2021-11-18 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.

2015-1-1 5.1. Typology of the honing process. Honing is a technology for mechanical finish-machining of metallic parts and brittle-hard ceramic. According to DIN 8589 T14 , honing is defined as cutting with geometrically undefined cutting edges, during which multiedge tools conduct a cutting motion consisting of two components.At least one component of the cutting motion is a stroke motion, so that the ...

2014-7-17 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.

Belt grinding and polishing are very flexible machining processes with undefined cutting edges that use a large number of cutting particles. Depending on the abrasive belt selected, extreme high stock removal rates (1 mm and more per pass ) or super fine finishes can be achieved (Ra 0,1 µm and better).

2018-1-19 centerless grinding consists of two wheels; the grinding wheel and a regulating wheel. The workparts, which may be many individual short pieces or long rods (e.g.,3-4m long), are supported by a rest blade and fed through between the two wheels. The grinding wheel does the cutting, rotating at surface speeds of 1200-1800 m/min (4000-6000 ft/min).
