Abstract

The cylinder liners used in low speed engine are very important components. In general, the cylinder liners are machined by honing process. But, that process is not developed efficiently, so it is necessary to establish new machining process for cylinder liners of low speed engine.

In this paper, quantitative analytical accurate honing processing condition should be established and standardized about the currently adopted cylinders of low speed engine. Also it could be materialized by developing exclusive honing stone and automating oil groove processing machinery.

Furthermore, the information for machining process is acquired through analysis of component and observation of structure about liner's material. The way of GC honing stone machining process which have been used up to now is analyzed and then CBN honing stone machining process analyzed. Especially, CBN honing stone is tested in the middle of manufacturing for the first time.

Finally, the objective of this study is automation to innovate oil grooving processing by CNC equipment instead of the processing by hand. The performance test about invented CNC equipment for oil groove manufacturing is studied. Oil groove manufacturing has been done by hand so far. But people avoid the job due to lots of dust in the middle of processing. New concept of CNC manufacturing equipment is designed and made. The study proved the efficiency through the performance test.
