    I felt the same when I first started out. I tried to stick to "generic" geometries like CNMG or APKT. I ended up with some proprietary cutters, like the Sandvik coromill which uses an R390 insert and...
  2. What's the profit margin on carbide tools?

    I think there will be a lot of variables like sales volume, rebates, etc., but what's a roundabout number for profit margin on higher end carbide inserts and end mills? Are the small, independent...

    Thanks! That worked. Funny, because the Fanuc tech asked me about 9921 also and then dismissed it.

    It's set to 0. The entire line is 01110000; this is what the Hardinge build sheet had on it and it matches the machine.
  5. "Improper G-code" alarm when using G71 on Fanuc 21T

    I used to run this exact program on a lathe with 0T but on my Hardinge Cobra with 21T control I get a #10 Improper G-Code alarm when using canned cycles. I've looked through the parameter manual and...

    I found a used drive on ebay and that fixed the problem. I would try to find a local repair facility that can look at yours.

    Thanks guys. I'll have 2" of stock to clamp onto in the vice so it shouldn't move. For the open pockets I'll try a nice sharp HSS end mill. I'm taking material off the top too and I think I'll try my...

    Without getting into custom tooling, I'd probably drill, bore, then use a full radius 90° groover to get most of the sphere and then use a small VNMG to finish the far end where the groover doesn't...

    Tooling for milling UHMW

    I rarely run anything besides steel so I'm not sure what the best approach is with this. I need to hog out a bunch of material in UHMW plastic, about 2" deep. My first thought was to use a square...

    ISE came through big time! $45 and an hour later I'm back in business. I almost can't believe it was this easy... I'm waiting for the machine to start smoking again.

    Thanks, Chip. Those guys are only a mile from me! Heading there now.
  12. Looking for a Cleveland area circuit board repair shop

    Kind of a long shot, but I had a capacitor blow on a board of one of my machines. Rather than shipping it to a repair place I'd like to find a local shop or tech that can repair it. I'm having a hard...
  13. Identifying inserts for an Ingersoll insert drill.

    Anyone know what inserts go into this? And insert screws? Ingersoll A11204521RS1 01127-L. Their website hasn't been any help for this relic.

    I shot off an email to verify the tolerances. They also want .0005" profile tolerance of the machined flat surfaces after welding so I think this maybe be a bit over-engineered. I believe the bores...
  15. Holding .0002" position between bored holes.

    I'm trying to come up with an approach for this. It's a stainless steel weldment, about 12" long x 6" wide. I will need to put in the 3.5" hole on each end, starting from solid. The hole size...

    My experience is limited compared to a lot of people here but I've had good luck with Tungaloy. In addition to the grades you need to be looking at chip breaker geometry also. Even for my small shop...

    Hmm... I see what you mean. How would I format it to actually get alternate flanking? Z start point between each X DOC?
  18. Alternating flank infeed with G92 threading

    Fusion 360 has an alternating flank infeed option and I have it posting thread cutting with G92. Does G92 support variable Z position starts? I want to try this but I'm using customer supplied...

    I think Hardinge sent me instructions for a 42 not a 65 so the reference distances are wrong. I found the right ones in my manual. Gonna give it a shot...

    Check out Fusion 360. I haven't used it much yet but from what I've seen it's great, and not just because it's cheap.

    I'm making some progress... chuck now works. I called Fanuc and they had me change KWORD K17 which allowed me to then modify the DWORD for the chuck. The only K words I've changed are the ones...

    I finally got a call back from Hardinge and they emailed me the parameters. So I got that in and am now in the process off referencing the X and Z axes, but I can't get the chuck to open or close....

    The problem with providing cost for work after the job/consulting is done is that most companies' payment systems don't work like that. They need a cost to put on the PO before work starts,...

    I was in a similar situation as you; left a cushy engineering job to take over a stagnant shop but with a solid customer base, and grew it from there. In my experience there will be some exceptions...
