Dave,
Thanks for the info.
First, I thought nmtb40 = ct40 = 40taper = #40. I have heard and read the taper is the same, I guess somewhere along the line I equated them.
Next, where I work we have a Leadwell kmc-5p(5hp), and mvc-1000p(15hp), Gorton 2-30(5hp) and a few others. Any of these machines would remove material fast enough for what I need to do and I have cut steel/aluminum/stainless on them without issue. With the right endmills they could remove material alot faster than I have ever needed them to. I have no problem with more than 7.5hp and would love a 15hp machine, but most I see run around 10 and most of the knee mills run around 5 so I just ballparked 4 to 7.5 for what I feel I would actually need.
30x 15y is the approximate work envelope I would like, not the part size I need to machine. Most knee mills I look at have comparable travel to this and the VMC's tend to have a more square envelope which is fine. I can trade a little here and there. To be honest, I have never had a part I needed to machine that I could not do on the Gorton and have plenty of travel left, but if I am going to spend money on a machine I want some extra "just in case".
Still looking for more input
Thanks,
