Drilling on 18-8 Staioless Steel : Concerning with the Surface Roughness and the Accuracy

Abstract

This paper describes the surface roughness and the accuracy of drilled hole on 18-8 stainless steel. I refered to my report "Adhesions between Various Tool Materials and 18-8 Stainless steel". The results are as follows : To prevent the adhesions between the stainless steel and the drill is most effective for good finish. For this purpose, Su1phurized Oil is effective as the cutting fluid. Concerning the drilling conditions, proper cutting edge angles, cutting speeds and feed speeds can be obtained. Low temperature drilling is effective, too, for slow feed.
