    Back in the old days Practical Machinist blah, blah, blah. I check in about once a week these days. This is what I see. The end is nigh.

    Huh? I thought you were Tapping...

    Either way. That's a big Tap. I wouldn't Tap that. I'd single point it on a Lathe or Threadmill it on a Milling Machine.

    When you go to a grocery store, and ask the produce person what herb to use in your marinara. And he says Oregano, but you were thinking Mint leaves. It doesn't make him a "Hater". We're adults here,...

    The disk is created by making good holes, in a timely fashion. IMO. I wouldn't want to disrupt that. If the disk is still there, why not send the exact same Drill through the hole after its done...

    Sooo add a toolchange and another operation? Why not just rotate it 180° and add a whole set-up? :dunce:

    OP, you can slow the Spindle Speed down at the very last second, for the break through.

    The idea of parting 5" Diameter anything is dumb. That's 2.5" stick out. Waaaay too much. Parting regular stuff off AND achieving a good finish is already a bitch. It's never going to be Parallel to...

    On the topic of work hardening---just because the bar you're Machining gets hot, doesn't mean it's getting hardened.

    Work hardening DOES NOT HAPPEN if the contact material is coming off....

    Nothing lasts forever. 2 ways to look at it. Treat the Machinery real nice for longevity. Or run the mother fucker into the ground, squeezing every cent worth of productivity out of it. Sometimes...
  12. If you're cutting it off, it won't work harden....

    If you're cutting it off, it won't work harden. That's the most basic logic. I'm not the best person to ask, because I push Turning centers to their limits. Max depth, max feeds, max spindle--for the...

    The center of the Drill has zero SFM. That's why it's hard to get good recommendations. I've had a lot of good things happen with that Drill. I'd take the speeds and feeds you used with 316 and...

    It's really a shitty pseudonym. It's not accurate, but it gets the point across.

    It's a Turning center, with an Axis that pivots along the Z Axis. Or an Axis that rotates through the Y Axis....

    I hate to admit it, but I like it. It's still a Haas. But it's sorta cool. It won't work very well, but it's a concept.

    B-Axis Lathes have a hard time with Rigidity, more than anything. That...

    Well now, that's helpful. Thanks for getting things pointed in the right direction. :dunce:

    I'm not seeing anything that justifies a B-Axis lathe. I think people just want to talk about them.

    CEO of Iscar/Berkshire is Warren Buffett. He's not a regular guy. He's a investments guy, a profiteer. I sort of doubt that anything other than double percent margins is interesting to him.

    Now just start saving for a second one. I had 2 face to face. One with a feeder, for first op's and one for second op's. They crank parts out. I don't understand the nay sayers, honestly this is the...

    So weird. This is the second post in a week about the same issue. I've never had a problem with it. I've never had to turn on an option for it. I've never had to change anything.

    I disagree. I've made more accounted moneys with Hardinge/Omni halfbreeds than any other single Turning center I can think of.
