gear manufacturing, while the microscopic valleys remain untouched.

Superfinishing | SpringerLink

Definition. 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.

Supfina

Superfinishing is a chip removing machining process. But not one that is comparable to any other. In contrast to the classic lathe turning and grinding methods, there is full surface contact between the tool and the workpiece.This is precisely the feature that produces the unique characteristics of a perfectly machined surface.
