Advancements

Manufacturers are continually pushing the envelope inregard to what can be accomplished with the single pass Honing Process. Improved tool, fixture and ma-chine designs have allowed for increased production rates as well as improved bore precision. The following are some of the latest advancements that have been made.

Long Length To Bore Ratio

One of the myths that has been associated with the single pass Process is that it is only well suited for finishing relatively short bores. As illustrated in some of the case histories in this paper, bores with length to diameter ratios of over 10 to 1 do not present a problem. With the proper tooling, fixture, and machine tool, the single pass Process is even capable of removing a camber or “banana” condition from the bore in many Applications.
