    I can perform tool change cycles, however when I do, the Z goes up and then ATC comes in as if it knows there is no tool in spindle and then Z drops onto supposed tool ( there are no tools in ATC, cuz can't figure out how to load it ) then ATC goes back home.

     

    ???????

  2. Hello All,

     

     

    I am trying to help a friend out with an old machine he just picked up.

     

    If anyone is running one of these can you let me know and see if you can help with some issues i'm having.

     

    One for sure is loading tools.

     

    I put a tool in to the spindle and cannot get it to put it away.

     

    Error,

     

    Illegal tool in spindle?????

     

     

    TIA,

  3. Hi Lee,

     

    I am located in Edmonton, and I provide consulting services for CNC manufacturing. I can help you in the future if you need. Please feel free to contact my office at 780 770 4767.

     

     

    I would be interested in talking to you about what you can offer me in the way of advice.

  4. I do have a big angle plate.

     

    Next time this job comes up I will give that a try.

     

    Motor,

     

    Not sure what a 123 block is, and yes both ends are indentical.

     

    I did manage to get my time down a bit by using a 2.2188 spade drill but could only feed at 0.15 IPM as it shook like a bugger.

     

    Problem is, customer was only paying about 90 bucks for each hole at another place.

     

    If I could get the Threadmilling down to 35 minutes might be able to compete.

     

    As it stands now, I am using a HSS Threadmilling cutter and taking two swipes with three separate depths and only running at 0.35 IPM so takes ages.

  5. Ok,

     

     

     

    so I am trying to put a hole in a piece of 4145 in an already finished bearing housing. I don't have a large enough drill so I am first going down with a 3/4 then following that with a 1 1/4

     

    It has to finish up with a 2" NPT thread for a nipple to be threaded in.

     

    Then I am contouring the rest out with a 1' roughing end mill with .15 step downs and the transition between depths in the hole so not cutting until down at next depth.

     

    The machine is vibrating alot and it seems as if the cutter is only cutting on one side.

     

    I took the rougher out yesterday to find an indentation on the holder where the taper stops in the spindle at the top, like a ridge.

     

    So i'm thinking that when it does a tool change the air is blowing crap down on the the taper and causing this.

     

    I am now cleaning tools in between tool changes to try and eliminate this possibility.

     

    At this moment I am running the Threadmill and it still seems to be running weird, like it is only cutting on one side also.

     

    I have checked the spindle at the bottom and can see no runout.

     

    On the threadmill, which is HSS and about 1 1/4 of thread, which as it starts at the bottom cuts all the threads in one sweep, which is quite a bit of load on the cutter and doesn't sound good.

     

    The firstime I did this, i did it on a test piece and it worked ok, however that piece was fairly short compared with the seven inches that the vice jaws are open now.

     

    The second one was a proper part with not much thickness to the edge, and when the rougher started to work it actually moved the job over in X and when it went for next depth there was no hole to plunge into and cutter smashed.

     

     

    Now I have clamps either side stopping any sideways movement but not clamping, just sitting there as stops.

     

    Almost got it done but had to slow feed down so much its taken me over 11 hours to complete, and apparently can only charge about an hour a piece, which is really not good.

     

    Any help would be greatly appreciated.

     

    Hope you are not overwhelmed.

  6. Hi Everyone,

     

     

    I have a FADAL 3016L and am starting to get some work for it, however I am struggling with either machine limitations or possible other issues which I could use a hand figuring out.

     

    I am in Edmonton,AB and if anyone has any working knowledge or experience with this machine I would be greatly appreciative of some guidance and/or assistance.
