“Even when companies can go to one of our competitors, they come to us because they know what they’re going to get. That makes us always focus on quality, which means everything we send out has to be perfect. I personally check every machine that goes out. It’s not like this is something we only do to make a living. This is something we do because we actually enjoy it, and we take a lot of pride in it.”

” 3 operators measuring with Mics and pins vs the Unite-a-Matic.   All I can say is there is no way three operators measuring with micrometers and pins with come close to being repeatable or ever pass a Gauge R&R.   It was a complete fail as the results were all over the place for size between the operators.   The Unite-a-Matic takes away the operator.  It is very accurate and repeatable and I think a must have for when you need to control the size consistently.  “

This is my experience and I think you will find it to be very useful.
