    How close do you rapid?

    I like to see .1 on all my feed/return planes. It's a good round number. I can see it matches my position with a glance. I don't need to get my calculator out to see if distance to go is a crash. .15 with a feed plane of .1, is pretty easy to understand. .125 with a feed plane of .05, takes a...

    Hyundai sub spindle alignment.

    Thank you. Not quite as helpful as that 2nd post :rolleyes5:. When you say "trucks" what are you referring to? I believe that's what needs to happen

    Hyundai sub spindle alignment.

    I'm working in a Hyundai-Kia skt 21 lms (no Y axis). The sub is not in line with the main. I've been fucking around with it all day. It appears (note that I could be and regularly am wrong) but it appears as though the sub is on a pivot pin. So I can fix taper with push/pull screws and bolts...

    Counterboring in aluminum on lathe with live tooling

    I know this seems like a very non-conventional way to do it, since you have Live Tools. Have you considered using a Boring Bar? R

    Small Diameter Deep Hole Drilling

    I think I get it. His boss is an old time Tool maker. So when it's short quantity, his mentality is to build the Tools you need. Including hole making. If Monochrist or Termite were here he'd be talking about D-bits. So maybe the OP needs to learn that skill.

    Bar runout

    I gave you solutions that require very little time, just a change in operations. Cold roll isn't round, it isn't straight. Also you don't know the vendor, if it's customer supplied. Could be Chicom shit. 12,000 pieces isn't that much, your guys will get very fast at using a deadblow. R

    Turning 18" D2 Steel plz help speed/feed/doc

    I'd go go go until the motor can't push anymore. Then back it off a cunt hair. If you blow the machine up, use it as logic to get an Okuma. By the sounds of your set up, Haas is probably not the right equipment. OTOH, you might be more successful doing some major removal by Roughing on a 3A...

    1 1/4 - 11 1/2 internal thread

    Notice, your starting position is greater than your finished Major Diameter. That's why your R value isn't acting accordingly. Use 1.4 as a start position, then it's smalker than you finished Major Diameter., and your Minor Diameter. I understand your logic, but the controls function needs to...

    Finish issues with tiny boring bar in 4140HT

    Were it me, I'd buy the best, slickest, wazzoo Drill ever. I have maintained tolerances like that woth an MA Ford Twister drill. Everyone makes it, 3 flute, high helix carbide Drill. I'm not implying this is THE solution, but I'd try it. Aligning tiny bars can be a bitch. I usually align it in...
