Home Made CNC Milling Machine

[adeyltonnsilva]

hey i'm brazilian too! i'm building a cnc but for now it just cuts sheet metal with a cutting disc instead of miller. what softwares do you use to control the machine?

and congratulations. very well done!

[rbardelli]

@adeyltonnsilva Turbocnc or Mach3

[sla165]

Уважая немцев за точность и дотошность в технике,в лепешку расшибутся но сделают так как надо.

[rbardelli]

@sla165 Yes, it will make the cake :-)

[sla165]

@rbardelli What do you mean cake? I wrote about the technical achievements.

[rbardelli]

@sla165 Im Sorry. I had to use the Google Translator to translate that russian sentence. Then google told me that you said something about that this machine is not so precise as a german machine but It will do the cake..., sorry.

[sla165]

@rbardelli And, there's nothing.Got you.Do not strain, it's Google translator translates strictly according to the meaning rather than phrases.Hence the difficulty in understanding the translation.So all the way through.By the way you are from Brazil? How are you?

[rbardelli]

@sla165 I got the right meaning. Yes, Im from Brazil but Im living in Norway, not so that far from Russia, and Im doing very well

[sla165]

@rbardelli What are you doing in Norway? Ibid cold? Well, compared to Brazil? Or Brazil's difficulties with the work?

[rbardelli]

@sla165 its not very good to work in Brazil. Thats why I moved to Norway, in less than 1 month I was hired to work for a big company here to do real engineering...

[sla165]

@rbardelli That is, you're an engineer? In what kind of area?

[rbardelli]

@sla165 Mechatronic Engineer. Here in norway Im working with industrial controllers.

[HeadShot360IN]

how much friction can you have on the rails so that the stepper motors are strong enough to move it? Example: If you dont have the lead screws hooked up, how much force should it take to slide the table and such?

[rbardelli]

@HeadShot360IN . To calculte the torque(We dont use the word FORCE for motors) you have to know how much Mass the motors will have to carry and what are the Inertia Momentum (geometry) of the load . With this information you can calculate the torque needed to move this load, and with the datasheet of the motor you will can see what will be the maximum speed for that torque. 

[rbardelli]

The calculation of friction is not a exact science. Its almost impossible to calcule without having more data.

[HeadShot360IN]

@rbardelli well, i'm not asking for mathamatical numbers and such, just something along the lines of: If you try pushing it with your pinky, do you have to use alot of effort? or does it require you to use TWO hands and put your whole body weight into it.

[rbardelli]

@HeadShot360IN If I disconnect the motor from the screw , the gravity will push the Z axis down and if I incline the machine 15 graus the gravity will push the others axis to move as well... So you dont need to make almost any force to make a movement in the machine without the motors been connected...

[HeadShot360IN]

@rbardelli okay, i get it, thanks

[xlrationmarine]

WHAT????

[KrausemMatsumura]

Excelente Trabalho parceiro. Excelente. Estou no japão agora e estou começando a projetar uma CNC para meu próprio uso aqui. Esta vai ser a minha primeira máquina com esta função.

Vou me inscrever em seu canal e ficar atento ao seu trabalho.

Parabéns!

[KeithWasHere1]

damn thats beautiful.

[MetalChaos0]

cover the control unit because if a shaving of metal or if you are using oil it would short circuit and burn a part out even if its just something like covering the boards with a blanket 

[nvirus77]

Precission Profile Rails On the AIR !!! GGRrrrrrrrr :(

[douro20]

Are those roller guides or recirculating ball guides?

[rbardelli]

@douro20 These are recirculating ball screws

[wa1523]

you should use ball screw to go even faster

[rbardelli]

@wa1523 These are recirculating ball screws

[milek021]

Nice, 750W, Makita GD0800C, nice tool but too loud :) If u are making more cnc I recomend U to chage that Makita with Bosch GGS 27 C or all so Bosch GKF 600. Cheers

[rbardelli]

Its not really a toy. Its a very precise machine and I sold 5 units of this machine for several jevwerly industries.

[kw757]

That's a lot of work for a toy machine!

[silva1320]

Amigo. Qual o preço total das peças para montar uma cnc igual?

[rbardelli]

@silva1320 Só em peças, em torno de R$8 mil. Fora a mão de obra usinagem de algumas peças.

[peterlonz]

Beautiful job. I'm impressed with the speed of positional movement.

You don;t tell us the output torque or give any practical indication of spindle HP, so how can we know what this machine can do or what it was designed to achieve?

I'd also like to know whether the axis drives are by simple threaded rods & if so what accuracy can be maintained & how much cleaning of the drives is necessary.

[rbardelli]

@peterlonz Im using a 1 HP spindle. The machine is made of very precise threaded rods. I can achieve 0,05 mm precision.

[JordanianPride80]

am building my own 5 axis cnc arm since 2009, but am stuck with electronic part..i can manually move it in the desired directions but can't do that electrally...i lost motivation 

[rbardelli]

@JordanianPride80 You dont need to do everything. You can easely find the eletronics on the internet. I really recommend to buy Gecko Drives , Google it.

[youtship]

What drill head did you use?

Seems it can produce very prependicular & sharp edges.

[rbardelli]

@youtship Im using a Spindle manufacture in my home country (brazil)

w w w .t e c m a f . c o m . b r

[sxyuklad1]

what are your electronics may i know please?

[rbardelli]

@sxyuklad1 I bought an electronic board from my friend here in Brazil but I also used gecko drives in other machines. Search fo Gecko drive in google.

[rbardelli]

@sxyuklad1 I really recommend to buy Gecko Step Motors Drive , google it,

[5WED]

(part 2/2)

however just a miserable finger touch on the one end was enough to make them "even". therefore the steel is too mild (although file-hard!!!) to mount the rail on the two end-points.

instead, I recommend continious or multi-point undersupports.

the design of the milling machine still allows such modification.

and more: use 4 carriagies on the X-pad to deconcentrate the downforce on the rail...

good luck!

[5WED]

(part 1/2)

i'm kind of surprised - "the best cnc milling machine that the author has ever built" has an X-axis hanging just on the 2 (TWO!!!) carriages and rails supported on the ends only... honestly, this is very, very bad solution because X-pad is definetely going to sag in the middle! I'm saying this since I took 2 brand new HIWIN rails about 1 meter long, put them together and they did not touched upon each other along all the length of the mouting surface - they were slightly uneven.

[Schinfo]

Gastaste quanto? Por quanto você constrói uma?

[rbardelli]

@Schinfo Sem contar a mão de obra envolvida, em torno de US$ 5000 em peças.

Nao estou fabricando mais esse tipo de máquina.

[cedovem]

gives a look at this test

[gavilan1122]

buen trabajo !! excelente !!

[partyboy93]

Whitch model of gridner do you have ??? Is it 750W or 400W ??? I'm making a small non cnc milling machine. Would be 400W enought power ???

[rbardelli]

In this machine Im using Makita brand Grinder 750W. For my newest machine Im using a professional spindle 1500 W

[snake9510]

i can just recommend using professional hf-spindels... the noise of these grinder ''spindels'' is just insane- also in the case of Kress products your wallet will feel kinda light after purchasing one.

also many professional spindles have a signal output for the actual speed;-)

[rbardelli]

@snake9510 I Agree with you but as you said: it cost a lot and its very hard to find it here on my country

[snake9510]

kk, they are expensive, indeed... and makita supplies really affordable productsXD

guess its kind of a no-brainer then

[sc0rpi0n0]

@snake9510 I disagree, the sound is robot-like sweet.

[ZeDuBreju]

Opa! Amigo eu não entendo muito de máquinas, mas essa ai que tu fez é uma fresadora? Você é engenheiro ou algo assim? Belissimo trabalho!

[samuelluthier]

viva os smiles! é um driver sem comparação realmente.

muito legal sua maquina.

[rikirikado]

Isn't that German?

[rbardelli]

No. Its Brazilian Portuguese...

[pingpongme]

Finally a video were someone actually talks.... too bad the only Brazilian i understood was the word Makita.

[rbardelli]

Sorry. I have plans to make this video also in English but I need some free time to do it and Thats it the problem

[aussienerds]

Haha me to.

[molinobeer]

@pingpongme

actually it's portuguese, not brazilian.

[FarmMachinist]

...that no a CNC mill ... it's a CNC router :O)

[Axel2989]

Wow this is very expensive!

I found exactly these aluminium profiles on the junkyard for 20$

Maybe you could use Steelplates unter the fences like i do, but the plate need to be really heavy an absolute straight.

[rbardelli]

This is one of many disadvantages to live in a country wich citizens only think in soccer , carnival and beer...

[boxa888]

wow thats awesome! really awesome great work! what program do u use to run it? awesome!

[rbardelli]

I use a program called MACH3

[molinobeer]

I think you are runing the drill to fast, it's producing alot of chips.

What are the drives you use?

[Axel2989]

support the fence of the table! it would give you 200 percent more stability. PLEASE

[rbardelli]

Hello Axel.

I Know you're right, but the purpose of this machine is for hobby. I live in Brazil and its very expensive to make a machine like this one because all parts are imported from other countries. If I have to support these fences I would expend more than US$1000 and because of that I decided not to support.

[locao010289]

excelente trabalho! já tentou fresar aço com a furadeira utilizada? funcionou? qual o torque dos motores de passo?

[rbardelli]

Olá. Sim, já coloquei essa máquina para usinar aço 1020 e ela faz sem problemas.

abração

[adisharr]

With all that extrusion, you should really support those rails. Profile rail is not designed to be mounted that way unlike round rail.

[merdamerda3333333333]

que tipo de fuso foi usado no eixo Z e qual é passo e o Ø?

[rbardelli]

Foi usado um tipo de fuso retificado.

Diametro 12 mm passo 3mm

[tommee10533]

And are those NEMA 23 motors?

[rbardelli]

Yes.

[tommee10533]

Hello, what type of motor are you using for the spindle?It looks like a die grinder.

[JTMarlin8]

The unsupported linear guides on the Y-axis are ridiculous.

And I mean that in a bad way.

[rbardelli]

But it does the Job.

[motorbikefliptrick]

yeh i didnt relize that untill i read your comment it is pretty silly

[yorrickhunt06]

why single out the y axis in particular? the whole thing is mechanically an ablortion, but at least it was cheap.... at least I hope it was cheap

[JTMarlin8]

The other axes use round linear motion rails that couldn't be supported even if he wanted to.

The Y-axis use rectangular profile rails that are drilled and counterbored every 60-80mm.

[Akura02]

Impecável. Parabéns.

Já estive para montar uma também, mas não consegui encontrar os drivers e de electronica eu não percebo nada.

[BigCockvanHugenDong]

thats great, although what is the most difficult metal you can mill on this?

[rbardelli]

I never milled anything harder than 1020 steel but the machine mills 1020 steel smoothly. I think the machine is capable to machine 1045 Steel and even more harder materials.

[sharadeth]

aside from my fear of having exposed wires this looks very professional nice job!

[rbardelli]

There are no problems to Have these exposed wires because they are all Low Voltage.

[PLSteamer]

Muy bien!!!

[tbenefi33]

Nice cnc machine

WISH THIS WAS IN ENGLISH

[donnyab]

repost in english please !!

[rbardelli]

Essa do video saiu R$12000.

[raphaluiz]

completa? e vc fabrica pra vender? como é?

[raphaluiz]

e essa máquina trabalha com quais materiais? tamanhos etc...? Obrigado

[raphaluiz]

Quanto custa uma máquina como essa aqui no Brasil? Obrigado

[rbardelli]

Olá, por que quase ninguem tem dinheiro para comprar aqui no brasil eheh

[MESTREVIPER]

vc e genial! pq n vender?

[TRILLO04]

Parabens, Legal ver pessoas fazendo bom uso de seu tempo e compartilhando seus feitos afim de inspirar outros. Que tal ensinar a gente como montar uma???? :-)

[neilendrigo]

Nossa, parabéns =)

 quero ser como vc quando crescer =)

[sanmotta]

tava tentando montar uma

ond conseguistes os drivers?

ja achei os motores de passo

valew!

parabens!

[rbardelli]

Eu tenho um amigo que está fabricando esses driveres, eu comprei dele. O problema é que ele demora um pouco pra entregar, cerca de 3 meses.

abracos

[hansvledder]

Excellent achievement! Would love to hear your explanation in English.

Best Regards,

Hans

[NickBlackDIN]

looks great!!

[cncmania]

Show de bola!!!
