tormach limitation, or am I doing something wrong?

FWIW,
I bought the 3/4" Shank Haimer and ran directly in the R8 collet (no toolholder) with no issues staying within a few tenths . It was also nice to have the shorter gauge length.

Are you tightening the drawbar when using the Haimer? Do you need to tap the drawbar to release it?

I do tighten the drawbar, but not so tight that I need to tap the drawbar to release the haimer out of the spindle.

Did you put a collar on it so you could use it for height offset as well?

I had pdb, so it was tightened like any tool holder.
Shouldn't need to tap it if the r8 collet is lubed on the outside taper.

No need for a collar, just the Haimer. Height was set on the tts granite block just like all tools.

I think that his question was in relation to your usage of the Haimer to set Z-height of your stock. In my experience a tool with a 3/4-inch shank and flat top for the tool will vary slightly in Z location since the top of the tool rests on the R8 collet rather than on the spindle nose. I once tried to use a facemill with no TTS recess on the top. I eventually determined that the variation in tool length was of a result of how tightly the collet closed.

I had this problem with Haimer and the TTS holder for it. The concentricity of the tip always go off by +/-0.01mm after a while, but not immediate like yours did.

Unfortunately I don't have good news for you as I have pretty much given up on my Haimer. I use the Hallmark ITTP now and that has been a great piece of equipment.

I hope you will find a solution for your Haimer soon.

If your Haimer is off by .01mm, I wouldn’t even be concerned. That’s only .00039 inches. That’s less than half a thousandth of an inch. The machines aren’t even that accurate. If you need better accuracy than that, you probably bought the wrong machine.

Hey everyone

I recieved some goodies in the mail today. I got the new tool holder, but I also recieved a new generation model haimer and tool holder for that I purchased.

I quickly went straight to calibrating the new generation model.... once calibrated, I took out of the spindle, put back in, and wouldn't you know it it repeats as it should!!!

I did this probably 20 times to make sure I hadn't lost my mind. It repeated every time!!

I WOULD LIKE TO THANK ALL OF YOU FOR TAKING THE TIME TO TRY AND HELP ME, ITS GREATLY APPRECIATED!

I guess I had just got a bunk haimer?!? But my new generation model works...and so now I am happy!

Awesome! The fun begins, I think you will find your Hamier a handy very precise tool. Quick tip the dial always turns clockwise moving into the probe tip. I keep that in mind and rarely break tips. After reading some posts here and doing some checking I decided to order a new 0.0001 indicator so I can get as fussy as everyone else. I spent an hour today aligning a 3 jaw chuck on my 4th axis. Fixtures and tools require a fair amount of time just to setup and use and or change out . And every little thing comes back to bite you somewhere big or small so it pays to check everything often. .
