How To Make a DIY CNC Metal Lathe with Threading Ability

[@YippeePlopFork]

Mate, this is frankly astonishing. At several points, I thought "no way is that going to be square". firstly, I was sure that the frame wasn't going to be perfectly square, which would throw everything else out....then I was sure that your head stock construction wouldn't be perfectly square....and so on, right until the end. You must have some master craftsman level skill to pull all of that together and for it to work so well. And the double kick in the balls to us newbies is how fucking great it looks too! I watched the "Lets Learn Something" video on making a lathe and I thought the same thing about his construction....you guys must have some sort of extra instinct or special power to be able to put raw steel tube and plate together and it all end up square... Bravo!!

[@GBWM_CNC]

I'm glad you like it 😂Nah, but seriously - everyone knows it can't be PERFECTLY square. But at this point I think it came up pretty great. Measuring the angle between the spindle axis and Z axis in vertical and horizontal direction there is no visible angle in the horizontal plane and verticaly there is about 0,02 degree. I've spent some time adjusting it and I wasn't able to make it closer to zero. This makes about 0,08mm difference on the whole working space (using a dial gauge for measurements) if you measure the diameter of a 30h6 cylinder. Runout on the spindle - 0,03mm - pretty good in my opinion for such bearings used IMO. Let's learn something inspired me to make such a machine and I'm really happy with it - it's not perfect but for hobby use in my workshop it does the job. Thanks for watching! 😄

[@CleoKawisha-sy5xt]

all the parts and metal must have still cost a small fortune, no ? do u think it was worth it, or was it more about the journey?

[@Biokemist-o3k]

New subscriber here. I acquired an older lathe that was cobbled together from a couple other ones just so I could have one to make parts for my small engine repair business on. I deal with lots of obsolete motors and machines. I need to modify my lathe to work wit a stepper motor such as the one you have here in this build. By the way Fantastic work my friend. I am recovering from a horrific accident that happened a little over 18 months ago on my 1957 Harley. I can walk now but it is time to get back to work and start the business soon after. The ability to program will be indispensable. Thank you, John

great build and nice color choice, my tools are all Sublime Green Metallic. I didn't think a homemade lathe would be a good idea due to complexity but this shows that if you build it as a CNC with a digital motor from the ground up then you may omit the complexity of speed changes and threading gear boxes. I will try this myself rather than converting a Grizzly lathe

[@GBWM_CNC]

Thanks! This is exactly right - the complexity of a gearbox would make it much harder. But a simple VFD / encoder and CNC controller does the job just right :) But stiffness might be the problem. You should consider converting a Grizzly lathe with adding the CNC aspect which might be a good idea

well it's a lathe kzbin.infoUgkxN9zrzkkhnjUF5PQbuA_B1gYdsfCu9k6z but it wasn't what i would have anticipated. Headstock, tailstock, carriage apron are manufactured from aluminum now not cast iron. The spindle diameter for the bearings is too small allowing for a few play in the spindle so I am using some blue Loctite to take out the play.

A lot of hours condensed into just over an hour, end result looks great. My only thought maybe the tailstock may be a weak point, a lot of overhang may give rigidity problems, you could help this slightly by putting in a diagonal piece from the tip to the base although the most stiffnes is needed in the front to back plane.

[@GBWM_CNC]

Haha, it was a lot of work indeed. You're right - the tailstock isn't as rigid as it could be. A diagonal piece of metal could be quite necessary here. I''m really glad I'm getting so many comments about what upgrades I could do here. When I'll have some spare time I'll think about making some upgrades on the lathe making it more usable. Thank you!

Epoxy - rock mix would be a good idea for vibration damping. But at this moment i need it to be mobile as i have lack of place as well so sometimes i have to move it a bit and mass wouldnt help here 😁

The headstock could be stiffened with steel plates. Welding metal to the outside risks heat distortion but bolted on plates might help.

Do you think the carriers make to much chatter or would you go with a different kind in hide sight, to turn the chuck on, for what it has to carry, the inertia and speed it turns or do you think what you have is good, even better then you thought, your thoughts would be appreciated thanks brother

[@GBWM_CNC]

Next time if I make a next lathe (probably i will do) I would use shaped linear rails like the HGR series for example - these are MUCH more rigid for a bit more money. But it will be worth it. The bearings for the spindle are not the best idea too - roller bearings would be nice with a stiff housing. It would prevent a lot of chatter. The downside of roller bearings is that you've got to have a lathe to make a proper spindle shaft (I didn't have at that time so I had to use usuall pipe or pay a lot for making a shaft and the purpose of this project was to make it cheap :D ). These are my thoughts after making it. But anyway if I make light cuts it allows me to make a lot of operations.

It does in aluminium pretty well and soft steel like s235 with shallow passes. It supports "manual" but it works like - press arrows to go where you want. There are no handles but you can controll it manually from the keyboard. At this moment there is only a step file for it as I can't find time to make fine instructions for it. Maybe during this holidays I'll have some free time to make it.

The free version doesn't allow to do threading operations. If you buy a license you can do threading and run GCODEs with no lines limit (I don't remember how much exactly is the limit for the free version). If you want threading - I would recommend LinuxCNC which allows to use incremental encoders for your spindle.

@@raislr3519 So if you want to do threading - I suggest you to get familiar with linuxCNC. It's free and can be used on most cheap CNC Breakout boards which use the parallel port of the PC. My lathe uses LinuxCNC. For threading you need an incremental encoder which will be connected to your spindle shaft (this sends the spindle rotation information to your controller allowing your to synchronise your X axis with the spindle movement). Check out my other videos - I did some videos about threading on a DIY CNC Lathe :) Maybe it will help you out. If it comes to knurling - I have no experience here but I think you will be able to easily get through it :) edit: At the begining LinuxCNC seems to be hard to configure but it is really a powerful system (and it's free!)

Lots of work into building your own lathe, well done. Few tips to improve. Weld a couple of rods in the head and fill the head with epoxy granite to reduce chatter from the head. Second fill the tubes on the bed also with epoxy granite as your lathe does not have enough mass currently and can clearly see from the video you are having chattering issues from lack of rigidity. It should improve the cut quality by a significant amount. The apron will be a lot of extra work to improve rigidity as you will need an extra 3 rail because you didn't go with linear rails that causes small movement in the apron from using round rod rails. Other than that this was a lot of work. Not a lot of people build their own lathe.

In using a closed loop stepper motor to get the sync with the other stepper motors (closed loop) if using a a non-synced spindle drive motor.. of course the 'sensor stepper motor should be configured not to be power driven and the fault line not used and you may want to size the stepper to be big enough for slow machining.. and install a brake system of using a milling attachment on the lathe post.

Fantastic build process. It looked like you had an auto-darkening shield for your camera on some of the welding footage. Spare welding mask? Great idea LoL. A few things confused me. Why such a large motor for this lathe? I read what you said about why you built the headstock with those bearings, but I figured that you'd quick be turning a new spindle and converting to preloaded tapered bearings. The next thing was the size of your cross slide and carriage. How big a swing do you have? In the end it seemed like a waste of expensive precision plate. As things proceeded early on I was thinking you were building a larger lathe and then was confused by the Z axis rails. The cleverest ideas though.. grease fittings! Yess!. A tool post and collet chuck side by side! Another great idea for working small parts. Ok.. so you are making some use of the extra travel. LoL. Since you're all CNC perhaps this is more useful being you can go back to exactly center the collet chuck. I did notice your first cut of the spindle mounting plate your tool was way off vertically. Then you fixed it later in that sequence. 😂 I was wondering too about the bed when saw the C channels being welded. I was thinking.. that's NOT flat enough by any means. I was waiting to see your "flatten the bed" sequence with you scraping the bed flat and checking it against the spindle axis. I was expecting a flat plate or at least scraping the bed to get it close. Alas, aluminum rails will never be rigid enough so it probably didn't matter that much in the end. Still a heck of a build. Congrats! I'm contemplating something similar. I was thinking DROs and steppers. Are you calibrating the CNC software off of the limit switches? Is that sufficient for accuracy? I'm very curious about that because you aren't using synchronous motors. CNC without DROs would save quite a bit on the budget! Thanks!

[@GBWM_CNC]

Oh, that was an detailed analysis! So... I have dark welding glasses just for the filming purpose. That motor was so big to have higher torque on lower RPM for threading while using a VFD (without no additional gear-reductions). At first I was about to make a new spindle soon after making this one... But after figuring out how many things I'd like to change - I decided to make a completly new lathe with the experience gained with the first one. Yeah - the precision plate was quite but - mainly to have the additional tools chuck. Btw you're very observant! Yes - I had to adjust the height after the first cut, lol! And you're exactly right - those rails were not rigid enough to work very well in the end but that was quite good to mount them on the C-beam surface. But in the end the precision on the whole length was really good to be honest (in my opinion). About calibrating - depends on your accuracy needs but I'd rather set the work coordinates from your stock after the first manual pass (that's how I do it). After that I'm set for what I needed. The stepper motors with the right drive setup should work well unless you're aiming for microns - then you will need some kind of DROs th chase the microns which run away for example when your ballscrew heats up. There are many variables there! :)

[@Jocanguro]

Great work, but is it all controlled by PC? Even the filleting routines? you give him the shape of the piece and he does everything? Congratulations,.. very good!!

[@GBWM_CNC]

Yes it is controlled by PC with LinuxCNC. All the motion is controlled by it - any pre-designed part which can be made by a lathe. Glad you like it! :)

[@luboshcamber1992]

Wow man. Beautifully done. One comment and two questions. When nig welding you don't have to wiggle your torch left right, only for bigger gaps. Question is. What is the runout on the spindle? Is it heat treated? Thank you, God bless. Greetings from Slovakia. 🙋

[@GBWM_CNC]

I think it is not a mistake to wiggle it a bit anyway? But when there are big gaps then it is pretty handy :) About the questions - spindle runout is about 0.03mm. Not that terrible if you know what kind of bearings are up there in my opinion 😅I didn't heat treat the spindle. For workshop it works just fine. Thanks for watching and greetings from Poland! Stay safe

Qual deles?

[@be007]

doesn,t those linear bearings make the lathe shatter like hel ? i mean, there is totaly no demping effect, like a standard lathe from cast iron and a lot of mass ?

[@GBWM_CNC]

Probably the linear bearings are the problem. BUT - there depends a lot on the feeds and speeds, depth of cut etc. I was able to cut steel on this lathe with lower parameters and aluminium with 0,5mm DOC and 0,2mm/rev and cutting speed ~120m/min which worked pretty well with almost no chatter. But you're right - there should be more mass and something filling out the sections not mentioning the linear rails as guideways. This had to be a CHEAP project and actually it was and I'm able to turn soft steel and aluminium at home which was my main object. Thank you for your input - appreciate your comment :)

ММММ! ЖЖЖЁСТКОСТЬ!!!! А какая точность!,,,, ВЫ должно быть об-лись веществ неведомого происхождения? Иначе как под веществами, никому не придёт в голову изготавливать такую хлипкую на кручение и изгиб раму, и ставить на шпиндель обычные подшипники, вместо особо точных

[@MrFastFarmer]

This is a fantastic effort, but without seeming negative I have a few concerns. You should use tapered bearings on the spindle so you can take out the runout. Alignment of the saddle to spindle seems to be missed? Mounting the rails should probably be the last job so you can ensure true parallel. A lot of cutting force is going to be on the rails pushing on one side and lifting the other. I think a heavier flat guideway would be better. It’s worth noting good lathes have weight in the saddle and stand for a reason, which would also help your design.

[@GBWM_CNC]

You're right. This is actually my second machine I ever made and I know it's missing some things. It had to be as cheap as possible which lead to the UCF bearings instead of tapered ones (the main goal was to make this machine without having access to an other lathe or milling machine). Same with the rails - next time I would definitely add a bit $$ and buy at least the hiwin style rails. To sum up - I know there are some mistakes, but in the end the lathe does what it should for really small amount of money (in my opinion 😁). Thanks for the comment.

[@robrob5419]

It's great work and a lots of ingenuity. The only thing is, why does everyone posting a machine building video feels obligated to add a music background?

[@hikolanikola8775]

Did you just make a servo out of old AC motor with using just an encoder?

[@GBWM_CNC]

Well, I can't say that. The ac motor spins it by itself ale the stepper motor synchronizes the motion to it. The encoder doesn't impact the ac motor speed. So we can't say it works exactly as a servo. But yeah, the system gets the feedback from the encoder just like in a servo

[@noodlesiis]

Question oh man behind the mask.. Are you an electrician? I think i could build a similar lathe to a good standard as an engineer but the stepper motors and all the wiring… woo not me.. Fantastic work though beautiful job..

[@born_to_be_wild_]

Выглядит здорово! Остались вопросы: 1. Какое биение патрона получилось? 2. Какая жесткость станины на отгиб? на канале Special Instrument Designs есть методика измерения. 3. Что получилось по стоимости? 4. Какие недостатки после года использования? Поделитесь, пожалуйста, результатами

[@GBWM_CNC]

1) Биение шпинделя 0,03 м. 2) У меня не было возможности тщательно изучить жесткость системы. Может быть, когда-нибудь будет шанс. 3) Стоимость около 1300 долларов (примерно 2 года назад) 4) К недостаткам можно отнести конечно низкую жесткость системы, при токарной обработке стали не всегда достаточно, но для небольших гаражных работ сойдет. Все работает как в начале, потому что пользуюсь изредка, поэтому не изнашивается.

Great work! How did you check straightness and parallel of slideways?

[@GBWM_CNC]

parallelism was checked with a dial indicator attached to one of the linear bearings and I measured the opposite rod if the distance is the same on the whole range of motion. The straightness - you mean if the height is the same everywhere? if yes - here is the problem. I trusted the c-beam (on the Z axis) and there are little off-sets sadly. The Z axis was mounted on a flat face milled plate so it should be right :)

Notes to myself about building my own lathe: - Myself, don't try to build a bed from square tubing, the tolerances will be to much. - Myself, don't use these pre-fitted bearing-blocks on spindle, they are noisy, even when brand new. - Myself, don't use these linear-rail-thingies (amzon specials), they are noisy and rough. - Myself, don't use a 2KW motor, if that thing doesn't kill you, then the high voltage will (400V). - Myself, don't buy a precision aluminium plate and then hammer on it, it won't be "precision" any longer. - Myself, f$!k that computer-shit, I wouldn't know what to do with that (to old to learn). - Myself, ... SHUT UP, don't spoil the fun for this lad here who must be very proud of his creation ! Okay, but uhm ... Myself, don't drink weird juice from funny wooden bowl, it might change your opinion about "Notes to myself " ! Note to young lad (GBWM): Hey Mister, the generated chips is something to be proud of, because they are the evidence that you have been working hard. Don't try to hide them with some weird "guards". Besides you need to clean the whole lathe anyways, so a few chips here and there wont matter. And I finally do also have something nice to say: I like that idea of a fixed shaft in "Bohrerhalter" = Simple and efficient. That would be good enough as my tail-stock (for my intended purposes). The end-result of your lathe is really cool 👍 Wir sprechen auch Deutsch 😁, wofür steht "GBWM" ?

[@GBWM_CNC]

I'll take this comment as a suggestion that i'm crazy. Agreed, haha! The notes are quite good though. I'm really proud about the chips and yup - it was a lot of work. GBWM bedeutet - GB bedeutet mein Geheimnis und WM bedeutet Schweißbearbeitung (Welding Machining) :)
