CMM-Ve Accuracy

Looking to purchasing the CMM-Ve for our B&S One CMM with a Tesastar-M articulating head. We work with tolerances as small as +/-.0002" and I need to know if the CMM-Ve is a good option for us. I wanted to ask an opinion from someone other than a Hexagon engineer (who will obviously praise the CMM-Ve).

Thanks for the input and advice

Thanks, I appreciate the input. The typical tolerance that we deal with is +/-.0004" which, as far as I know equals to a capability of [(.0004 + .0004)*25.4]/4 = .005 mm which is reasonable (U = Ttotal/4 as far as I know)

We do get the occasional +/-.0002" but I guess that is a little unreasonable for even a TTP with a rotating head.

I would probably use the CMMv only in A0B0 though, because I don't like to rotate my wrist even with my SP25 Scanning had because I feel like the accuracy goes out the window (though it is repeatable)

Thanks again
