Advancements
Manufacturers are continually pushing the envelope in regard 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.
Higher Bore Precision
Since all the diamond tools are set to specific sizes and do not require expansion during each cycle, the single pass Process is able to achieve unsurpassed size control in production (1μm with near perfect repeatability). These results are very predictable and repeatable, thus lend perfectly to Statistical Process Control.
