    Also called interrupted taps, Emuge makes them http://www.thomasskinner.com/default.aspx?page=item+detail&itemcode=EMU-B01210010080&catlist=3338

    yes, Also Helical flute taps put less pressure than straight flute as well.

    you might want to see if there are skip-taps for that size. I know we had an issue like this and it was fixed by using a skip-tap.

    http://gsi.nist.gov/global/docs/vps/csfiles/cs_24-30.pdf Try that, otherwise I would send the gage to a calibration company for them to calibrate the gage and certify it to UNF standards.

    Here is the way we do it, this works for 4 digits but can be adapted for 8 easily #501=FIX[#101/10000] #502=FIX[#101/1000] #503=FIX[#101/100] #504=FIX[#101/10] #505=FIX[#101/1] G4P1 #505=[#505-[#504*10]] #504=[#504-[#503*10]] #503=[#503-[#502*10]] #502=[#502-[#501*10]]

    Jeff, We have one lathe that cuts this steel 24 hours a day. Try roughing 330sfm @.01 per rev .1 depth of cut. Finishing 400sfm @ .005 per rev. Seco CNMG 432-M3 TP1500 inserts work great

    as far as multiple parts check out speedgrip mandrels, specifically: http://www.speedgrip.com/speedgrip_cameron/publishsite/index.cfm?pagename=mainpage_template&client_id=speedgrip_cameron&tablename=news&link_id=11322316&linkname=Sabertooth%20Expanding%20Mandrels

    Thanks Mark, we are currently trying parlec and techniks. both seam to leak a little with 250 psi.
  10. specv
    Ok guys, we only have 250 psi coolant through spindle on our older machines and we are looking at getting new machines with 1000psi coolant. We have purchased sealed ER collets/nuts for some jobs and we still have leakage ( with 250 psi). My question is what brands or collet system are the best and what brands (systems) to stay away from. TIA

    in order to calculate them we would need to know the size of each datum hole and the tolerance for each. an example would be if you had a +.1 size tolerance for each datum and they were at largest diameter you would gain .1 position tolerance for each feature. So in that case you would have .1 (datum E bonus) + .1 (datum F bonus) + .15 (34mm hole bonus) so you would have .55 position tolerance. You don't get any bonus if your holes are all at the smallest size(mmc) so your deviation would be .2.
  12. specv
    So when those datum features are at their smallest(mmc) that is the tolerance, if they are all at their largest you gain your bonus position tolerance. So you need to factor in the size of each datum hole called out to figure the bonus tolerance.

    This usually happens when a program was created on a different computer that is using a different NC file path, or over different versions of MC.

    Well I had meetings with all three companies, of course they told me that they all interface well with zoller and mastercam. So i am getting reference companies to talk to to see how well they work.
  15. specv
    Im guessing this is a blind hole. could you make a carbide extraction tool from apiece of carbide? Eiher that or use a left handed drill, it should bit on the first coil and spin out.
  16. specv
    JLW, Try these guys, http://www.bluco.com/large-cnc-fixtures/ their stuff is all modular, we have quite a bit of the smaller stuff.
  17. specv
    Is the roughed hole round? I think that may be the issue, also you said you mill it within .005 is that total or per side.
  18. specv
    I am currently talking to all three again, Zoller, TDM and Wintool. Daniel, so the zoller interface does not even work right with wintool or just a pain to implement? I need both MC and Zoller to talk to this system, maybe i need to check zollers interface again.
  19. specv
    http://www.ingersoll-imc.com/en/products/BRO-034_Plunging_Cutters.pdf They have cutters down to .375 Seco has mini-masters down to 6mm diameter as well.

    If you want x,y moves then you need to change your rotary axis control to "no rotation" it was set to "Y axis"

    I got the same screen htm01 got, Ben's link worked for me, Thanks Ben.
  22. specv
    There is nothing there to download for x9 am i missing something?
  23. specv
    Matt, Call PQI they have them for calibrating probes. http://www.gagesite.com/inspection-probes-c-510_511-l-en.html
  24. specv
    This is exactly what we do here, the toolcrib guys get +/-.04 from the gage length value (simple to do with a presetter), otherwise the machine alarms out.
  25. specv
    http://www.ktoolinc.com/k-tool_doc_120.htm or what Ron suggested, but with that set-up you'll need 20+ cutters
