Review on HAIMER Universal 3D Sensor Version by Jason Camarillo

Very good tool, but without English instructions. Written by a person whose native language is not English, therefore idioms and words do not translate well. Also, the runout zeroing instructions almost certainly leave out that you must loosen the socket head cap screw (SCS) in the shank just enough for the four opposing screws to bring the eccentricity ("concentricity") of the head to zero (DO NOT EXCEED TORQUE) . . (I had to call the factory to make sure I didn't damage the unit). According to the factory, the torque on the SCS shaft should be 6 Nm or 4.4 ft-lbs. I would say less. After re-tightening the SCS shank, remove all four opposing set screws and CAREFULLY zero runout. Do not use set screws to move the head. Use your hand to move the head relative to the shaft and tighten the set screws to lock the final adjustment or you'll be fiddling with runout for (literally) an hour. The head is very finicky during this zero-run zeroing process: when you tighten the set screws, it moves more than you'd expect. Consequently, my first session took over 30 minutes before I could feel it. Once you've entered it, it's a very fast and accurate tool for finding edges and corners in 2D and 3D respectively. NOTE: There is a large 8mm ball at the end of the long probe. This is required due to trigonometry of how the crown acts on the dial indicator. My point here is: don't expect to crawl deep into a tight hole to find the edge. The geometry that makes it a fast and accurate 3D tester also makes it incapable of doing this type of probing. I don't know how it would work in a tool changer. I have a bridgeport with Maxi Torque-Rite and it seems to handle several of these cycles without a hitch. Other reviewers seem to have mixed results with tool changers beating it out of zero runout. (I agree with one reviewer who says it's easy to mess up the gauge.) To do this, highlight the tool holder/shank, clamp it, then zero runout. Check the eccentricity regularly. Once you get the hang of it, resetting is easy.
