    I've been pondering something reading this thread. Is there a formula, calculator etc. to determine the actual depth a thread would need to be cut to given a certain threading insert (tip radius...

    At +.01" tolerance I would use a .125" tool, with 3/8 LOC and a TiAlN coating or similar, and a slight corner radius ideally (.01 to .015"). Drill a start hole, then enter that and go around .021" at...

    That... sounds preposterous. What in the world? What does the code look like? I assume you're making the thread cycle using the conversational programming.

    I was going to recommend having one programmer offset their shift if need be. That is what the company I work for did when one of our computers went down. I went to sort of a mid shift so I could...

    We use a Royal straight shank spring center, chucked by the subspindle chuck. We do use an extension for it otherwise we would not have any tool clearance at all, it's just a turned rod 2.25" O.D....

    Check with Kennametal. They will offer a tooling voucher allowing you to get quite a bit (20% of machine value I believe) for half off. I like their Beyond Evolution for cutoff, and Kennametal...

    That’s really good Bill. Glad to hear. It’s funny, from a job shop perspective things were crawling for a few months. Last couple months it explodes, then dries up, then lets loose again. Weird how...

    I would definitely recommend a Set Tru 3 jaw chuck, a plain 3 jaw is so much less useful. We have a combination 4 jaw for ours as well, used it once in two years. Changing chucks can be aggravating....

    I probably would go to 1018 or 1045, A36 is pretty gummy. It is surprising that they could deform like that though. I know OEM Haas blocks seem to be made from some soft cast junk, ones purchased...

    I'm not a fan of collet pads. We have an S20 chuck, and on smaller sizes they are quite difficult to take in and out, having to be pried out. Say 3/8" and smaller. I would go for a Royal QG chuck if...

    Tailstocks on a Haas unfortunately only have two speeds, rapid and feed, not controllable via an F code, plus they can only be positioned in .100" increments. They're really intended to be used for...

    It's funny though, our only recent experience with OSHA (and TOSHA) has been positive. But the difference is, we invited them in, instead of them being called in. Instead of fines, we were left with...

    Great news to hear, Bill. We got really slow here for about a month (just long enough for the floor to catch up :crazy: ) and then right at the end of July it seems like the floodgates opened up.

    Try roughing out just a small portion of the taper, finishing that; rough out a little more, finish that; rough out the rest and finish that. On some flimsy lathe jobs that's about all you can do.

    We have had great performance with Kennametal Beyond Evolution, using the KCU25 grade. Run on production cutting off 2" diameter. I would flood as well as try to get one with through-coolant, and we...

    For me, it does depend on the run time and how many parts there are to run. I almost always machine-deburr outside profiles, larger holes etc. so long as the standard deburring tool, always in the...

    Yep. YG1 AluPower end mills are good. I am very fond of GW alumigators as well, especially the type with chipbreakers. They will rip and tear like no one's business. They can be pricy depending on...

    Yep. Crazy, ain't it Ox? 500 miles and that big of a difference. We had a good two- or three-week stretch of high 80s to low- even mid-90s. Plus that awful southeast humidity.

    Not a teacher but I graduated a the machining course of a state technical college five years ago. Maybe I can provide some insight.

    We've used WCMX inserts from YG1, like them very much. Quite cheap, yet they perform great. I believe the grade is YG608? So far, YG's turning/drilling inserts seem to be good stuff for the price.
