    Dad used to run a lot of 1215. Cut very well at 800 SFM and surface finish was acceptable. 4140 will always give a better part, but, depending on tooling, you may have to slow things down.

    Some Series 15 controls had color CRT's and FAPT programming, or the mill equivalent. It's kinda rare as 15s were very high level controls that didn't lend themselves to shop floor programming.

    Well, Okuma is the best IMO, but pricey and live tool Y axis versions are rare in the used market as they get snapped up VERY fast. The machine is just top drawer all the way.

    Doosan's SMX has a 12k milling spindle up top, 5k on the bottom. With that said, the normal turret arrangements all seem to be about 5k-6k for rotary tooling. With that said, spooling up lathe live...

    Position the tool -

    G0 X39. Z3.
    Then
    G32 Z-15. F1.5

    Then X42.

    The "F" is the lead of the knurl.
    Remember to ALWAYS have an X axis relief at the very next line.
