How to build CNC machine from granite and calibrate with 0,0001μm laser tool

[@aqgh1]

I've been watching this project closely ever since LTT reviewed one of your first samples. I now see why this was not so quick to get up and running. I did not know about this project early enough to be a backer on kickstarter. This video shows a lot of dedication to the art and I really want naked die cooling on a 9900K. Looking forward to getting my hands on your craftsmanship! Congrats to everything so far

[@NUDEcnc]

Alex! Thank you very much. Amongst everything that I have experienced, comments like yours are far more important to what I am doing. People like you are pushing me to change my perspective about humankind. I thought that the whole world is full of haters and jealous people. I cannot even describe how wrong I was

[@SuperYellowsubmarin]

FINALLY, a gantry with real sturdy squares between the Y carriage and the beam. I can't stand seeing so many machines compromised by the use of thin, flimsy plates where you used raised rails and a stiff angle aluminum block. Great design !

[@ChrisHarmon1]

Agreed. They look incredibly beefy. Would be interested to how it mounts as those look like some deep bore holes.

[@crazytrutas]

Great to see you back. Keep up the good work.

[@markclark4154]

Can the linear rails maintain 1pm accuracy? I would have thought that was linear air bearing territory.

[@stevenfuller3614]

Or hydrostatic oil bearings

[@Z-add]

Please show the laser calibration process in detail. You are now a dealer of that tech.

[@zdenkostanec1622]

Hello! Awesome machine, can you share what type of "anchor" are you pressing into the granite? Many thanks!

[@NUDEcnc]

Hi. You can look them up under Keep-nut anchor!

[@axelbostrom3606]

Well I am glad to see the machine doing the movements, now get a slab of copper under it and get going! 😄

[@NUDEcnc]

I'm doing my best. I have everything what I needed, so... NO MORE EXCUSES!!! ;)

[@aion2177]

what is the purpose of copper?

[@Z-add]

Where is the video where you used the laser measurement device

[@pfrillele]

Why are the sidewalls screwed on the side and do not stand on the bottomplate?Thanks.

[@mywalkingfriend]

hello again from san diego, california. so glad to see you have uploaded video .it has been such a long time but now understand why. your latest project is amazing ! looking forward in seeing more projects,gadgets and inventions from your channel.

[@NUDEcnc]

This is moment, when I'm for the first time able to develop new projects from start to finish by myself. THIS WILL CHANGE EVERYTHING :)

[@J1I9M7M4Y]

Amazing and beautiful machine!!!

[@TiMechOfficial]

hey REELLLY NICE MACHINE!!! i have seen youre software is UCCNC right? what is your cnc setup (breakoutboard, stepper driver, more...)?

[@ErtsenPlayGames]

czyżby inspiracja był projekt wykonany przez "Piotr Fox Wysocki" cnc z granitu , też Polak :D jeszcze trochę to Polska będzie przodować w cnc z granitu :D

[@JShel14]

why mount the gantry "arms" to the side of the table instead of directly on top?

[@gtxviper]

Cracking design.

[@scultzalex9781]

0,0001um it's a little bit exaggerated don't you think? You reached the scale of an electron or a proton...

[@lepidoptera9337]

Not quite, but it is the scale of a hydrogen atom, though. His cheap Chinese linear rails are probably off by at least 100um. ;-)

[@johnlacquey7240]

Merry Christmas Beast Master :)

[@TheMIroslaVbachev]

Wow first time I see a cnc that is accurate within 1/5 of the width of atom. That's crazy. My cnc is accurate only within the width of 5 atoms. Keep it up man

[@perspectivex]

Only the laser measurement is really precise. The cnc will be the sum of different errors; ball screw precision (wonder if he used ground C5/C3?), spindle runout, linear rail preloading and accuracy class, how the whole thing is supported by the table and if it's ever moved, thermal expansion, motor control errors, motion error correction, probably other stuff. The spindle looks like a JGL, www.jian-ken.com/automatic-pneumatic-tool-change-spindle-motor/jgl-100-2-5kw-24000rpm-iso25-spindle-motor.html which is stated there to have 2 microns runout. Add everything else on top of that. I guess this machine might be accurate to 10-15 microns? Just a guess. That's still quite good but something like a factor of 10^5 more than you're thinking. I guess you were kind of joking in your comment but I think a lot of people might not realize it's super hard to get micron precision. An example of a sub-nanometer accurate machine is shown here kzbin.info/www/bejne/q4bPppaVnNeDgqs.

[@TheMIroslaVbachev]

@@perspectivex I think you misspelled sub-nanometer. For reference one atom is about 0.5 nanometer in diameter. Such presision I would say it's impossible to achieve even by lapping. Even micron precision is difficult to achieve just by machining, and that's 1000 nanometers.

[@perspectivex]

@@TheMIroslaVbachev i think you might have read my comment before I corrected that typo...I saw it the split second after clicking save, sorry. Anyway, I get that it's nearly impossible to operate "large" equipment at nm scales but if you look at the link to the video segment it shows that ASML machine which operates with sub-nanometer precision. True, not really a milling machine as it's doing photolithography but apparently it positions things to sub-nm, which is still pretty amazing (I know there are also piezo linear stages that do sub-nm movement; www.pi-usa.us/en/tech-blog/sub-nanometer-resolution-piezo-linear-motor-with-interferometer-feedback-pi). I agree lapping typically only gets you to a dozen or two nm at best (quality optical flats are a good example of a highly lapped&polished surface in that range en.wikipedia.org/wiki/Optical_flat) but you can "machine" a surface to ~3nm with electrorheological polishing www.researchgate.net/publication/229121322_Development_of_a_padless_ultraprecision_polishing_method_using_electrorheological_fluid. But I guess there dozens and dozens of other problems to contend with if you really wanted a sub-micron to nm milling machine with a decent build volume (you could position atoms with an atomic force microscope but that doesn't really seem like milling to me).

[@scottwillis5434]

Don't confuse measurement resolution with positioning accuracy or resolution.

[@MF175mp]

I bet the resolution of that measuring tool drives you crazy. What kind of tolerance specs did you aim for and how tight tolerances can it now keep on a part?

[@kallestrom4009]

Are you selling these chassies?

[@ShopperPlug]

Does the axis rails use air bearings? How long did it take to build it? What is the repeatable accuracy?

[@TheChrisey]

Air bearings... lol those are just regular ball bearing linear rails

[@crappymachines7567]

Hi. First of all, great build. I got a question. In minute 1 we can see you hamering in threaded inserts into the granit. are those bought of the shelf, or are they selfmade? If so where did you get tehm or how did you make them?

[@hempathy]

I'd like to know this too!

[@spankeyfish]

he replied to another comment that they're Keep-nut anchors

[@brahimiamar4471]

I cannot see much of a build ? Is there another video really showing the build ?

[@decornails1355]

I really want to refer to the drawing, can you share it?

[@Javi-ds9bj]

Saludos desde España! Brutal proyecto. Me ha encantado. ¿Donde has conseguido los insertos roscados para el granito? ¿Con que nombre los puedo buscar? ¿es granito de las mesas de encimera, tipo mármol? saludos y gracias

[@3dkiwi920]

This looks alot like Piotr Fox's Machine!

[@NUDEcnc]

You are totally correct! I did contact Piotr during designing phase! He is a great guy and was very helpful. I have spindle from the same company that he has. I can only confirm it is as impressive as he described in his latest video kzbin.info/www/bejne/nmrUZ51thbSahas

[@HitTube]

ciekawe czy do 2025r zaczniesz produkcje tych waterblokow

[@NUDEcnc]

Produkcję to ja już dawno zacząłem, pytanie jest kiedy ja ją skonczę ;)

[@jimlahey5354]

No Linux cnc??

[@okiiPL]

Wygląda super

[@jordon4473]

Awesome build! Odd sales pitch though.

[@NUDEcnc]

To be honest I couldn't decide if to brag about my "awesome" design or someone's surprisingly capable laser tool...still learning

[@satchelsieniewicz5824]

Very interested in a build videos !

[@avfbvdfbv]

wher you working ? ,, city .. if i want to visite your company

[@shumailriaz9204]

Great, always wanted to build epoxy granite, but i guess granite alone is also good enough

[@CNCPRINTBLOGSPOT]

Very nice Job! Looks Like mine cnc too, but mine is made out of concrete. UHPC. I would Like to see the calibraton. Top! 👌👌👌👌

[@NUDEcnc]

Next time I would probably build hybrid concrete-granite setup. As for calibration I want to make few videos about this calibration tools , as they are really capable.

[@GreekPcFreak]

i admire this project.. but is it actually 1nm capable? this could even be better than samsungs 7nm EUV process :P of course i have no clue about wafer cutting and just metal cutting, how far is silicon crystal from this?

[@scottwillis5434]

I'd want to be clear on measurement accuracy vs. measurement precision vs. positioning accuracy.

[@user-rb2yb9rx1c]

Nice! I create a machine from polymer concrete, 1000x1000 mm, high precision, I would not be in the way of such a measuring tool. How did you get it?

[@NUDEcnc]

Hi. if you are still interested in the measuring tool can you please drop me an email at [e-mail] and I will send you all the necessary details!

[@BrotherCreamy]

Why natural granite instead of epoxy granite casting? Don't think I've ever seen another mill made of natural granite.

[@scottwillis5434]

See Piotr Fox Wysocki, m.kzbin.info/www/bejne/nYaplqJ6m5aMrK8 Epoxy granite has its points, however it apparently is subject to slight absorption of moisture and possibly degradation of the Epoxy (chemical, UV, thermal). Then you have to create a mold, do the casting, get the cast part out of the mold without damaging it, etc. An inexpensive granite surface plate costs (US) a few hundred dollars (depending mostly on shipping) and comes flat within a few tenths of a thousandth of an inch.

[@house89147]

I am in the process of building a couple of CNC machines my self. I would love to know what parts and suppliers you got bits from like the spindle etc and what controllers your using. I realize you have a business to run and I still would like my ncore but as both an IT professional and a hobby machinist I'm interested is more than just the end product in this case. Also I think it would be good to get a demo/info on how it was calibrated and if we can pay to get this done for us it would be very interesting too.

[@NUDEcnc]

Hi Andrew! In regards to the parts, there were so many of the suppliers! can you drop me an email at [e-mail] We are currently working on the video with an instruction manual of laser/ calibration, should be up soon...

[@Javi-ds9bj]

Nema34?

[@nickab9719]

Something wrong with your website?

[@NUDEcnc]

Yes it is... unfortunately ...I am trying to deal with the problem. If you are interested in Ncore or Nlap you can go to nudecncshop.com if you are interested in metrology tools drop my and email at [e-mail] and I will Forward all necessary materials :)

[@crazytrutas]

What control software are you running?

[@johnlacquey7240]

I'm beginning to consider the investment just the price of admission to having been able to watch one of the most inspiring person I've seen do his magic.

[@NUDEcnc]

Thank You.

[@GordonGEICO]

I don't think the words "How to build" mean what you think they mean.

[@fabianmartinez39]

But that sistem has to be something out of rech of the diy person

[@fabianmartinez39]

How much can something like that cost

[@JorgeMarioManuelOrtega]

now build a nutating head

[@scottwillis5434]

It's a promotional video. Don't call it "how to".

[@korneliuszjakobik1594]

Przeost formy nad treścią i wydanie pieniędzy niepotrzebnie :) można by się tak rozpisywać ale pamiętajmy maszyna jest tak dokładna jak jej najmniej dokładny element :) Np. stół granitowy zeby maszyna była odporna na zmiany temperatury... co z tego jak nie zastosowałeś liniałów pomiarowych a sruba pracuje :) juz dokładność leci na łeb na szyję...

[@NUDEcnc]

Oczywiście, że precyzja urządzenia jest absurdalna do potrzeb przemysłu CNC. Jednak cena urządzenia i możliwości ustawienia zarówno pełnej geometrii dowolnej maszyny CNC, pełnej diagnostyki ruchu dynamicznego, (częstotliwość próbkowania 900tyś/sekundę) oraz potencjalne dodatkowe zastosowania, czyni je bezkonkurencyjną ofertą rynkową.

[@whitegod8755]

So essentially what your saying is youve been slacking off and you have nothing to show for it, how typical for your flake generation.......

[@alexmay3533]

You mean 0.1 micron
