3D Taster Opinions

I’ll be setting mine up this weekend on my Fadal. Only thing I dislike is I cannot leave it in my toolchanger because it’s not waterproof. But that’s ok the electronic edge finders I used to use were not waterproof either I just didn’t care about those.

I hope this thing repeats like it should.

I've read quite a bit on the web about the Haimer and Tschorn. Definitely the Haimer is the most popular of the two but both are highly rated by end users. What it came down to for me was cost; $220 vs. $430. I'm a hobbyist so price is important as long as the quality is similar. I don't have a tool changer on my mill so the IP67 rating wasn't a factor in my decision process. I've got a second operation job waiting so I'm anxious to try it out.
 
We just threw out about 15 haimers because the operators at work seem to crash them a lot...too bad there is not anyone locally to fix them....

I wish I could got a couple of those.

Anyways I got my tschorn all dialed in and some far it’s looking decent.it doesn’t seem to have the smoothest action and almost seems like it gets hung up. But it not that bad and from my quick testing it’s quite repeatable. I haven’t had any chance to play with it more as I’ve had a job cutting for the past 2 days straight and I don’t want to get in the way of production to test this thing any further.
 
I have had the Haimers stick, I just go to the crib and get a new one when I am checking a machine. The old one hits the scrap bin because no one fixes them and they are not that expensive for a Big CNC shop...you would not believe what they threw out in carbide milling bits, reamers and cutters, just because the work statement changed and they may not be used for a while and it costs too much money to keep them in inventory:frown:

Crazy well I’d like one of those broken haimers if you get a chance. Sad they throw that stuff out I pay good money for it.
 
Has anyone tried to get service on a haimer. Their company is pretty close to me in villa park IL. I’ve also been on the hunt for one.

I looked on the Long Island Indicator site and their only reference to Haimer is that they are a specialty device and repair parts are not available so they must be sent to Germany for repair. Same comment for Haff and Schneider.

Haimer doesn’t care about the little guys at all. All of the 3D sensors have to be dentro Germany.
 
I did check with Haimer as to repair process and it is a long process and potentially costly. Still, I am very happy with its performance and accuracy, I did break the tip once, so I am more careful with it. Drop it on the floor or crash it hard, that may be another story. The Tschorn are comparably priced, the SavePlus version is significantly less expensive, they are also available in 1/2" shafts vs. the Haimer which is either 12mm or 3/4".

Haimer repair process

Receive an RGA from us, and send the sensor to HAIMER USA, ATTN: RGA#, 134 E. Hill Street, Villa Park, IL 60181. We would need a $0.00 PO in order to track the unit overseas, and most people just put it in the box with the sensor. We cannot send anything to Germany without a PO.


2. Once we receive it, we will inspect the unit in house first. If it’s something simple, we will quote cost accordingly and repair in house. Please note that this is generally only in the case of recalibration; if the unit has been crashed, it cannot be repaired in the US.

3. If the unit is going to Germany, we will send it on our next return shipment (every other week).

4. After Germany receives it, they will evaluate it, and send us a quote on the repair costs (usually takes about 1-2 weeks for us to receive the quote).

5. Once we receive the quote, we will quote you that cost. If you’d like to repair it for that price, you’d approve the quote, and that cost would be added to that original PO. Germany will then repair the item in about 2-3 weeks, and ship it back to the US.

6.
Once Haimer USA receives the item, we’ll call you for the credit card information, and will charge the cost of the repair, shipping from USA to you (if not shipping on a collect number), and a 5% transaction CC fee. After payment has cleared, we’ll ship the item back to you, and the PO would be closed.
 
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?
