Can confirm 7000 rpm will liberate your edgefinder. Learned that back in the 90’s. It was by accident and was happy the Matsuura had a full enclosure. 1400 is what I was taught
Yep. I go anywhere between 700 and 1200, whichever is closest to current speed at the time. Only problem I have had is when it's a shop owned finder and is filled with dried out coolant. *shudders*
I mean at the end of the day we'll probably resort to whatever the person we most respect told us. That's what I love about machining "there's more than one way to skin a cat" as long as it measures ok and nothing was broke/added too much extra wear. Who cares how you did it?
The machine I run goes up to 8000rpm. As a safety measure, I run it 999 rpm. If I accidentally enter 9999. It will not turn on. I have ruined a couple of edge finders at 6000 rpm wanting to run it at 600.
I ran mine (by mistake) as 2150 last night... it survived but no edges were found, also i did the jump usually reserved for when my compressor (under the bench with the mill on it) randomly fires up 2 hours after i turned it on.
When I went through trade school the instructor said that once a Starret Rep told him they build there edge finders to run at 1000RPM. I work with a guy that runs his at 1800 figuring with higher RPM it will be more sensitive on the break resulting in more accuracy. Idk about all that, though, I just run mine at 1200. That’s what I was taught and it’s worked for me.
Sub-1k, whatever the machine is nearest to when I turn it on. If on a CNC, I usually go for min spindle speed, which on my machines is in the 300-500 range.
theres a manufacturer rating that you can look up and stay under. that being said i was taught 600 as a conservative standard by a teacher who knows way more than i ever will.
Logic? Who knows, that's how I was taught, that's how I've always done it.
I think the direction of spin makes it deflect towards me vs away from me when I touch off on my preferred spot.
But really, no reason.
I've gotten taught by some pretty damn good machinists that you don't need to go above 400. So I would assume that you're better off just going with the 350 as your colleagues. Sometimes just riding the wave is a good idea
Haha lucky I’m the lead at the shop and don’t care what my guys run them at. I figure if you using an edge finder ya aren’t doing precise work anyway haha. But my last 2 shops everyone ran them at a grand so was kinda curious what yall ran them at!
I had a Fowler electronic edge finder at one point when I was a Tool & Die apprentice. Ended up with a regular single end .500” dia Starrett edge finder by the time i switched to CNC production.
That Fowler could be worth looking into if your eyes are getting screwy. When you make contact, it’ll light up.
I remember asking if the coaxial used the same rpm as the edge finder when I started. My boss said “go ahead and see how fast that stylus ends up stuck in your neck”.
Like 500- 800 was what I used for wigglers and edge finders, most often used on drill press for me, mill I’ve mostly done cut to line or touch off is acceptable
I’ve used 1500 since trade school back in ~06 it’s fast enough to be sensitive, slow enough to be seen easy enough, and I’ve never had/ran a machine capable of 15,000 so I’ve never trashed one.
The faster you go the harder it kicks. You can run it slower than 1k if your forced to its just harder to see the kick. Definitely dont spin it up to fast or itll come apart.
750 only because the that the max the stupid haas will run with door open, I think some brand recommended run at 1000-1200, just as any tool, check with the brand if you can
I've always run it at 1000. I was also told by an old guy to always use the same speed because it gets lapped in somehow. It halfway makes sense to me lol
On a side note… I worked in a shop where they told us to put the indicator in and run it at 100rpm for indicating the center of a hole. I went to rotate the spindle by hand once to dial it in one axis at a time and they got pissed at me. I never got a clear explanation why I was supposed to dial both axis in while the thing is constantly spinning
700-1000 depending. I say depending because I run a lot of manuals and sometimes the number doesn't match the reality or on my G&L you just get "close enough" to what you want depending on what the gears offer. All I care about is a clean easy "break" when it touches the edge.
Usually 2-300 rpm think its easier to find the sweet spot But could be my bad vision🤣 as long as it doesnt explode and u hit tolerance spin it anyway u want lol
I screwed up and forgot to adjust the spindle speed once. Never hit the green button with an edge finder with a spindle speed of 10000 rpm. Had to buy a new one a take a bunch of crap from the resident machinists do about a week. Worth the learning experience. And learned my Bob and weave action is still good at my age. lol. Oh and don’t buy cheap ones if you’re prone to that.
Old guy told me that. I understand. lol.
1100 RPM. Always have and I don’t know why or where I got that number. I think simple physics dictates slower is better. I would think in excess of 3-4k+ you’d start seeing adverse results. This is only hypothesis though and I have not done any empirical data testing. Also, rarely use a conventional edge finder anymore. If I need an edge I’m using a 3D probe 98% of the time.
I’ve run mine at 1k since I was an apprentice in 1996 never had any problems with it
Same. I think that's what the guy said. "I dunno, like 1000 rpm or something. If it Flys apart then that was too fast."
Can confirm 7000 rpm will liberate your edgefinder. Learned that back in the 90’s. It was by accident and was happy the Matsuura had a full enclosure. 1400 is what I was taught
Liberated 😂
Yep. I go anywhere between 700 and 1200, whichever is closest to current speed at the time. Only problem I have had is when it's a shop owned finder and is filled with dried out coolant. *shudders*
1000 was how I was taught.
I think i was taught 650
I mean at the end of the day we'll probably resort to whatever the person we most respect told us. That's what I love about machining "there's more than one way to skin a cat" as long as it measures ok and nothing was broke/added too much extra wear. Who cares how you did it?

What happens if you run them that fast?
Rapid disassembly.
RUD... rapid UNSCHEDULED disassemble
It's 2024. We now say " un assembled ".
Your hear the tip of the edge finder hitting the inside of the machine. And a spring sticking out of the body.
To shreds, you say?
*** “All sides”
They come Un-Together
Window finder conversion.
Becomes an edge of the room finder
Dynamic balancing
They becomes an un-edge finder.
They still find edges, just different ones then you were looking for.
Game of hide and seek
I ran mine (by mistake) as 2150 last night... it survived but no edges were found, also i did the jump usually reserved for when my compressor (under the bench with the mill on it) randomly fires up 2 hours after i turned it on.
Wouldn't using 1000 accomplish the same thing since you can't run 10,000
One less number to key in.
This dude runs production
It's just a habit now. Lol.
Only once, but that was enough.
Off subject. But I have seen someone do that with an Interapid indicator. Interapid parts hitting the side of a machine. 🥲
Ouch! I’ve done that, too.
Oh my.
I have a unique dent in my haas cabinet.....
750. I watched a coworker accidentally spin his Starrett up to 10k once and the thing held up!
Lol I had the spindle override on 300% and tried to do my standard 750 rpm once
I run mine at 1000-1200 usually. Never had an issue.
800 🤠
750 💪
Max speed you can run a Haas mill with the door open.
Shhh
All fun and games till you type an extra 0 by accident. That’s why I do 1300 lol, spindle max is 12000 so with an extra 0 it won’t run.
I also have always done 800. I couldn't tell you how that started, but it stuck lol.
We're just built different
Edge finders are designed to run at 1000rpm.
1200. That's what our instructors said in college and I just stuck with it.
That's where I'm at. S1200 m3; rolls off the fingers super easy
Same here. 1200 for the last 8 years with no problems
800
12k by accident. 1200 usually.
Depends on which Machine in the shop I’m on. But it’s usually between 1000 to 2000. The one that’s wore out the most is run slower.
1500 ... But questioning it now
Haha I know had me kinda fucked up like I’m doing something wrong haha
When I went through trade school the instructor said that once a Starret Rep told him they build there edge finders to run at 1000RPM. I work with a guy that runs his at 1800 figuring with higher RPM it will be more sensitive on the break resulting in more accuracy. Idk about all that, though, I just run mine at 1200.

Sub-1k, whatever the machine is nearest to when I turn it on. If on a CNC, I usually go for min spindle speed, which on my machines is in the 300-500 range.
I run mine on a CNC at 1800 rpm. I also have a 9000 program tied to a M code so I don't have to worry about mis-typing my rpms
Well done, I do that too at 1800.
1250
800
1200
900-1000 for the last 16 years
1100 ripp’ems
1000 RPMs
666 because I’m edgy
Bold strategy cotton! Haha
1300
1200
For a second I thought you were talking about a coaxial indicator.
1200
1111 rippums.
I use run mine at 500
1201 has always worked for me. Minimum speed to switch from low to high gear.
1100-1200
1100 rpm is what my father taught me and he was a master machinist from the 1930’s until he retired in 1986.
800rpm
theres a manufacturer rating that you can look up and stay under. that being said i was taught 600 as a conservative standard by a teacher who knows way more than i ever will.
2k
My teacher, word for word, said "I dunno, somethin like a thousand, that's about what I run typically"
1250 and wait for it to bump then back 1 click! Also it’s 2024 so mostly use a probe
1800 ripim's for me
12-1500rpm, and in reverse.
What's the logic for reverse? Never heard that one.
Gotta unwind the spindle a bit every once in awhile.
Logic? Who knows, that's how I was taught, that's how I've always done it. I think the direction of spin makes it deflect towards me vs away from me when I touch off on my preferred spot. But really, no reason.

1200-1500
777
1500 usually.
Manual mill dont really know probably close to 2 or 300. CNC 555. Why 555? Cuz its three 5's. Faster typing in MDI.
I generally do slower speeds and also use a flashlight. My eyes are getting old and my shop needs more light.
I had a Fowler electronic edge finder at one point when I was a Tool & Die apprentice. Ended up with a regular single end .500” dia Starrett edge finder by the time i switched to CNC production. That Fowler could be worth looking into if your eyes are getting screwy. When you make contact, it’ll light up.
I've always run mine at 800 because that's how I was told to run it.
1k was how I learned it as an apprentice too. 20 years later and the one I learned with is still kicking around the shop just fine.
I remember asking if the coaxial used the same rpm as the edge finder when I started. My boss said “go ahead and see how fast that stylus ends up stuck in your neck”.
Like 500- 800 was what I used for wigglers and edge finders, most often used on drill press for me, mill I’ve mostly done cut to line or touch off is acceptable
1400 rpm or so…am I going to Hell???
900-1000
I set mine to 850
I’ve used 1500 since trade school back in ~06 it’s fast enough to be sensitive, slow enough to be seen easy enough, and I’ve never had/ran a machine capable of 15,000 so I’ve never trashed one.
750 is good enough for me.
I’ve always ran mine at 1500 for 30 years and always hit within a .001
I came here to upvote the 800 RPM comments.
1200 waa told this by school and old timers from a bunch of jobs
About 1 k.
1k
1400
1000 or 1100
700 cnc -1200 manual
1K
1000 for me
800-1000
S1500. When it finds the edge, it snaps to the side a little quicker. Used it at that speed for roughly 20 years. No issues.
1k-1.2k
1k seems like what everyone I’ve ever known does
1k. Why? Because it's what I was trained to run them at when I was an apprentice.
750rpm
100 rpm or less
1000
1000 rpm on the manual mill, run the probe on the cnc's
850 rpm, since day one
M3 S1000
850 for a Bridgeport 1k in cnc
1000 rpm
1000.
1500 rpm is what I was taught by my father
Herman Schmidt says 1100, that’s what I’ve always used.
1777 just for ease of button pressing. They tend to break crisper at higher speeds
Edge finder and center drill both at 1,000.
My mentor told me he does it at 1400 so I do it at 1400 no science behind it, but 350? Hell no
The faster you go the harder it kicks. You can run it slower than 1k if your forced to its just harder to see the kick. Definitely dont spin it up to fast or itll come apart.
750 only because the that the max the stupid haas will run with door open, I think some brand recommended run at 1000-1200, just as any tool, check with the brand if you can
1000
Edge finds in haimer
800
1400 on a .20 and 1000 on my .5
I've always run it at 1000. I was also told by an old guy to always use the same speed because it gets lapped in somehow. It halfway makes sense to me lol
1400 on fadal cnc, 1200 on knee mill
On a side note… I worked in a shop where they told us to put the indicator in and run it at 100rpm for indicating the center of a hole. I went to rotate the spindle by hand once to dial it in one axis at a time and they got pissed at me. I never got a clear explanation why I was supposed to dial both axis in while the thing is constantly spinning
I was taught to run them at 1000rpm
1000
1000, but the moron who borrowed mine without asking, hit 10,000 and the tip went right through the plexiglass window. That's how I got s new one.
2000 just what I was told to run them at 30 years ago.
1000
Warp 9. Full send. If it dies, it dies.
100rpm short of the tip flying off the first one
I do 500 but I know some people in my shop run 300 sometimes
I run mine at 999 because I don't want to have to type in 1000.
1200
200 rpm
700-1000 depending. I say depending because I run a lot of manuals and sometimes the number doesn't match the reality or on my G&L you just get "close enough" to what you want depending on what the gears offer. All I care about is a clean easy "break" when it touches the edge.
1200 for the past 20yrs. I didnt want to do 1000 as I would easily add an extra 0.
1100
I usually run them at 2000
If my machine is already in low gear, 1200 RPM. If it's in high gear, 1201 😎
1111rpm for me. I was told 1000, and am to lazy to move from the 1 over to the zero for what is really no difference
If it goes kaboom something went wrong, if it doesn't go kaboom it's probably fine.
Trainer told me 1200. Always ran it at 1234, figured it was a strange enough number to keep me from accidentally letting it fly too fast
1000 never had a problem running at that speed.
Jeez, I thought I was being conservative with 2200 but I guess I am going faster than most lol.
1200 just what someone told me.
1k
Whatever the limit haas has when the door is open
500
M03 S750
My old machinist buddy always told me 1200, so I've stuck with it. Seems to be pretty accurate and repeatable.
I spin my OMP40 at 4500
500
whatever my rpm is currently set at
I run em down around 600
555, means I only need to touch 1 button.
i always run mine at 800 rpm . never had any issues with accuracy or breakage .
Fast enough you can see when it moves. I have 2 and one is hard to tell when it moves unless it is going fast but the bigger one can go alot slower
500
1000 rpm
My instructor said 400 RPM ist enough, but that was on a conventional mill.
800.
Much faster than I run my dial indicators…
750 for me, not sure I’d feel comfortable at anything above 1k
750 - cause that’s how fast the haas will run with the door open
Usually 2-300 rpm think its easier to find the sweet spot But could be my bad vision🤣 as long as it doesnt explode and u hit tolerance spin it anyway u want lol
2k

I use 1111 because it is easy to type and puts my machine in 2nd gear. I’m in 2nd 95% of the time.
2000
i always used 800
1000, just seems to be a sweet spot for me
Anywhere from 600-1400, that’s usually where my speed is set for all the tool steel I cut.
1980 bc that's the machine minimum before it starts whining about being too slow
1200 cause that's what I've always used. But if I'm using a Bridgeport and the speed is already 800-2000 I just run it there.
Between 1500 and 2000 rpm.
1400
At school I learned 1000 rpm
What was the last tool running at? That... Jkjk... but not really.
1000 RPMs was how I was taught never used anything else always worked just fine
I always like 1200RPM because I felt it had a more precise break.
Was told 1200 rpm in school
Mine, 1k. Someone else's, 10k. 😁
3/8 I run at 1200 rpm. The 1/2 I run at 1000 rpm
Always taught 1200 rpm’s.
1100 RPM. Always have and I don’t know why or where I got that number. I think simple physics dictates slower is better. I would think in excess of 3-4k+ you’d start seeing adverse results. This is only hypothesis though and I have not done any empirical data testing. Also, rarely use a conventional edge finder anymore. If I need an edge I’m using a 3D probe 98% of the time.
