Abstract
It is necessary that the inner wall of the tiny nozzle used in a water jet cleaner is very smooth and also its nozzle edge is chamfered. Finishing of the inner wall of the tiny nozzle is very difficult by ordinary finishing methods. Gyration flow finishing method recently has been newly developed in which polishing is conducted using polishing fluid suspended peach seeds and grains into olive oil. Present study focuses on the effect of the polishing fluid supplied from the back side of workpiece. It is found that the suck out of polishing fluid from the back side of workpiece is very effective for chamfering of the nozzle edge. Experiments show that the size of the peach seed has an influence on chamfering quantity of the nozzle. It is shown that the jet force of the water jet cleaner of which nozzle is polished by the polishing method is made to increase by 30%.
