I was looking at getting a trunnion table. I'm new to milling and trying to mill wax for jewelry. And I was looking at the HTS table and a couple of rookie questions came to mind as I looked at it and thought someone here could shed some light into the dark cavernous region on my head:
1) why is it a 5 axis table? Table rotates as axis A, second table as C... But if A rotates 90° then second table is B axis. Is it because only 5 axis are "in play" at one time (xyzab or xyzac)?
2) and the HTS has it's second rotary table positioned above the A axis. I would have thought the physical table would need to be below the A axis. I thought the whole setup procedure was to get a perfect xyzabc point. Or is that a virtual point and your work piece can reside in any location within the working rectangle and your cam software calculates the off center differences.
