High speed slurry flow finishing of inner wall of stainless steel capillary -effects of slurry injection pressure on polishing performance

摘要

In the field of precision machinery, stainless steel capillaries with fine hole and long size has been needed for the flow line of pure gas and liquid. Inner wall of such a capillary should be finished with high precision for favourable flowing characteristics of fluid through the capirally. In our previous work, new polishing method, in which polishing is performed by flowing slurry through the capillary at high velocity, has been developed, and it has proved to exibit excellent polishing performance. In the present report, effects of slurry injection pressure on the polishing performance have been studied.
