This is kind of long, but the two questions I have is how is the spindle being supported on the UMC750 and is the current VM3 different from previous ones?
It was the usual Westec with far fewer machine tools. The sual stuff at Haas's booth except for the SL10Y and the UMC750.
I've seen short video of UMC750 on youtube, but the one at Westec looks more like a production ready machine with full enclosure and a supported rotary table vs the catilever design of the prototype.
Though I wonder how is the spindle being supported if it has a 22" travel on Y axis? I was in a hurry and there was a mob of people looking at it so I didn't have chance to ask the Haas tech.
The other thing I noticed was that the VM3 demo looks a lot better than the ones I've seen in the previous years. I don't know if it's because of the tool path or something else, but the end result has very little tool mark and no gouges, unlike the previous demos I've seen. The Haas tech said the new one is better but can't really quantify why? Is there an improvement to the spindle? controller? servo? casting? or was it because of the demo, ie different shape and tool paths? (The VM3 was cutting an abstract shape rather than an actual regonizable model, ie game control pad)
