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.
That hose clamp putting in work 💪
Owner of my shop lost his front teeth using a hose clamp. Part spun and shoot off the centers.
I love this channel! You guys are absolutely perfect! Thanks for sharing your talents
Crazy Chair, BOOM!
Haha its built for comfort!
Thank you for the video. I would love to see gears being ground on the S31. Keep up the good work!
Awesome work. Love your programing station (fancy chair with screens). Boom!
Nice work as always. We shared this video on our homemade tools forum this week 😎
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
Once again i find another ToCNC at ten minutes old. 5 videos in a row now
i think it might be my super power
Oh, Man! Griding machines shines!
THAT was freaking cool!
Badass, period. 💥
More grinding videos please and please do something like grinding hardened steel
Very cool 😊
Vocês americanos estão realmente em outro nível... Um abraço aqui do Brasil.
Very good 👍
Nice work!
Is there no tolerance on the thread pitch?
Next time you need to grind on a knurled handle.
Higbee thread 🤩🤩 would be nice to see the process!!
Nice job man.
Thanks for watching!
Beauty!
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
I always wondered what Chris Hadfield did after retirement.
In 1998 for my final machining test in highschool I had to make acme Jack.....
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 TH-cam 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
Sweet!
Guys, forget CNC for a moment and get a conventional lathe for roughing operations. It will help you save a lot of "MONEYYYY".
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
Great content guys
Could you share what coolant and coolant levels you are using in the studer
We are using Blasogrind S35 at a 3% concentration level. Thanks for watching!!
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.
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)
Epic
Have you ever made go/nogo thread gauges out of Invar36?
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.
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
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.
@@christobel Pretty much answered that question for me!!
@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.
A vid on measuring threads?
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.
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.
Your work place probably had problems with people making mistakes reading the scales.
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
Does anyone know what kind of strel a regular go/no go gauge is made of?
is it okay if people who like cnc machines want to visit their place?
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
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
Yes boss this chair is going to make me a better programmer, What do you mean?!
@titan could u show me the laser parameters?
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?
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 .
@@legggl8648Okay, thanks for the explanation
The center is spring loaded
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
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.
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.
Now that's impressive Butt where is Barry
Im watching the video from michigan 😂
@@barrysetzer guess what I went Michigan A year before on this day
I want to see more AK 50 parts
On the hose clamp drive dog:
How did you affix the pin to the hose clamp?
It is custom made and brazed on!
@Christopher Villalpando
I zoomed the view and see the braze now. That is a clever way to use a hose clamp as a drive dog!
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.
That is a proper method, however, you need to also check with the ring gauges or make one on the next video! :D
How to make a blunt start in all threads in mastercam
Excellent video. My only concern is that profile needs to be dressed with compensation because no titl angle on the wheel
Program makes the compensation
What is that chair? I want one.
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.
Where did you get that part driver from?
😂😂
😎🤙🦅
Все здорово, станки огонь, но какой смысл целиком на шлифовке делать? не пойму. Не проще сделать заготовку на токарке с припуском??
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
@@Vasu1982ca эти согласен, я про заотовительную операцию, её на токарном с припуском 0.8 на диаметр. Думаю за глаза хватит
@@urunir5636 хороший вопрос, предположу, что там грубый камень был, которым не жалко было выполнить не рабочую поверхность, либо токарный был занят
my cutom made go/nogo gauge are made on my lathe lol
Thank you for not doing the American Super Hero CNC Hollywood style video
Your forgot to video or mention the Higbee
Why wasn't all that meat removed on a lathe?
Go no go gauge ready… and it is for sale for just $5000, or for 10 easy installments of $600 each it can be yours 😂
dude does not need that insane emporer gaming simulator thing to use programs lmfao
whew my aim on cnc is .5 mm this is sho nuff tite tolerance
I'm early
loudness is all over the place, the editors should know how to match loudness across the clips
For what the 7000$ gaming chair tho lmao
Who ordered that $10k monstrosity of a workstation? Looks uncomfortable 😅
Як на мене це не правильно ! Я би заготовку перед шліфовкою проточив на токарному! Я більш впевнений що камінь в рази дорожчий чим пластини !
Hellow good morning
I serch work of cnc
Yeah this guy also made the parts to raptor engines also fail army
Roughing on a grinder. Sounds strange to the ears of a manual machinist.
Oh yea normally grinding is removing .01-.015 off a finished part. But we can still creep feed grind such as Jessies 1in depth of cut!!
“Dark to shiney?” Hate it when suits hover :)
“Fuck off I’ll call you when it’s done”
why do say "automotive" and "medical" like its really hard core xD
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.
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.
