Making a DIY CNC Metal Lathe | The Lathe Chuck + First Tests | #6

[@mr.ranyhomemade2466]

So cool your homemade

[@GBWM_CNC]

Thank you! 😁

[@mr.ranyhomemade2466]

I like your DIY and technique machine how to make it, mine mostly by handmade

[@GBWM_CNC]

@@mr.ranyhomemade2466 I see. :D Good work bro

[@jimmym2719]

Very well done 👍, I am ordering the Sanou chuck gonna make one like yours😜, thanks for sharing 💕

[@GBWM_CNC]

I'm glad you like it 😁

[@jimmym2719]

May I know which model Sanou chuck u r using? May I know if I use Nema 34 for spindle ok?

[@GBWM_CNC]

@@jimmym2719 The chuck is K11-130 By nema 34 you mean a stepper motor for spindle drive? I don't think it's a good idea to use a stepper motor for it if you mean that. Those usually spin at low speeds and these are ill for an disease called loosing steps.

[@jimmym2719]

@@GBWM_CNC ok for not recommending Stepper as spindle. thanks. I ordered K11-125..too fast,haha. Your video is helpful 💕👍

[@cr2fabrication]

Nice work my friend!!! Needs a servo motor for the spindle!!! :)

[@GBWM_CNC]

Hell yea!

[@davethurston753]

Looking good. Is it possible to use a stepper motor to turn the chuck?

[@GBWM_CNC]

Not the best idea imo. Under load stepper motors sometime are loosing steps which leads to motor stalling.i would't recommend

[@luboshcamber1992]

Hey man, awesome job indeed. I wanted to ask you about your chuck. Are hou you happy with its quality and where can it be bought? Thanks, God bless

[@GBWM_CNC]

For now seems to be not bad. I've got about 0.02mm runout but thats probably the failure of the bearings i used. Its a k11-130 from aliexpress. I paid for it about $50-60

[@thanhnhanhuynhnguyen3652]

Well done! Do you have any plan on changing the bearing? and what would the replacement is?

[@GBWM_CNC]

I was thinking about tapered roller bearings. But having extra time to make such upgrade is quite necessary.

[@Cjephunneh]

very good work. to get better results you need to increase RIGIDITY. You only need to double the steel plates for the chassis and may be install larger bearings.

[@GBWM_CNC]

Which steel plates you mean?? The plates where os the spindle mounted? I think the biggest rigidity loss is on the rail blocks.

[@TheGonzov]

Very Nice, congratulations! I think the same the rigidity is the first thing to look to upgrade a lathe, maybe some reinforcement plates inside the "box" of the spindle? "the more mass you can get the better results you can get" 👍 think is steel and the steel transmit more vibrations than cast iron (the reason why almost all the lathes and industrial sewing machines are made of cast iron) but is not a "problem" you can do an awesome machine any way, by the way you already get an awesome machine! thanks for the video, I almost forget the bearings, the conical truck ones you can preload are one of the best options, bye and TKS again.

Incredible! 🤩

Ficou muito bom o seu torno.Voçe usou eixo linear de qual diametro.Estou pensando em fazer um cnc pra mim e estou na duvida entre eixo e regua linear qual o melhor.Ja que a diferença entre um sistema e outro é bem grande

[@GBWM_CNC]

Você quer dizer os trilhos? São 16mm. Mas para meu próximo projeto usarei trilhos definitivamente lineares como os HGR - muito mais rigidez.

[@wladimirlopes5841]

@@GBWM_CNC Opa muito obrigado pela informaçao.Me ajudou muito ,eu também estou pensando em usar o HGR 16 .Acha que ja é o suficiente .

[@GBWM_CNC]

@@wladimirlopes5841 Depende de quão duro você vai empurrar sua máquina. Mas pode ser uma boa opção 😁

@@wladimirlopes5841 Eu acho que o HGR16 deve funcionar bem.

[@KenzoAkihiro]

Un gran trabajo, pero tengo una pregunta.... Con esos motores eres capaz de hacer roscas tanto de métrica, imperial, etc?

[@GBWM_CNC]

En 1 o 2 semanas estaré trabajando en la función de mecanizado de roscas. Pero el sensor en el eje debería dar la posibilidad a cualquier rosca que utilice motores paso a paso habituales en el eje Z / X.

[@KenzoAkihiro]

@@GBWM_CNC Tengo que ver todos tus videos y ver el sistema x/y que has puesto para el torno. Yo queria comprar uno pero trabajo en el metal y bueno.. si puedo hacérmelo. Y no es que vaya usarlo a diario pero hago mis cosillas, Y para las motos, el rc y cosas asi me vale.

[@GBWM_CNC]

Compruebe, tal vez encuentre algo que le sea útil :) Para trabajos pequeños, creo que un torno de este tipo puede cumplir con las expectativas, si los materiales procesados ​​no son demasiado duros. Ya es posible trabajar en acero dulce.

[@KenzoAkihiro]

@@GBWM_CNC Bueno voy a por algo como lo suyo hehehe, va a ponerque tipo de electronica usa? tarjeta, motores, etc?

[@GBWM_CNC]

@@KenzoAkihiro Solía: tarjeta de control paralelo CNC Motores paso a paso de 2,2 Nm y 3 Nm (ejes X y Z) Controlador paso a paso M542 y TB6600 (pero recomiendo DM556) Fuente de alimentación de 25,5 V (pero recomiendo un voltaje más alto si sus controladores son capaces). Principalmente usé productos electrónicos que quedaron de proyectos antiguos

What a GREAT JOB; You will sorry me but I MUST COPY THIS MARVELOUS CNC LATHE, with your permission; or without it....Thanks a LOT

[@GBWM_CNC]

Haha thank you! You're welcome. I did also copied some solutions from other people. It's pretty common in engineering community 😁

@@GBWM_CNC Don't worry, when mine will be finished (some time in this century) I will mention yours as my inspiration... great advance over the "Learn ...." version About the NEMAs and drivers, and belts... etc, where did You get those? Thanks again, in advance

Cześć. Możesz podać orientacyjne wymiary. Długość i szerokość łoża oraz jakich wałków użyłeś, 20mm? Pozdrawiam.

[@GBWM_CNC]

Cześć. Łoże ma 1000mm długości przy czym prowadnice na łożu mają 800mm długości i 16mm średnicy (trochę żałuję, że nie 20mm). Szerokość łoża 240mm.

[@kamilbabiarz1101]

@@GBWM_CNC nie widziałem nigdzie na filmach. Obrabiałeś jakoś powierzchnię pod prowadnice. Teraz jak masz czym dotocz sobie nowe wrzeciono. Wyrzuć też łożyska samonastawne a w ich miejsce dopasuj stożkowe. Powinieneś bez problemu znaleźć takie które będą górnym wymiarem pasować w te obudowy.

[@GBWM_CNC]

@@kamilbabiarz1101 Niestety nie miałem możliwości obróbki powierzchni pod prowadnice i jestem tego świadomy, że jest to błąd jednak w ramach testu postanowiłem sprawdzić co z tego wyjdzie bez takiego zabiegu. W ostateczności biorę pod uwagę dołożenie precyzyjnej płyty aluminiowej pod prowadnice jeżeli będzie bardzo źle. A co do łożysk to właśnie od początku brałem pod uwagę właśnie aby coś takiego wykonać. Jak będzie czas to będę myślał nad modyfikacjami 😁 Dzięki wielkie za wskazówki

[@antoniomorais6380]

Ficou muito bom seu torno eu também montei um mecânico não CNC só que tem vibração ficou muito leve o carro principal estou pensando em colocar um parafuso preso no carro principal com 2 rolamento deslizando na base do torno com uma porca parlock espero que dê certo

[@GBWM_CNC]

Deixe-me saber como ficou

[@ElixirCNC]

Awesome! Nice work. What was the cost of this project?

[@GBWM_CNC]

Thank you! At this moment a bit less than $1000.

[@ElixirCNC]

@@GBWM_CNC Nice! I have spent about $2800 on my Harrison M280 CNC/Manual lathe.

[@GBWM_CNC]

@@ElixirCNC Your Lathe looks much sturdier than mine. I saw your videos 😁

[@ElixirCNC]

@@GBWM_CNC I agree, I'm glad I bought it. It definitely performs better as a manual machine though. This machine actually lacks ball screws although the compensation in LinuxCNC makes that not a problem.

[@GBWM_CNC]

@@ElixirCNC I wanted to build mine from the begining to learn a bit about how everything works so I'm happy with mine too😁 ! I encountered some backlash problems with my timing belt driven axis - about 0.05mm like on the video. I will have to play with the compensation tool - hopefully it will decrease the error like you did on LinuxCNC.
