This all has been very interesting. I have learned a great deal and realized just how much I do not know. Balanced tooling is one of them.
I did not make it very clean that I am not a NUMBERS production shop. But a research facility making prototypes. Finish, accuracy and 3D profiling are very important. Versatility is a major factor.
My love and interest for the trade is enormous. It is going to make some interesting reading. Now to look up "balanced tooling"
The department is leaning toward the Super Mini Mill 2. Thanks to this hearty discussion, I am going with the 10,000 rpm spindle. I already have to take the sheet metal off to get inside a 54" wide door. Other limitations include an elevator with a 5,000 lb weight limit and door 84" high The design of the building is very limiting.
Thanks again for all the help.
