How I Built My Own CNC Mill

[@coltondillon2380]

I love this so much! I work with CNC machines for a living and this is so cool to see. One recommendation I'd have is use this to cut up some aluminum heatsinks and attach them to the outside of your spindle housing. That will make the coolant more effective at reducing that heat. A second idea is to just add a filter screen like cheese cloth to keep bigger chunks of chips out of the coolant filter box. I don't want to say too much and make this sound too critical of you. This is amazing and honestly a dream for myself and many other machinists to do what you just did.

[@xyzspec82]

I like the heatsink idea 💥🤓

[@EDCMaker]

Thank you very much! I always welcome new ideas!

[@revtmyers1]

I have seen a lot of builds, and many of them are nice, but this is definitely one of the best ones I've seen. It's taken the typical home built to another level. Very well done.

[@EDCMaker]

Thank you!

[@PiefacePete46]

It took the KZbin algorithm too long to offer me your video, but I am sooo glad it did eventually! I sat here, transfixed through every second... just fantastic, thank you. Liked and Subscribed.

[@EDCMaker]

Thank you very much!

I've seen a few diy cnc builds but yours is the best of them all.

[@nickp4793]

Great work on this mini VMC!

[@ericlotze7724]

Really well made machine, and video! Also don’t be to hard on yourself, if anything pulling off a machine like this with the tools you had is a compliment! You earned a subscriber for sure.

[@ChungvuiminMichael]

big respect to you. i am doing retrofitting an old cnc mill and having so much headache and seeing you done it, makes me so relieved that it is possible =) keep at it

[@Garageworkshop]

Incredible build! Amazing job!

[@codycox762]

Very nice craftsmanship!

[@kylejewiss659]

Sick machine! Well done mate!

[@mystamo]

Can't wait to see you make a tap wrench with that machine!

[@Dwarfgrinder]

Great accomplishment! If the spindle block allows, perhaps drilling through small coolant passages could be an option or adding a spacer cap to the top of bottom that has water passages to pull heat out may be a more optimal solution. I love that you came up with literally just flooding the whole spindle ! The simplest is often the best.

[@wadeskelton7585]

This was fun to watch congrats to you brother life should be a lot easier now 😃

[@HorizonMakes]

How, in God's name, did you have the budget to build this machine but not to buy a tap wrench 🤣🤣 Looking great, though! One of the better builds I've seen!

[@birdhouse2323able]

Very good build of DYI CNC milling mashine you used DDCS V3.1 as well for your mashine. You are happy with this Controller(DDCS V3.1)? I have also the same controller on my mashine and i am happy with it. Hopfully we will see more about this Mashine. You will finde my build also on youtube but it is German.

[@blackfoxmachining]

excellent work! I have built my own cnc mill as well. Would you be able to go into more detail on how you built the enclosure, coolant tray, and coolant system? Keep up the great work.

[@sgtpepperaut3392]

Cool build. Share your plans ? Pretty please

[@vizor4u]

Quick advise on the disk filter for the cooling system. It should point to the floor because when it collects the particles and it cloggs, you need to remove the disc but when you do that (with water off) and pull the filter, all particles go to the inlet and outlet. I had the same issue the first time I cleaned one of them on my watering system :D I guess you already figured that out tho

[@EDCMaker]

Yea, I noticed that. It’s rotated now, pointing the ground. Thanks for the suggestion though!

[@The_Seal77]

Would you share a parts list and possible cost for the parts for people that might want to build something similar?? BTW, awesome build and that is one beefy home made cnc. Just awesome.

[@EDCMaker]

Sorry for late reply but I have added a BOM to the video description. You can check out the parts list if you want.

[@randomrouting]

Nicly done!

Hola desde Venezuela felicidades excelente trabajo yo deseo hacer uno similar cuánto es el presupuesto para fabricarlo ya que traerlo de otro país sale costoso.carlos Méndez.soy fabricante de moldes en plástico PET para chocolates y hago una que otra máquina y me cae muy bien un CNC como ese está espectacular

[@alessiodinca2302]

Very good job! I would like to make one too but I don't know what components to use Can you link component you have used?

[@EDCMaker]

Yes! I have made a bill of materials. Its on the video description. Hope it helps

[@johannescordier7923]

Wow congratulations, I am subscribed. Can you make the tool changes faster with a drawbar ,pullstud ECT ECT ECT .( Asking for a friend )

[@EDCMaker]

Thanks! That’s one of my future plans. Currently the tool changes take up some time (not much but adds up). I have to think of a solution, because I don’t think these type of spindle blocks have enough space for a drawbar. I will look into some type of impact driver or simply wait to get a ATC spindle block.

[@alphouille6243]

green spindle unit is usualy done to go at a max speed of 3krpm , did you buy it done for a 8krpm ? or did you just go higher than it should go, and thats could explain the issue of overheating thx for the great content !

[@EDCMaker]

This one was advertised to do 6krpm, but yes I am pushing it past that, that’s why it is overheating. I will get some good quality bearings later and adjust the preload.

[@tiagolomar]

Really well made project….are you from Portugal 🇵🇹?

[@EDCMaker]

Correto!

[@bennyb.1742]

hi, i want to carve steel with cnc router, is it possible?

[@joergbeigang]

Nice build! And good to see this China spindle block in action. Thinking of getting one of those for a while now. At what spindle speeds did you experience it getting (too) hot?

[@EDCMaker]

Thanks! Everything past 6k rpm

[@m3chanist]

Very interesting driving the bt30 with one of those spindle motors, at 2:1 how is it performing? What materials are you cutting and is it giving you sufficient torque?

[@EDCMaker]

The toughest steel I milled was 1.2379 and it was fine. The spindle is performing pretty good

[@carlosmendezpernia8139]

En cuanto lo vende y dónde está ubicado

[@dirtboy896]

Love your creativity and fortitude but the aluminum extrusion as your column was probably not the best choice for rigidity.

[@amrsvn-uf2jk]

How much NM(newton force) / Kw of a spindle power as minimum required for steel milling process ?

[@Petriculas]

top xuxa

[@fehmiatas]

[@firukk]

Do you have any information about why the green part gets hot? Also, I think the sound made when the spindle is rotating is coming from the green part. Are the bearings not of good quality?

[@EDCMaker]

The spindle gets hot because the bearings are not good quality. And yes most of the sound is from the bearings

[@moathmomani2887]

What about the vibration? I guess the vibration is very high from its sound, and this is because all cnc builders on KZbin do not consider using damping material to reduce vibration. If you want to upgrade to to build a new one, I recommend building the structure from cast iron because the grains damping is high, and it will significantly reduce the vibrations so you will get better finish 👍.

[@EDCMaker]

It vibrates a little on high load cuts, but on finish passes its ok. Of course a cast iron base woud be much better but that would be much more expensive and this is supposed to be an entry/hobby machine.

[@rocketfuel-]

Hello, great cnc. Welldone. Are you happy with the spindle? I guess you bought it from aliexpress?

[@EDCMaker]

Thank you. Yes, for the money it cost its doing great and yes it was from aliexpress

This is sketchyness in gold hahahahahahahaha

[@calvinmoffatte7334]

Nice build, did you install a relay from the ddcs controller to the spindle vfd or wired directly?

[@EDCMaker]

It’s directly wired, the vfd as specific input for speed control

[@tfxreference8562]

were you cutting hardened tool steel or annealed tool steel?

[@EDCMaker]

It was annealed. Hardened destroys tooling even on a industrial CNC machine

[@tfxreference8562]

@@EDCMaker no it doesnt. Ive turned and milled hardened materials, incld D2

[@scavengers4205]

OMG!

[@ikbendusan]

just so everyone knows, you cannot measure perpendicularity like this at @ 7:00; even if that surface is not parallel to the dial, the needle of the dial will not move. this measurement is measuring the flatness of the vice which is of course surface ground, and therefore very flat. the dial indicator has to move along a reference surface that is known to be perfectly perpendicular to the datum surface

[@EDCMaker]

I was checking XY perpendicularly and I think this is the way you do it. I am assuming the vice surfaces are perpendicular. The dial is on a fixed position and not moving. Imagine an extreme case where the Y axis is 45 degrees to X: I align the vice on X (left and right) across the dial to make one surface parallel to the X axis and then without touching the vice, I move the whole thing in Y (front and back). Now if XY axis are 45 degrees, the vice will move sideways and the dial will show a lot of movement since it’s fixed. This is hard to explain but it works.

[@ikbendusan]

​@@EDCMaker i see. to me it was not evident from the video that you were using the vice as a square. we are basically in agreement then

[@ronin2167]

Where did you get a tool steel plate this big?

[@EDCMaker]

Got it from a supllier in my country

[@Sufian95]

You need a good quality magnetic drill machine

[@viktorfreeman3607]

Your typical mistakes as newbie in CNC building: 1. Usage of sand for increasing a rigidity of machine is not so bad idea, but if you want to get high value of it, please add some epoxy resin to it! Yes, it's hard to put this mix into metal parts, but it will give you a really good result. Simple sand filling will not work as well. 2. Power supply is not enough for fast repositioning. Your motors need 6A of current as NOMINAL power, but it takes approx. 2-3 times more, when it accelerate, or hold axis during machining. Just buy 3 pcs of 48V power supply with current at least 16A. This solution will gave you best results. No step missing, low noise, high torque. 3. Replace your spindle motor to servo motor. It will increase speed of machining, also your machine will be possible to make threads and this solution will increase depth of milling. 4. Good bearings will make your milling process more precise. 5. Put some noise filters to spindle motor and power supply.

[@crishawkins7359]

Number 1) The sand is NOT intended to increase rigidity at all - it can't. The sand is only there for DAMPENING! The steel and aluminum structure will ring like a bell. The sand will attenuate that very well, and will aid in increasing tool life. Number 2) You are incorrect and obviously don't know how stepper motors work. Stepper drivers are a current source and will not allow 2-3 times more as you state. Fast movement of steppers is reliant on VOLTAGE. Your suggestion for 48V at 16A will make no difference. Your other suggestions assume you know what the OP wants, it appears he has a nice machine and it works just fine. Your comment about his mistake is full of YOUR mistakes.

[@rorypeycha9700]

how much did it cost in total

[@EDCMaker]

I didn't kept track but probably around 5k euro

[@ericlotze7724]

I see you had a CAD File for the Project at 0:00-0:35, is that published anywhere already, and if not, would you be willing to post it on a “GitHub” / “Hackaday” / Wili page etc? If more and more people could build machines of this quality, imagine the things we can make/invent! Either way keep up the good work!

[@shrednem8806]

what ended up being the cost total?
