Still fiquring out the new control, Seimens 840C. It's DOS based PC running DR DOS 6.0.
Question is what's the best set-up for drilling holes? I have 3 boring bar holders, 1.500" ID. Use a 3/4" straight shank arbor on on drill chuck and bush the 1.5" down to fit. Use a collet holder in there?
Un like my manual lathe I know you don't use the tailstock to drill holes, so what's the best way? it seems like you will use up a lot of Z space adding a collet holer or drill chuck to the front of the boring bar holder, is there another type of holder for this?
