摘要
There are growing industrial needs of micro-drilling of engineering ceramics. Among the ceramics, little study was conducted on micro-drilling on silicon nitride. In the present study, micro drilling on two kinds of silicon nitride with different kinds of additives (Si3N4+ Y2O3 and Si3N4+ Al2O3) were, made in ethanol as the cutting fluid. The condition of the spindle rotational speed and the feed rate was clarified for safely drilling. The life of the diamond-coated drill is longer for Si3N4+ Y2O3 than for Si3N4+ Al2O3; referred to SiN-W, and SiN-B respectively. It is suggested that tribo-chemical reaction product; silicon alcoxide may effectively protect the damage of the drill point for SiN-W.
