Another Look at Grinding vs. Hard Turning: .

    Although grinding is known to produce good surface finishes at relatively high feed rates, hard turning can produce as good or better finishes at significantly higher material removal rates. The turning process consists of small depths of cut, yet estimates of reduced machining time are as high as 60 percent for conventional hard turning and 90 percent for the latest plunge turning techniques.

    Hard turning is typically defined as the turning of a part or barstock of harder than 45HRC on a lathe or turning center. Since surface roughness of Rmax/Rz=1.6s can be achieved, hard turning is often considered a replacement for grinding operations or as a pre-grinding process. Hard turning is most often performed on post-heat treated parts with surface hardness ranging from 45HRC to 68HRC or ...
