Adam Savage's Favorite Tools: Haimer 3D Edge Finder!

Adam recently purchased a new tool for his milling machine that has radically improved his workflow efficiency: a Haimer mini edge finder. To explain how this gauge works and why it's necessary for milling operations, Adam dives into a thorough explanation of the ways of measuring and calibrating tools from table saw to mill, how a device like the edge finder can speed up repeated operations that are prone to error.

I'm a machinist for almost 30 years now.. i have used them all.. Wigglers, Haimers, the electronic ones, and also 3D touchprobes on CNC machines.. , on a CNC i prefer the 3D probe above all, though the Haimer comes a close second..
Lever gauges are also very versatile.. i have 3 of them in my shop, one for every machine... need to buy a 4th one, as i have recently bought a new lathe.. :)
I never had issues with "doin' the math, as you need to do that for every mill you use as well..
(the Haimer is also a great tool for centering in holes if your DRO has the Half function.. and if you want to be really precise, use a lever gauge after that.. put it in the spindle and rotate by hand.. if the needle doesn't move.. you're centered..

I have the slightly bigger Haimer 3d Taster and it's my absolut favorite tool for my manual Aciera F4 mill. I use it to measure work pieces too, and dept of holes/steps, centre of circles etc etc. I also can't understand how 99% of manual machinists don't use one or don't think it's worth the investment. Madness!

You didn't mention that the Haimer can also be used to find the center of holes or round stock, almost as easily as it find the edges. Thus, it can also take the place of a coaxial indicator, and those are not cheap devices either. So you can eliminate having to buy a coaxial indicator if you get the Haimer

You do know that they make DROs for tablesaws, right? Readability to 0.001, lengths of up to 6ft+, and reasonably affordable - from under $100 and up Have one on my Delta Uni-Saw (Wixey DIGITAL FENCE READOUT MODEL WR700) and would not do any cutting without it.

Do you even realize, that you kinda convert imperial to metric by using thousands of an inch, because imperial is just too complicated to work with? I love America but I'll never get why someone would still measure in thumbs and feet and so on🤣 hey lets cut 1 foot and 7/16 and add 3/4... (no offend) Btw, I'm gonna get myself one of that 3D Edge finders, thanks for the video👍

Here's a cool tool. Check out Kaka Industrial vise break die on Am_zon. You will need to fine tune it : enlarge the punch radius edge over a diamond stone, shim both parts for vertical lineup, reface the die front edge so the work piece sits properly against the tool and parallel to the punch edge. But what a great tool to have. I would say up to 1/16in mat'l can be bent, steel or Al. Bending radius vs thickness need to be taken in account from a proper chart.

Hell. I'm not a machinist at all, but I'm really excited about the time/labor saving benefits of your Haimer gauge. Specifically for someone who lives in an area that is world renown for the fact that the Earth moves regularly and precision consistent edge can be a significant issue when your machines get bounced around a bit.

The shaft of the Haimer edge finder being metric has to do with the fact that the company is headquartered in Germany and they tend to avoid anachronistic units of measurement. Whenever I hear imperial units the video from Orange County Choppers pops into my mind, the one they trying to find the difference between two lengths.

@12:00 ish - setting the edge. Every DRO I've used allows you to enter the dimension. So you wouldn't need to zero, then move the table and zero again. You'd just enter 0.1 on the keypad.

@13:16 When using the metric edge finder, SWITCH THE DRO TO METRIC. Then you'd not need to do any conversion maths yourself.

For UK people: These gauges are about £300.

What you forgot to mention, is that you actually need to calibrate the Haimer, using a dial indicator first, before it's of any use for dialing in your workpiece ;-) Good video on explaining the merits of the Haimer. I actually bought one as a birthday present to myself to use on both my manual and my CNC mill. It's one of those things you can ponder about for ages, but in the end you just have to take the plunge. In contrary to what you said, I've never seen it as a "mainly CNC accessory". Instead I'd say it's more of an upgrade to using wigglers. On CNC equipment probes are the way to go (and again a lot faster than a Haimer)

Adam doesn't tram his mill vise correctly, he trams the top surface of his vise jaw. Tram where you place your parallels. Also, $400 isn't spendy for quality measurement equipment.

Jonas Latza

I hope somebody can help me understand a question I have. I think I do understand how the gauge shows 0 in relation to what it touches. But I can't seem to understand how that relates to the cutting blade... I thought that the diameter of the blades does change with each one and the gauge shows the midpoint. Don't I have to subtract half of the diameter of the used tool to get it exactly on the edge of the material?
I am no machinist, but I'd like to understand this better. Thanks for any answer.
Jonas Latza
Jonas Latza - 20 dager siden
@highpwr Thank you very much for your answer.
highpwr - 20 dager siden
You are correct. Edge finding is based on locating a point that is referenced to the CENTER of the spindle. Even after using the 3D gauge you STILL have to offset the spindle by 1/2 of the diameter of your tool to get the cutting edges of the tool over the same point. The 3D gauge only saves you from having to calculate half the diameter of a standard edge finder probe _in addition_ to calculating 1/2 of the tool diameter to locate the cutting edge.

I have to point this out: Using that tool in a collet robs it of quite a bit of its usefulness. if you permanently fixed the tool in the collet you also have a known distance between your spindle and the surface you are indicating in Z.
If more of your tools are of fixed length in their holders you can use that surface as a datum and program a tool library in your dro, further increasing reliability

You Americans are spoiled and detached. When Adam says "It costs 400 dollars, and its so expensive" it makes me laugh. In Poland (thats where Im from) this 3D tester costs PLN 1600 and a cashier in a supermarket makes PLN 2000/USD 500 take-home/month for 160h month. Realistically a cashier would have to spend full 3 months worth of savings to afford one (and thats under a proviso that they live alone in a rented room, never go out and really want this tester). And what about Middle East or Africa? These people would have to save up for years just to afford one. So no Adam, USD 400 in America is not expensive. It is laughably cheap- it is almost like it was for free. Just my "Rest of The World" perspective.

Zero milling experience but as soon as Adam held up the other edge finder next to the Haimer it clicked and I could tell exactly why this tool made him so excited and audibly “Oh!”’d. The 20 minutes of context was 100% worth it. As someone who doesn’t really “make” in the physical space I can still appreciate any tool or technique that reduces the time and opportunities for error needed for a process. Love it.

Is it your milling machine moving or your camera shaking?
PoignantPirate - 28 dager siden
Adam, I've noticed that you tend to bring the quill down when trying to reach things in your vice.
You should try to bring the knee and the vice up to the tool, not bring the tool down to the work.
The main reason for this is rigidity, but there's also a LOT of force acting on the quill, so using it at max extension will wear out the quill bearing surfaces over time and that slowly increases the risk of the quill moving on your during a cut.
The same thing somewhat holds true for the drill press when used as a spindle sander, it's always better to bring the table up so that the force on the quill has a shorter 'lever' to work with.

"...I am Imperial." Long live his Highness Adam!
Its actually US Customary Units just to drive us all nuts. But hey! We share a unique culture with Liberia and Myanmar; the only other countries still using units based on the length of Adams' feet. But I am a rebel and join with the other 96% of the world which uses metric on base 10 units.
Don't start into me that US Customary units are solely defined in terms of metric units. I tried that with my Dad. "Let's see: That's 18 feet 9 & 1/4 inches plus 22 feet 7 and 13/16 inches which converts into 5.721 meters + 6.904 meters equals12.625 meters converted back to 41 feet 5.047 inches." 39 years ago I got a slap upside the head for being a smart a**.
10 years ago I made a stupid memory error. Should have been 21/32. I wrote down 23/32. That was the final straw. I threw out, gave away and sold all but one US Customary unit 100' tape measure (for emergencies only plus carpenter squares), replaced all other tape measures, straight edges, indicators, micrometers, educated sticks and calipers with metric reading or metric capable. Never looked back. Never regretted it. Math is a joy. Estimating is much easier. Thankful every day and wished I had done it 40 years ago.

Today, there is no difference between using the english or metric systems when machining. Everything is done using base 10 in either case. The only difference is what the decimals represent. TLDR, using the metric system requires all the same mental math to be done.

@21:43 you demonstrate that the hammer edge finder is able show if your vice is parallel to your bit by pushing down the edge finder down onto the vice and going to the left side.

I have a CNC machine in my maker shop and quickly realized I needed one of these. Allowing me to set tool height based off of it then using it to locate parts in the machine made everything so much more enjoyable. The lack of setting a tool height on the bridgeport seems like it would limit it's usefulness. I haven't tried it on mine. Using it to tram in the vise would be helpful though I could surely see that.
I should have done a video on mine as like you my machines are all imperial units and my Haimer was metric. Unlike you I am unable to get metric tool holders for my machine. I ended up pulling the Haimer apart creating a fixture to hold the shaft and putting it in the lathe. Using a tenths indicator I very carefully turned it down to exactly either .7500 or .6250. That was a stressful day, that Haimer cost a significant chuck of the cost of the entire CNC machine.
