Hi,
This is my first email in this forum, have been lurking around for a while tho'.
We purchased a 2001 vintage DMC103v Siemens 810d from an auction in Italy, and then we fixed it up completely. The spindle was replaced, the guides and ball screws were just cleaned and oiled since it didn't have noticeable backlash. Now after using it for a year, it does, and that pains me. The backlash hurts the most in things like drilled-reamed holes. So the options are fix this machine by new/repaired ball screws. Get tool offset and part probing installed, which it does not currently have, and then attach a trunnion of either the CNC type or something like touchdex. I was offered very good money for the machine in December, so something makes me think that this could be an option.
The other option would be to replace the DMC 103v with a new CMX 1100 V with a 5 axis trunnion on the side of the bed. Sometimes we do need the long table and I'm thinking of the option to remove the trunnion for those occasions and then put it back on, for normal work. As everyone in for a new machine, I've browsed almost everything on this forum, including several negatives regarding the DMG-MORI products.
Our main work is related to prototype parts for light aircraft. Most parts would benefit from a 5 axis added trunnion, since they are usually complex and small, some others are very large and would be done without the trunnion on the bed. There are many places where we have holes deeper than 5-7D and I would like through spindle coolant for that. For parts that are made from steel and tough alloys (15CDV6, 4130, 4430, stainless, TiAl), I'll like Minimum quantity coolant/airblast. In Italy, the most used tool holders that are also rather inexpensive are DIN40, of which I already have a fair amount, so the spindle should preferably have that. I'd like to specify glass scales on all axis for long term precision and for in-machine, post work part probing. I'm fairly technical hands on mechanical and aerospace engineer, but I don't have experience with the newest Fanuc/Heidenhain/Siemens controls.
With this in mind, here are some of my initial questions:
Thank you in advance.

With this in mind, here are some of my initial questions:
- Which control would you suggest would be best for my purpose?
- Which one of the controls is easier to configure, connect to, extend etc.
- Which one of the controls can handle 3D paths better?
- I'd like to perform lights out manufacturing, would you suggest a Blum like tool probe or something standard could do the job equally well?
- Have you seen the location of part on the Haas UMC750, in which the controller has no issue in setting the part axis away from the trunnion's axis, does any of the above controllers have such a feature?
Thank you in advance.
