Boy, lemme tell you, you pay mightily, in the 4th axis, production-wise.
6 tool changes per piece, with NO amortization of the tool-change time over multiple pieces.... Never really thought of this, until Heinz Putz emphasized this so strongly in his programming videos.
AND, altho the fadal 4th axis itself seems robust, the snap-handle collet closing system seems to leave a little to be desired. Sometimes you gotta crank the collar as well as the handle to change pieces, which is real effing pita.
BUT, You get nice pieces. :)
Bring yer coffee, tho. :(
