You could buy that head and mount it on your first prototype machine then work the bugs out and use the machine to manufacture your own 5 axis head with improvements that make it better than the one you bought. Question??? how are you going to focus a laser beam on a 5 axis knuckle head, because a fiber optic cannot carry enough watts to do more than cut up soda water cans. If you mounted a machine spindle like cat 40 or cat 50 then you could build special tool holders to mount an oxy fuel of plasma machine torch in the center and make it program just like a spindle with an end mill in place, it would be really cool.then just swap torches as needed for the job at hand, you could even machine step pockets or islands for a large pump and motor package and then switch from milling back to torching and burn the perimeter out. What size of work envelope do you plan on making the machine? Will you be able to market such versatle machine for under 100 grand? I hope so.
