    I would suggest you make a "gage" out of a solid piece of material and ream some holes in it where the holes should be. Drop your finished part on it and see if the holes line up with gage pins. This...

    I was wondering what the material is and how big. Is it like in that screenshot you posted, made out of a solid bar? Is the material cold rolled?

    I didn't calculate radii or pay enough attention...

    While you could do something macro-wise and have it do one or the other M-code...


    Can you make a new M-code on the machine where M428 hangs?

    Just mill the ends of the jaws (straight line in Y)

    Then you can just indicate the ends of the jaws up.

    Or, what I usually do is just put the jaws in with the screws barely snug, then clamp on...

    Nooooo, I'm emotionally invested in figuring it out!

    Do you think they just googled "Sandvik drill forum" and clicked the first result to get here?

    Edit: Just checked, 2nd result.

    I think we can work through this, although this isn't the normal kind of drilling most of us do.

    Without knowing ANYTHING about what you're working with:

    Does it have a cooler/radiator? Is it...

    Rarely run any brass or leaded steels. Occasional 12L but mostly we run various steels like 10xx/41xx/4340/8620, 303/304/316/410/17-4 SS, and 5083/6061/7075 aluminums, with the occasional cp2...

    Are you suggesting that fresh scent I get from mixing bleach and ammonia* might not be very good for my health???

    Not great. Back then, we had switched from Trim Sol (which was a tad expensive, and the work was slow, so my work was trying to save a bit of money) to some "no-name" coolant (I am sure it had a...

    We are running 795-H, and have noticed similar issues within the last couple years.

    A couple machines have had the coolant separate after 6-12 months, and the largest machine in the shop (with...
  14. My question is, what kind of vises are you using?...

    My question is, what kind of vises are you using? 6 inch kurt or similar? How far apart are they spaced. What are you doing with the part?

    For less clamping time and depending on what you are...

    After looking up the spec on which port you are doing, I would say that you'll be fine.

    We do those same ports (although usually in steel, not extra long, and never bigger than 1/2 tubing which is...

    Well, I do still have the long hair to do it. But I haven't been to a metal concert in the last few years. Last show was, uh, Exodus maybe? In 2015.

    Do you have any constructive information to copy paste, or are you still going on about 10000 tools and their runout values?

    I agree with that. However, I wonder if this job is military work and the material needs to be DFAR compliant. I know I have had to make plate stock round in the past. I have no idea if the mcmaster...

    Cut round blanks out of plate (laser, water jet, or simply mill them. Hougen drill even?) and send them over to the lathe.

    Let me ask you: do you even have the means to measure surface finish?

    I do. If it was aluminum.

    It would not be a problem if you could bolt it down to the table with cap screws in the center.

    But you would probably want to space the center rows further apart if...

    I'm also in the vise camp with this one. Besides, if you mill sets of round jaws, you can technically use them on another job if you get another that requires that size diameter stock. We've got a...

    He's drilled over 100000 3/8 holes.

    He didn't mention speeds and feeds, but lets say he's using a 10" long drill at 5 inches a minute. For simplicity, we are negating any time lost during pecks...

    If you only have a couple hole size ranges (say around .75 and around 1.25), I'd get individual boring heads from a good company. We tend to have mostly Parlec heads. .0001 adjustment, short tool...
