Surface finish study of Hard Milling 45 steel with PCBN tool

摘要

Experimental study on surface finish of high speed mill of hardened 45 steel was carried out with PCBN tool. Cutting parameters studied include different cutting depth, cutting speed and feeding speed. Surface finish after cutting were measured and compared with that of grinding. Experimental results showed that for high speed milling of hardened 45 steel, the surface finish can be very fine, different cutting parameters all have explicit effect on surface finish.
