Abstract
Generally, end effectors for automatic robots can use ceramics such as alumina(Al2O3) and silicon carbide(SiC). In this study, black alumina was developed and used in the semiconductor field through powder molding press forming. The black alumina can be mass produced.Alumina and black alumina were ground using a plane grinder to apply to the end effector of an automatic robot. The optimal cutting conditionswere found by analyzing the surface roughness(Ra) of black alumina through grinding. The alumina surface roughness is the feed rate was about 0.72 mm/sec, and the number of revolutions was best at 0.4879 ㎛ at 1700 rpm. In addition, the black alumina surface roughness shows a precision of less than 0.2 ㎛ in most cutting conditions. The feed rate was about 0.72 mm/sec, and the number of revolutions was best at 0.1361 ㎛ at 1900 rpm. The surface roughness of black alumina was better than that of alumina by about 0.35 to 0.47 ㎛.
