First of all thanks Gerald and Mike for this wonderfull forum, it allowed me to build the machine I always dreamed.
Based on the plans provided I extrapolated dimensions so they can be used with large granite slabs produced by a local company, biggest in Argentina.
These granite pieces are usually cut to be managed by small size machines, but when I managed to start talking with the VP of engineering of this firm things got wild, they asked me if I wanted to be a contractor for their newly created large slab division (LSD for short)
The LSD provides granite pieces for new luxury buildings, big $$$ if you ask me.
So a few months back I started to draw a model in SolidWorks, its size would be: 15.3m x 11.4m (50.2 x 37.4 feet for you inch ppl)
Here is a render of such a beast:

Moving such a beast was something way over my head, so I asked the local Fanuc people (a division of General Electric) they told me they can provide a solution based on a new breed of redcap servo motors (google (http://images.google.com/images?&q=fanuc%20redcap)) their new flagship marooncap(TM) ferrofluid servos
The marooncaps are capable of handling without reduction (reductions won't work in this environment) the awesome force of 1850Nm or about the force of a rural truck, more about the motors later.
The 35 HP Spindle, weighting "only" 150Kg (about 300lbs) is capable of cutting 25mm granite like a hot knife to butter, custom manufactured by an US company, SharpCustoms, its capable of running at 15000 RPM, imagine the 75Kg axis rotating at this speed, its frightening.
The electronics, provided by Fanuc, need a lot of power, thats why we asked the power company to install a small substation capable of delivering 500A peak and 350A continuous current, this is being built as I write in a specially prepared basement.
The base frame, weighting only 4Tn needs concrete floor, thats already in place, so no problems here.
Phone just ringed and I have the Fanuc people asking me some specifics about my marooncap needs, I need to answer before the long easter weekend, will post more later.
Thanks for looking, comments welcome of course!
