ATLANTIC :: Grinding processes
Grinding processes. Grinding is a process with numerous geometrically undefined cutting edges/abrasives, which are integrated in the grinding wheel. Grinding is a manufacturing technique for machining surfaces with abrasives. The rotating grinding wheel performs the cutting motion, while the feed motions are conducted by the grinding wheel or ...
A Comparison of Honing and Lapping - Metal Cutting Corporation
The lapping process is more gentle than honing and removes much less surface material. Therefore, the workpiece should be as close as possible to final size — achieved, for example, through double-disk grinding — because lapping typically removes only 0.0005" to 0.005" (0.0127 mm to 0.127 mm) of material.
For Superfinishing Excellence, Start With The Right Finish ...
Ideally, grinding and superfinishing operations should be synchronized to achieve the common goal of producing consistently good parts at the end of their interrelated processes. The grinder needs to take the workpiece to size within a prescribed semi-rough finish range and then leave it alone.

An Introduction to Superfinishing | Modern Machine Shop
"When you turn or grind a part, the depths of cut could range from 50-100 microns or higher," Keshavan says. "Removing that amount of material in a short amount of time requires lot of energy, and the part heats up. Superfinishing removes 1-2 microns of stock on radius and requires less energy."

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.

Superfinishing Gears--The State of the Art
Superfinishing hardened gear surfaces using conventional techniques, such as grinding and/or honing, however, has sev-eral serious drawbacks. Not only are such processes costly and time consuming, but there is always the risk of permanently damaging the gear by either destroying the tooth profile or introducing grind burn.

Supfina - Superfinishing
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.

Machining vibrations caused by the eccentricity of the mass of the pins in relation to the journals increase the difficulty of achieving a stable and capable process.
Grinding and finishing processes - ScienceDirect
Superfinishing processes. Honing is widely used in conventional superfinishing practice, but honing stones become glazed and lack consistency and the ability to be controlled from a process viewpoint. The skill is operator-dependent and is usually a process that is used for correcting the profile of diamond tools used in the grinding process.
What Is Superfinishing in Metalworking? - Monroe ...
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 processes.
