The Tschorn is being returned. I was suspicious when I opened the box and noticed dirty fingerprints on the inside. Apparently the box was opened and the taster removed from the box. By whom I have no idea. Could have been a Travers warehouse person or a previous customer, or ???.
Anyway, wanting to see how well it worked I went ahead and set it up. Dialed in the probe tip to within .0002" TIR. I could have fiddled with it more to get it closer but I wanted to try it out. Using a 123 block in my mill vise I touched off on the left side of the block and brought it to "0" on the taster. Raised it up, moved to the right side and jogged down to the same Z height. Jogged over until the taster read "0". This where it gets interesting. I jogged off zero then jogged back to zero. Checked my X axis DRO and it was off .0015" from my initial reading. Hmmm. Moved back to the left side and zero'd the taster. The DRO was off nearly .002". I wiggled the probe in the Y+/Y- direction and the taster needle moved about .0015". Repeated this on the right side and the same thing. In order to get repeatable readings I had to wiggle the probe. Ran the test a couple more times and was able to get consistent readings (within .0005") by wiggling the probe. This is not why I bought this. I can get as close and I can do it much faster using my edge finder.
My observation is the mechanism is not as smooth acting as it should be. Not sure if this a trait of the Tschorn or I got a bad one. In any case it's going back. Anyone experience this with a Haimer?
Sorry you got a bad one. Mine ended up being very nice I’m within .0005” every time and it seems smoother then when I first got it.
