To DMG-Mori a $220K basic universal is their "Entry model", a $300-$600K universal that can swing about 800mm is classed as a "Good all rounder" (in their words), and then you get far more specialized "linear" machines that start at 0.5 million and keep going (not including duo-blocks etc. Because that undercuts their main 5 axis universals such as the DMU 50, or DMU 70, or new dedicated trunion style machines such as the DMU 65 Monoblock, and many many other models. DMG MORI don't really want to make it super easy for their customers to do relatively high quality 3+2 or sim 5 axis on a $80K three axis mill. They sell a lot of those but the 5 axis arrangement with the Lehmann is not ideal/ is a weak solution unless lower tolerances and surface finishes are permissible. So as I say they offer up the Lehmann at least for four axis work (on the CMX platform as you know) which is adequate for some applications (not as good as the DMG Mori DDRT 4th axis rotary.
I think what you may not be getting here or picking up on is that DMG Mori does not make a twin supported trunion of their own (as far as I am aware) and things may get "sticky" when they are not so willing to support other 3rd party trunions that YOU might like to run :-) (depends a little bit what support is like for you Locally). Normally the DDRT 5ax would be used on a much more powerful and robust 3 axis mill like a DMG Mori NVX 5100 (remember the DDRT 5ax unit weighs over 500lbs and that is not useless mass for the sake of it).
that is why I mention it to you as you are trying to achieve 5 axis positional work on (3+2) on their most basic DMG Mori 3 axis mill. I said the DDRT 5ax is more rigid and precise than the lehmann 5 axis offering, Which it is and I am saying the DDRT 5ax is sufficiently well engineered (Mori Seike in Japan) rigid, precise, fast and sensitive enough to do exactly what it is designed to do (assuming one is not reckless). I did not say a cantilevered system is necessarily more rigid than a trunion supported at two ends. You are kinda twisting what I actually wrote. I'm leaving for Pfronten on Friday and will have some news on Monday. I think that we have significantly digressed from the original goal. I don't even know if someone has a real "CMX ABCD V" in production and what do they think of it. Sigh!!! This thread was to get opinions from real life usage of these machines and the options that are available in the industry including modern control systems.
