[@3000gtwelder]

Yeah, I have lost a couple of edge finders kinda that way, by not remembering what RPM I had it at, and one really nice Interapid Dial indicator, by hitting cycle start with it in there by accident lol.

[@BrilliantDesignOnline]

If only you had the spindle speed set at 4999 rpm, you would have been fine :-) I am really sad that you did this, and by sad, I mean glad. Very cool to see what is inside it and REALLY appreciate your analysis of the design intent. Perhaps Haimer needs to integrate a bluetooth wireless disable feature, so when the device is in the spindle, it automatically disables the spindle by delivering a 10,000v shock to the operator who touches the green start button :-) The closing re-shot of the event was as brutal as the opening shot. And by 'we' accidently hit 'Cycle Start' you meant who ??? At least you captured it on camera.

[@mindaugasnomnom3548]

Someone suggest him what else 'we' can put in that death trap and disassemble as fast as 'we' can.

[@routercnc9517]

Quicker than using the vice of knowledge . . .

[@886014]

John if you're still fiddling with this try moving the dial mechanism within the housing. It's been a while since I've had my Haimer apart, and mine is also an earlier model, so I don't recall the specifics. However I do recall the alignment of the dial mechanism within the housing being part of the alignment process and it's a fairly simple process of loosening the screws that hold the dial indicator mechanism in the correct position and fiddling with it. It could be worth a few minutes to check anyway if the thing is otherwise trashed. I think Long Island Indicator may repair Haimers (though not sure) however as I understand it Haimer don't sell parts.

[@bcbloc02]

Jared still working there? Haven't seen him in a video in awhile.

[@Lilledritt1976]

If you do run it at 5k rpm... make sure you have super high frame rate camera catch the action ;) And another thing... if you really don't want to disassemble it by hand try running it at 10k? or 15k?

[@Raptorman0909]

It just goes to show what insane levels of acceleration occur at even modest rpm rates. I made a rough calculation that the max acceleration was about 839g's.

[@zblprojects9753]

Ah... NYC CNC... the place where accidentally destroying precision equipment is accompanied by cheerful, upbeat music and funny sound effects

[@MJPilote]

I'm curious what kind of control lets the machine start the spindle in jog mode or probing mode by hitting cycle start? Not any of the real controls lets you do that! Either it says tool error or wrong control mode and that's it.

[@laurenswijnschenk7032]

With Siemens, for example, you can start the spindle by pressing cycle start. It's not so weird.

[@summitx670]

I have a Haimer Zero Mater and have broken 2 tips but I hope I never have to work on it. But thanks for the information on how they work.

[@joshh6470]

A guy at my work turned on a coaxial indicator at 6000 rpm and the rod that sticks out to stop the rotation shot out and smacked him in his side left a nice mark and bruise but could have be much worse if it hit straight on.

[@OriginalJetForMe]

I kinda cried when I saw that! Any chance spinning the unbalanced load damaged the spindle?

[@adamsoto6466]

Rick, running any unbalanced tool holder assembly in a spindle runs the risk of damaging a spindle. Doing so will also void the manufacturers warranty on any new machining centers. Most machine builders will put a label on the spindle cover or electrical cabinet stating the balance requirements for the spindle. Something along the line of G 2.5@ 25,000 RPM or G 6.3 @ 14,000 for example. Note the G 2.5 rating is a much better balance rating than G6.3. Visit the Haimer USA website and read some of the stories on there from customers who purchased a balancer after blowing up their spindle and spending a lot of money on downtime, repair and scraped work pieces. There are so many benefits to running balanced tool holders, longer tool and spindle life meaning more bang from your investment of tooling and equipment, better surface finish resulting in less additional operations.

[@danl.4743]

[@nyccnc]

[@notamouse5630]

It would be cool if someone made a tool-holder and spindle insert designed to prevent rotation on non-rotatable tools. Perhaps a pair of mechanically balanced electrical contacts.

[@Sellutin]

Our machine has ability for clamping spindle :P

[@sylvainforget2174]

I've spun dial indicators before. It was painful every time. For years, the QA department had a trimike(mic for id bore) mounted on a plaque on the wall. Someone (not me) measured the large part in the turning centre and restarted the boring cycle with the mic in the bore.

[@JaakkoF]

Would it be possible to have a fail-safe in the machine controller, so that you can say "this tool only 60 RPM max"? Heidenhain has an input field for it, but it doesn't prevent you from programming a higher value.

[@TechTomVideo]

in your control supports encoded tool holders... yes

[@adamsoto6466]

Good job on the repair and the video! I can say that the sensor needs to be calibrated since you repaired it. That is why you are getting wrong measurements in X and Y. Haimer USA can calibrate them in house for a nominal fee and turn around is usually within a week.

[@curt149k]

That black plastic piece is not plastic. It's hard anodized aluminum. Not that I've had to take one of these apart to fix it....

[@bvcxzgt5451]

African or American Haimer?

[@AJR2208]

How does a Haimer work? - You Swaing it while holding onto the Haindle.

[@ChadHHC86]

The reason for the inaccuracy of xy measurements is may be due to no preload on the clock spring in the actual movement when assembling you should have the bezel off and put one to two rotations on the longer needle and tape it down then assemble the unit and the last thing you do is reassemble the bezel. Being you are in NY try Longislandindicator.com they are in my opinion the authority on Interapid indicators but may know a thing or two about these .

[@marianodiaz461]

Hi; any chance to share the fusion files? I would like to have a go at making one without pulling apart mine….

[@Cucurko]

I don't have that much of an experience with the Haimer, but I thought the large arrow should be pointing zero when the taster is not touching anything in order to get accurate XY measurement, or it doesn't matter?

[@Rx7man]

Since no one else has replied, I'll take my best guess when the dial reads zero in the x/y axes, the edge of the feeler is right on the rotational axis, so no need to apply any offset for tool size

[@billshiff2060]

I did the same thing but it was with a Starrett edge finder in it. Never did find the parts. That was only $20 , how many edge finders = 1 haimer?

[@phillhuddleston9445]

[@SH-pc4xt]

Interesting lesson/video! Was great to see some detail on how the Haimer 3D probe actually works. Finally got around to looking up 'Taster' in German to English translators. Looks like 'Taster' can mean 'button', 'stylus', 'feeler', or 'surface feeler'. So in German, the name makes perfect sense (no surprise there). Just seems a little peculiar in English... Also, thinking about the forces involved, I don't buy the rationale offered for why there are 8 screws around the lower ring. Sure, there are some 'stresses' induced when a stylus tip is adjusted to ~0 runout, but the forces are very small. The entire assembly in engineered so that tiny lateral forces are sufficient to move the stylus. I suspect that if you removed every other screw, leaving just 4 with 90 degree spacing, you would not be able to demonstrate any change in real-world performance. Still, I'm leaving all 8 screws in place in my Haimer 3D Surface Feeler in honor of German over-engineering. Better over-engineered than under-engineered.

[@gcewing]

I think the adjustment is performed by flexing one of the metal parts, which requires a lot of force, so the ring needs to be really well anchored down.

[@steveh8724]

I haven’t taken one apart, but the adjusting screws are tiny and adjusting them is a delicate task, not much torque required at all. So I don’t agree that 8 screws are required.

[@robertqueberg4612]

A very interesting video. The same goes for an Interapid .0001” test indicator @ 10,000 rpm. In the summer of ‘91 a tech. was setting up a Fadal 4020. Of course the door switch was bypassed. I almost got that in the face! Be safe.

i managed to crash one of these things (z crash): that rod hit the hemisphere and moved it out a little so there was some play on the z axis; the change in geometry meant the x and y were unreliable, but when measuring in the z-direction it was still accurate. figured it must be salvageable, so i had my dad look at it; he bent a pin or something inside the device so that the top of that rod seated correctly in the hemisphere. *i just finished the video*; it might still be salvageable. see if there's any play in the z direction (when you pull on the tip)

[@marcilloferente8393]

xD man, that takes stupidity to press start one the mill there.

[@drewjohnson4794]

If one of the employees decided to rebuild it, he'd be fired. When indicating a new tip to dead center of any probe like this, I like to bring the test indicator to zero and then move it off ten thousand and move it back to make sure it repeats. Only when I'm within a couple tenths though. Without doing this at each quadrant, I guarantee you are not centered. Nobody thinks of this. By doing this you are eliminating most of the built up tip pressure from all the friction. It matters if you want it truly centered. If you leave the test indicator on the probe the whole time while spinning, it'll say zero once you are within a couple tenths. Do the same thing as you would normally do, but once you think you are good move it off and back on, at each quadrant, and I guarantee you'll see additional error that came from somewhere that you didn't see when leaving it touching the whole time. The more pressure your test indicator applies the worse the error will be.
