In the process of superfinishing there is no significant thermal development. The edge zone is completely removed so that the undamaged, abrasion-proof base material becomes the load-bearing surface. As the base material is not thermally influenced, the risk of the formation of cracks or pitting due to changes in the microstructure is ...

Honing. Honing is a finishing process used to improve the geometry of a part, readjust the alignment of features such as holes or bores, and produce a finer surface finish. In the honing process, a small, bonded, abrasive stone or super-abrasive stick is rotated over the surface of a part over a controlled path.

Single stick tools. Single stick tools consist of a particularly rigid tool body which is able as far as possible to withstand bending forces. They are used where the straightness of the bore is a high priority such as with spools and valves. As opposed to the usual multi-stick honing tools, this tool is equipped with just one cutting stick.

Honing • It is a finishing process, in which a tool called hone carries out a combined rotary and reciprocating motion while the work piece does not perform any working motion. • The honing stones are held against the work piece with controlled light pressure. • It is desirable that 1. honing stones should not leave the work surface. 2.

the bearing ratio resulting in greatly improved wear resistance. Stock removal is typically in the order of a few microns. The achievable surface finish quality is comparable to levels reached only by honing or lapping. Superfinishing process is a very clean process, because coolant or grinding emulsion is used of honing oils like Stone grinding.

Usually, choose wide honing stick (stone) to hone soft materials, and choose narrow honing stick (stone) to hone hard materials. When honing the steel parts, the honing stick (stone) is narrower than that used for cast iron. The honing stick (stone) may be as wide as possible when honing small hole. The stone B≤25mm when honing big hole.

Through-feed superfinishing. In the through-feed finishing process two rotating drive rollers are used to both rotate and transport the rotationally symmetrical parts. This results in a (theoretically) infinite chain of workpieces, which are normally machined with finishing stones positioned above.
