Andy, That boring head is unreal and I've never seen anything like it. I'm not quite sure how it works. I'm guessing the housing the cable is connected to is stationary?
I looked at all 247 pictures you had and couldn't piece together how it works, but looks like you made some of the pieces and maybe the circuitry? Is there a motor and feedback powered through the 25 pin d-sub connector? How is the index or radial motion controlled? I like the idea of holding the work piece stationary. I had thought about a XY table w/ rotary on top, but still needed to spin the part. I have a tendency to over-complicate things... I did quite a bit of google searching for 'cnc controlled boring heads' and 'cnc radial boring head' and found a few things, but many seem to be too large: http://www.dandrea.com/en/contents.asp?c=10&s=28 (also here: http://www.tysontool.com/ecat-dandrea.htm) http://amiusainc.com/innovative_solutions.html http://www.cogsdill.com/products/zx-systems/ (looks $$$$) http://www.nickunj.com/product_inside.php?id=242 This had an autofeed, but not quite it: http://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Milling-Machines/SIEG-X3-Small-Mill/X3-Boring-Tools Mark Note: 'CNC Facing head' is also a good search. *Re: [Emc-users] OT: Grind a hemisphere or ball end on rod <http://sourceforge.net/p/emc/mailman/message/34179850/>* From: andy pugh <bodgesoc@gm...> - 2015-06-05 20:47:29 On 5 June 2015 at 21:19, Mark Johnsen <mark@...> wrote: To turn 1.25mm x 2m you would need to spend more effort on the support than on the machining. So, perhaps the best idea is to hold the work stationary and rotate the cutter / grinder. You would need a machine spindle with a CNC-controlled rotating radial axis. Here is one I prepared earlier:https://picasaweb.google.com/lh/photo/1gX6p3sVta2YivGyk8rrX9MTjNZETYmyPJy0liipFm0?feat=directlink -- atp If you can't fix it, you don't own it.http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
