Hi All:
My business partner is looking very seriously at a UMC750 SS as the newest addition to our shop.
The Haas sales guy is talking up the virtues of the machine with great and florid enthusiasm, and I have to say, there are some nice convenient features that come with the machine, all of which have been declaimed about in loving detail.
Any of you have one?
What's the real deal with these; are they "good" machines, "OK" machines, or "crummy" machines?
The little bit I've found online on the subject has not been super positive, but so much of it sounds like the "Haas Haters" going to town.
On the other hand, I was at the local open house with demo, and the machine sounded great cutting 6061: then it was asked to cut a chunk of 4140 prehard.
I didn't much like the noises it was making chopping through that lump; I got the distinct impression it was not as tight or stiff as it needed to be to make decent time in that material without wiping out a lot of cutters.
The part was maybe 4" diameter and fixtured so the top was a foot or so from the table surface.
The cutter was an indexable, something like a Sandvik Coromant maybe 3/4" diameter.
I realize this is all hopelessly vague, but I'm looking for impressions as much as specifics.
Any comments will be welcome.
Cheers
