I came across a nice, if perhaps too general, 2-part discussion that begins with http://www.moldmakingtechnology.com/articles/part-i-spindles-and-their-relationship-to-high-speed-toolholders They don't show any examples of the kind of tooling system you seem to have in mind nor do I recall seeing anything in my random walks around the web. You might try posting your query over in the CNCZone too. Once you've settled on an approach I hope you'll provide pictures for the rest of us to ooh and aah over :-) Regards, Kent ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
