I'm interested in ExKenna's ripper mills. We like Iscar E90AL style insert mills and have several styles and sizes, I'm uncertain if I can improve my processes by making an investement in more tools. But if I think I can, I'll try.
Currently when roughing 6061-T6, we can get 7.5 cubic inches per minute of metal removal per spindle horsepower. With a 3" diameter cutter we can feed it at 100 IPM with .250 DOC with a full width cut. That calculates to 75 CI/Min. This is on a Cincinnati 10VC-1250 VMC rated at 10HP so that means 7.5 CI/Min/HP. A 2" cutter maxes at 150 IPM at .250 DOC full width, which calculates also to 7.5 CI/Min/HP. I haven't used our only Shear Hog lately, AB tools claims it will do 6 CI/Min/HP I remember it giving at least that much if not more.
What tools do you use, and what results do you get? Do solid carbide endmills produce more or less than this? Manufacturers all claim that their tools will improve productivity, I'd love to see some real world comparisons here.
