Application of sugar-based-polyol to working fluid in wire saw

Abstract

Hydrogenated starch hydrolysate is a sugar-based-polyol produced by hydrogenation of starch, which is widely used in the cosmetic and food industries. In this study, hydrogenated starch hydrolysate was used as the working fluid in a diamond wire saw. The processing performance varied depending on the usage conditions. With a concentration of 70% -54% , the satin finish on the surface of soda glass was reduced and excellent processing efficiency and chipping were achieved. When diluted with ion-exchanged water and used at a concentration of 5% - 3% , it showed equivalent or better machining performance compared to use of ion-exchanged water alone, and the wear of the machining tool was further reduced.
