I literally did exactly this yesterday. 1.500x8 Stub Acme. I usually make my gages a little over the minimum pitch diameter and a little under the maximum to ensure a “real” gage will run okay. It tightens up the tolerance I have to play with when running the part, but it’s worth the peace of mind.
Had a job where they wanted 200pcs of .030 steel laser cut and tapped in 2 places each with a 0-40 thread, turns out that by the time the no go bound in the part, it formed the thread enough to make a second pass with the no go, out of spec. had to have the inspection head come watch me do a piece with a brand new tap and check it himself, the customer ended up pulling the job because they wanted 100% inspection on our end and then they were gonna repeat the inspection before they accepted the part
Wow Titan Gilroy that studer grinding what the chair and all the computer screens is f****** amazing!! I mean I did see the first day when you got that machine on CZcams I know I got to sign up for the Titan academy of CNC i keep putting it off You got to show us more on how the chair works and the computer screens up on top and why there are three or two and everything else and do you still have all the other studer grinding machine you purchase wasn't one of them over $1000000 something like that and how come that one was so much money I mean they're all very very expensive just very curious i always want to know why and how things work since the day I've been born lol I can just imagine how expensive those studer grinding machine spindle I mean something tells me that they got to be very well engineered wet extremely high tolerances I don't think they're your ordinary angular contact match set of spindle bearings I would probably think that's studer has them either custom made for them or studer is making the spindle bearings themselves in-house I wonder if they use like a high-pressure oil pump on The spindle bearings what a very good micron filtration system
We make UN gages all the time. Unfortunately you can't make an ACME or STACME thread gage with a regular acme/stacme thread insert. But dressing a grinding wheel works just fine 👌
@@ImStevee the minor, pitch and root width dimensions of the gage dont align with the form insert. You have to have a smaller minor than whats possible while still hitting the pitch
Weird question but how do you guys create perfect center holes on both sides? We get variations of ,005mm on diameter when we measure around the part with 2point measure
My shop turns every part between centers after we drill them. Throw a center in the chuck, zero and line it up with the tail stock then make a few skim passes on it.
Is there a reason why you roughed the OD on the grinder instead of getting it turned on a lathe first before heat treatment? Seems like turning and leaving heat treatment/grinding allowance would be faster than roughing down what looks like 20mm per side with a grinding wheel (I'm an apprentice so this is a genuine question for the sake of learning)
Items can be calibrated in house if they have the capability, but I like to send my own gages to an A2LA ISO/IEC 17025 accredited calibration laboratory with all certifications traceable to SI units through NIST.
If a contract comes in with a thread for that the shop doesn’t have a gauge laying around you simply buy one and when the parts get manufactured you are ready to go. Simple work preparation.
Chris, that was a really neat op. I am curious as to the differences with using a grinding wheel to create something compared to using the lathe to make the part?
This part, with its tolerances and condition, could have been completed on a lathe without issue. In gauge applications, the material would have been hardened, and would pose a challenge machining on a lathe. Grinding would be the way to go then.
@Chris Morris thanks, that makes sense then to me now. I do find it interesting how with a grinding wheel your able to get such tight tolerances. Gotta love machines and computers for this.
I've always understood that grinding gets a bit better surface and tighter tolerances Vs hard turning, at the cost of time and having to look after the wheel. However when there is a interrupted cut you probably have to grind as the hard turning inserts tend to be too brittle.
I wonder if it was necessary to flip the part twice. Could you have done the major and the thread at the same time? Or is there a reason you made it this way?
everything is wrong there to make caliber this way, but??... , some special thread is it one piece, is it working ? probably yes, did they demonstrate the machine well ? who cares. Anyway i love Donnie and his swiss turn lathe style. Others of guys are just boring... Boom is just gone .
Well there was a change of the grinding wheel in between, and I don't know much about grinding especially on such a level of precision and complexity, but either change of wheel introduces more potential for error and required work to mitigate it rather than flipping the part Or it's simply quicker to do one wheel change (regular to thread), rather than three (regular to thread back to regular and yet again to thread), all assuming that the last one is left on the machine all the way up to next tasks on a different job which could require yet another wheel altogether. Otherwise it's "one and a half" change (one change and taking the wheel off to leave an empty spindle) or 'three and a half' Either way, former is quicker than the latter, and I suspect that error mitigation after flipping the part (it was just a moment ago ground on this exact setup, assuming Titans live up to the image they created on YT, they keep their machines in good enough condition and regular servicing that setup is all within square, concetricity, in turn being symmetric on the 'imaginary', 'non-machine' axis on which part was flipped end for end etc) is a risk worth taking to save time - as in, time, it potentially will take, to get within true axis at a bad case scenario is short enough to still be a save (or more preferable time spent effort-wise) compared to few more wheel changes
Can you suggest how to drill 1,2,3mm holes using HSS drill to the depth of 40mm in a VMC? I tried mine, but at the bottom, the hole went out of its axis.
I think it would be difficult to do this with HSS. Its bending too much at this size. I think your best bet is Carbide, cuz HSS is always gonna wander away.
Just a question at the beginning of the video. Is it correct that the tailstock center don't have to rotate as well? 1:05 I thought that the friction between the part and the tailstock center will wear the both of them down and it will start to loosen up?
I have an interesting question. I noticed that you use an analog micrometer instead of a digital one. Is there a special reason for using that over a digital? My workplace has “banned” analog and only uses digital now, so it was kind of surprising to see that you still use these wonderful measuring tools.
There isn't. Chris prefers to use a standard at the machine; I use digitals in inspection. If you know how to use and read it an analog micrometer will work for most cases.
I have found that digital micrometers are susceptible to shock loading so if you approach the part too quickly you’ll get some error due to the difference of a design from analog. Surprised they banned them but probably depends on what tolerance you are working in
I don't understand how a go-nogo gauge could check the tolerances on more than a single parameter: a single parameter in spec would be enough to prevent the nogo side to work, so how do you verify that are ALL in spec? Shouldn't you do two "go" gauges with the upper and lower sizes?
Exactly so, at the lead in only. A machine shop owner I used to visit as source inspector showed me how to use a punch to deform lead thread and prevent "no-Go" gage from threading in. A reprehensible act that illustrates your question. As the name illustrates, hard gaging is only a quick accept/reject tool; does not supersede measurement.
Червяки редко, но тоже с нуля из круга вышлифовывают. Такого качества поверхности не добиться на токарном. К тому же в каждом проходе срезается сотка, или десятка припуска на резьбовой поверхности, сотки в резьбы ловить на токарном сложно, скорее всего так
I don't understand why you wouldn't rough most of that material off with a regular lathe first. Roughing that much material with a grinder can't be cheap.

Nice work as always. We shared this video on our homemade tools forum this week 😎
Epic
In 1998 for my final machining test in highschool I had to make acme Jack.....
THAT was freaking cool!
out of curiosity, how long did this grinding take ???for the entire Guage
My question too! For sure faster than having a gauge company make one.
I always wondered what Chris Hadfield did after retirement.
We make UN gages all the time. Unfortunately you can't make an ACME or STACME thread gage with a regular acme/stacme thread insert. But dressing a grinding wheel works just fine 👌
Why is that? The full form insert isn’t designed for the go and no-go dimensions?
@@ImStevee the minor, pitch and root width dimensions of the gage dont align with the form insert. You have to have a smaller minor than whats possible while still hitting the pitch
What is the motivation for not roughing this part on a lathe? It seems pretty overkill to me to make in entirely on the grinder
Flex so they can say we did it all on the grinding machine
Yes boss this chair is going to make me a better programmer, What do you mean?!
Nice!!! Verry Nice Machine!! But how did you grind the start/end of the tread? Is it also grind on the Studer S31?
the threading cycle has a built in lead in/lead out angle
Nice job man.
Thanks for watching!
Does anyone know what kind of strel a regular go/no go gauge is made of?
Higbee thread 🤩🤩 would be nice to see the process!!
As long as you have the dimensions it's not that difficult.
Even if ya dont it's doable if you know how a go and no go works.
Weird question but how do you guys create perfect center holes on both sides? We get variations of ,005mm on diameter when we measure around the part with 2point measure
Normally you would use a center grinder to align the center holes

Damn I didn’t know PJ from Grandma’s Boy was into machining
Nice work!
Is there no tolerance on the thread pitch?
Next time you need to grind on a knurled handle.
If used for aerospace parts, doesn't it need to be sent out for certification?
At my company all gages and measuring tools needs to undergo calibration/inspection once a year and we don’t even make parts for aero.
Items can be calibrated in house if they have the capability, but I like to send my own gages to an A2LA ISO/IEC 17025 accredited calibration laboratory with all certifications traceable to SI units through NIST.

The centers are made from cabide, they are super hard and therefore basically dont wear at all.
Also on the tailstock there is a cutout on the center, so u can grind closer to the center, you can see this cutout at 6:15 .

The center is spring loaded

How did you affix the pin to the hose clamp?

A vid on measuring threads?
How to make a blunt start in all threads in mastercam
Great video; but why flip the part between ops instead of going NOGO major & NOGO thread with perfect concentricity, then GO major & GO thread?
Why bother getting perfect concentricity between the two when this is easier?
why would concentricity matter in this use case. Sounds like a waste of time
He is turning between centers so concentricity is presserved
Why wasn't all that meat removed on a lathe?
That is a proper method, however, you need to also check with the ring gauges or make one on the next video! :D

Roughing on a grinder. Sounds strange to the ears of a manual machinist.

I don't understand why you wouldn't rough most of that material off with a regular lathe first. Roughing that much material with a grinder can't be cheap.
Wouldn't that gauge need some sort of surface treatment?
This gauge isn't going to see much use as explained at the end of the video.
