Ok, this might sound like BS, but I honestly question why we need the super rigid machines* - box ways and million pound castings when modern cam lets you do so many different varieties of HSM (high speed machining) techniques? I mean, in the 'olden' days (LOL ) when cam wasn't as prominent, and making the code by hand fast and accurate and compact, sure it would be much easier to program that slot / cut burying the cutter to minimize programming time and code lines / size. But why now?
I can sort of see with surface finish, but I thought that was more related to tool holder / and cutter runout and geometry, and processing speed-look ahead of the control..?
The reason I thought about this was all the recent Haas bashing about not being able to take a cut and all that stuff... I've run mostly Haas, with a smattering of Robodrill (30 taper so a different animal IMO), and Mazak and some old china type iron.
When I was in a job shop we cut tool steel, 4140ph, and hardened toolsteels all the time with Haas machines. Maybe not as fast as some other high end machines, but very doable, and we were loaded with work mostly so apparently we did ok on our quoting and making parts... We had an SL 30 that ran 4140 10-12" diameter blanks all day every day. We made good money on those parts as I recall. These were big enough we needed a crane to get them in the machine, and light enough when done to unload by hand so we removed ALOT of material (in a timely manner if I say so, but I don't have a metric to compare it to...)
We made alot of the flywheel portion of these (in our Haas SL30 and VF2-3) , but unfortunately not seeing any good pics of them.

edit: before tom shows up to tell us we are running toys, I am more specifically talking about the general ranges of 40x20 machines
