Yup, that was the big drawback I saw.  Every kinematic arrangement has its pluses and minuses.  When comparing to 5ax to 3ax it's pretty interesting how quickly kinematic arrangement becomes hugely important to getting the best results, whether it be quality, cycle time, or operability.

Thanks for all the replies. A real downside to this setup for us after talking with Makino today will be that we cannot get to features that you would typically machine on a trunnion at 90+ degrees. No setting up a pyramid style fixture with 3 or 4 vises that you can machine 5 sides of multiple parts at a time. The kinematic arrangement just doesn't allow it.  

Now is not the time to be learning this. That should have been the major thing considered before every getting the machine. That said don’t always trust what you hear prove what you know by proving what will and will not work. I could do a lot on that machine that might suprise a lot of people.

Our Makino sales guy is talking to us about this machine. I don't understand the advantage of this layout over over the D500. I suspect there is none.

Pallet Changer?

There is a huge difference is machine dynamics and tool change time. 

Machine cost is significant different as well.

THere is an optional pallet changer for the D500.

I'm sure it's quicker since its looks like it's on an A81 chassis. I think unless it's in the 500k range they are going to have a real tough time selling those.

They have their place in the Makino lineup. A lot of times Makino is adding a 5th axis to their a51/61 lineup for the production machining side of the their business. From talking with them on Monday, when they use that configuration for high volume applications they are only going to B 90 degrees to hit component features. This machine eliminates the added 5th which is typically a higher total cost and longer integration. One of their direct competitors in this space and the semi conductor space is Grob. Large volumes of machines in an automated cell and high removal rates. From my understanding this machine has significantly higher dynamics than the Grob lineup and is much more robust from a pure material removal standpoint which stands to reason based on its kinematic arrangement compared to Grob, virtually no overhangs. The a500z is build on the a61 platform.  You're not far off on price. Consider vast majority of the parts for this machine have already been time tested on the a61nx and literally they aren't any different than the a61nx. Only something like 15% of the parts for this machine are new items for production and support from spare parts inventory. That's a BIG deal when bringing a new machine to market.
