Presentation of my 5 axis CNC mill project where I answer some of the most common questions. More pictures to this project on my Instagram: / fabianbrock8
“I built this little 5 axis CNC machine... I have no professional background in engineering or CNC machine.” Absolutely incredible mate. New subscriber ✌🏻
nothing tells me more of an excellent engineer than when he shows his faults and how he plans on correcting them. we never get it right the first time.
WOW. I built my own 3 Axis a while back. That was already a challenge. 5 Axis was always in the back of my mind, but seeing your machine is frankly quite intimidating ;). Outstanding work!
5 axis will have much more outcome accuracy problems and errors, how much will you expect ? How much is it when machine comes back to 3 axis normal use
@@ray-charc3131 I don't know yet what to expect. A lot of it also depends on patience during alignment. And yes with 5 axis this process is lot more complicated. I will do a video about the assembly and alignment process with the results in accuracy.
@@fabianbrock since you do not operate a business and you built it as a project why not share parts list, detailed process, wiring guide and knowledge you gained from is genuis build This is a genuine question?
@@FirstLast-tx3yj I will do this later on. First I want to finish the machine to see if it works as expected. I don't want to put out a version now that might not work.
Thank you for sharing tis video. There is not many DIY projects out there that have such a good mechanical design as you have built. I'm a senior mechanical engineer working on a DIY CNC machine too. I'm building a 3-axis machine that I later can expand with one or two more axis. My focus is on mechanical rigidity, precision and a large work volume in relation to outer dimensions. My project has been resting for some time but now you have inspired me to continue. Looking forward to see more from you!
This is beautiful. Solving problems is the best way to learn, and with the internet, degrees don't matter so much. I am very inspired by projects like this. Great job!
What a fantastic job you have done. I built my own 4 axis 4 foot machine and I can appreciate how much work and thought must have gone into yours. Also I appreciated the honest "warts and all" tour of the machine. We so often have to learn by doing.
400 volts, 60 amps, three phase power.... I don't know if it's common in Germany to have access to that, but here in the US my home would have to be in an industrial park to get more than 240VAC split-phase lol. But putting my disappointment in American power infrastructure aside, this is a very cool and inspiring project! Nicely done.
I built a 4 axis machine from scratch 10 years ago, my advice is to use way covers and ballscrew covers, also route grease lines where needed for lubrication. Also think about chips, they will fly everywhere and strong coolant is worth every bit of effort. Mine uses strong mist blast, and that doesn't really cut it in many situations.
I'm in the proccess of designing a slighly smaller cnc and a video about the cast granite epoxy frame would be great. This is the best home built 5th axis cnc I've seen yet.
I’ve always had a dream to build a scaled down clone of a Hermle 5-axis, thank you for letting me see it in reality! I think with your excellent design and component decisions you will have an amazingly capable machine for years to come! Thank you for sharing anything you learned along the way (good and bad!).
I like the fact that the machine scares you, thought I was the only one... 🤣🤣 It's really an impressive build! Congratulations. Subscribed and waiting to see it cutting shiny stuff 😁
Very nice! @6:25 Many machines don't bother with leadscrew supports on the Z axis so you can probably just live without the colliding bearing block. Again, what a great job 👍👍
Thank you. That's right, the Sorotecs for example don't have one. To be honest it is quite handy tobhave this piece of steel at the end of the z axis to put a magnetic indicator stand on the otherwise aluminum part. Fixing the clearence is no big deal.
Oh my God!.. I was dreaming about such a 5 axis cnc... and you have already built that in real life... Great work!.. my best wishes and congratulations to you, friend!..
A crazy awesome build right here. Obviously the best DIY CNC I have seen on YT. And I've seen a lot. I'm facing the same issue, I want that rigid 5 axis, but I live in a flat. I can assume that your main constraint here was to be able to pass that door (after disassembly that trunion on the side and Z axis). Nice job
Thank you, yes passing through the door and being able to get it in the first floor were the main constraints. So no piece should be heavier than 100kg.
@@fabianbrock On my list of "living in a flat constraint" I've also the noise... I'm considering buiding something light with dual glass frame arround the mill. I'm sure it will damp the high frequency noise but the lower frequency noise will be transmitted by the floor ... Do you think it could be a good idea to put the all frame on some air pad or is it a dumb idea that I need to forget. All the huge machine I know are strongly bolted on the ground but if i'm gentle on the motion dynamics it could do the trick until I have enough money to buy a house.
@@UPR91 That's definitely an option. Typically the machines are set on some rubber mats to decouple them. You need to be careful with acceleration depending on your moving/stationary mass ratio. To improve this you can also add some bricks to the frame if possible just to increase the mass.
Thanks for sharing video... I can see many good design features. You should be proud of your work. I really would love to see you continue with a second and third versions,... You have talent mate..
Dear Sir, For a person with no mechanical engineering background as you said; to have built something as complex as 3 axis machine would have been quite a feat but to build a 5 axis machine instead is all the more remarkable. The mistakes which you highlighted are quite frankly really minor when one considers how far you've gone thus far. My curiosity lies in the material used to construct it ( what's painted in white???) If said machine is by your reckoning in the vicinity of 400 kg; it's pretty much the scale of an industrial tool rather than a hobby machine. I think you've excelled yourself & ought to be very proud of your achievement. It's exceedingly complex & very well built. It would be most interesting to see one of your project coming to fruition of this marvel. Very well done. Kind regards.
Thank you. The frame is made out of a mineral casting with a thin Aluminum sheet metal housing. I have a post on my Instagram where I show this in more detail. Maybe I include it in the next video.
Awesome project! Would be interesting to learn more about part sourcing (Mesa cards in Europe, industrial components, spindle, etc) and the casting process of the main body. Looking forward to the first chips! 👏
Thank you, I bought the cards already a year ago where you could just buy them. Simpler times back then. The Spindle I found on ebay, I absolutely don't have that kind of money to buy this one new. On my Instagram I have a post about the casting. I did not tok a lot of videos during the build process of the machine, only some pictures.
@@fabianbrock Thanks for the reply! Maybe some more questions (for a later video): What's your professional background (you mentioned it's not in machining/engineering) and how do you go about acquiring the required knowledge? Did you do any FEA simulations or trusted the Hermle design (square-cube law implications for scaling)? Did you consider noise/vibration dampening/decoupling in the design of the machine or its enclosure? Will you be able to run it with other people/neighbors present? How will you implement cooling/flooding?
I did a quick simulation in Fusion. Turns out the long z axis is of course the weakness, the rest dies not matter at all compared to this. But mainly I relied on the Hermle design. Another important part was not exceeding 100kg per part so I can carry it in the first floor. I can give more details on the design considerations in a future video.
@@fabianbrock weight is a huge issue if you don't live in the ground floor or have a small garage or you're renting the apartment, I've been designing my components to be max 200kg's so that 4 huge german guys can carry it upstairs or downstairs, 50kg per person seems reasonable. I hav to say though, the thin walls on your design make me really anxious. are the glass scales from china?
Looking forward to any update ^^. More in depth info is also welcome. I'm currently finishing a 3 axis cnc with the idea to make parts to convert it to 5 axis.
There were quite some questions in the comments, maybe I make a video about the design details etc. Soon I will also be able to continue the build. I wish you success for your cnc build. Is it shared somewhere public?
Sencillamente increíble. Hago mecanizados esporádicos en maquinaria manual. Pero definitivamente me apasionan los avances. Y tu presentación me permite seguir soñando con algún dia hacerlo posible. Muchas gracias desde Ecuador.
Any chance you will make a writeup or post the Build Of Material for the machine? I think there are a ton of good design points that others might be interested in building off of the design. (Like myself :) )
Impressive build! :) . I went to the videos section and noticed it's been a while. I hope you're still able to work on this and look forward to more :) .
To say no experience in engineering. What the design and knowledge just appeared one night. Thank you god. ha ha. Dude you can't just guess all this. Tried to weld and found you could so made the table. Anyway I do like it just wish I could see it milling.
Haha, didn't mean no experience, just no professional background. Of course this was not the first time tinkering around in the garage. Soon I can continue working on it and then hopefully make the first chips.
Superb work Fabian, I built a Mach 3 powered lathe ten years ago, time has moved on and now I am going to dispose of the stepper drives and fit servos. I have subscribed to your channel, my best wishes to you.
Wow, gratuliere! Diese CNC mill ist ja der Hammer. - Du bist im Video die „Bescheidenheit“ in Person, voller Respekt. Kanal abonniert, da will ich dran bleiben und danke für‘s Teilen. 🙂
That is a super cool machine! Well done! I would love to have a compact machine like that. I guess you have access to proper machines to make all of these parts?
You put glass scales on 3 axis? Does they override servo encoders in the controller ? Well done! It's absolutely incredible, the complexity of timing every axis with the rotating table/cradle. Congratulations 👍🇨🇦
The glass scales are connected to the Mesa cards and feed the position data into LinuxCNC. The servo encoders are only connected to the drives so LinuxCNC does not know anything about them. So the scales are not directly overwriting the servo encoders but the position in the controler and based on that LinuxCNC gives new commands to the servo drivers to correct the position. Hope that's somewhat understandable.
Best design I’ve ever seen diy. Do you use harmonic gear on 5th axis (C axis) ? Back lash ? What do you recommend gear that has no backlash or most little ?
Einfach nur WOW!!! Wusste bisher nicht, dass es sowas wie glass scales gibt, ist die Integration in die Steuerung kompliziert? Bin sehr gespannt auf weitere Videos von Dir!
Danke, heißt Glasmaßstab auf deutsch. Zum integrieren in die Steuerung braucht man entsprechende Encoder Eingänge. Kompliziert ist natürlich immer relativ, aber es ist durchaus machbar.
Incredible work especially considering you have no background but I can't help but imagine your neighbors in the apartment complex /really/ want to know what's making all the noise lol
this is awesome. congratulations. i think maybe you can do a better job with cable management next project. the way i do it is in 3d cad software, make simplified cad models of all the parts and assemble them, i dont use any cad models from the internet because there is too much unnecessary detail which slows down the cad software. you dont need fancy electrical softwares like e-plan to start with. but you'll have to for the fancy softwares, for more professional work, i've done it in cad, will be trying the fancy software for cable management for my next cnc build. about the y-axis : for some reason i've never been comfortable putting 2 drives for one axis, like how you've done 2 ballscrews on the y-axis. i would rather put the a single ballscrew under the bed, or have a right angle gantry one side for y and the other for x, just to eliminate synchronisation issues. are there any good machines out there that have 2 ballscrews for one axis? thank you for sharing , looking forwards to machining videos.
Thanks, yes cable management could be improved inside the electrical cabinet. Regarding the ball screws for the y axis, I get your point but for my machine it is of course not possible to put them under the bed. This would be much to far away from the rails in this build. Small portal machines have very often only one ballscrew underneath as it is way simpler and also there would be no benefit in having two. For big machines it is quite common to have two ballscews. The Hermle machines have a third approach, I'll show this in the next video. About the syncing of the drives, that should indeed work flawlessly, otherwise the gantry will twist and something could break. In my case this is taken care by the linear scales. If one of the y axes spindles is lacking behind the machine goes in an e-stop.
Any chance you might do some mini tutorial on your granite mixing/forming technique? Is it painted over afterwards? Not many good video resources on epoxy granite mixing. Yours is so clean!
Wäre mal interessant was bei so einer Maschine an Genauigkeit erreichbar ist beim Schwenken, kannst du ja mal testen mit der Kugel und dem Taster Tolles Projekt👍👍
Danke, Flutkühlung ist natürlich so ne Sache auf Laminat Boden aber mal schauen wo die Reise hin geht. Umhausung kommt erst mal nicht viel. Die Maschine ist ja selbst quasi schon eine. Eine Tür kommt noch vorne und hinten dran.
@@fabianbrock so in der art meinte ich das mit der umhausung. joa, bei flut müsste halt wirklich alles dicht sein. wie hast du denn die ganzen teile, die genau sein müssen, angefertigt?
As mentioned this is a compromise to get the weight down so it can be used in the flat. The machine is not yet finished but as soon as I do the first cuts I'll post a video of it.
If you want better damping and long life of the machine then go with as much hydrostatic as you can ( like hydrostatic ways for the axis. Hydrostatic lead screws and hydrostatic bearing for the turning axis) since hydrostatic is both damping but also non contact. And also doesn't have stick slip effect unlike ball screws and linear rails do Also something I would add ( since it's quite easy) is high pressure air around the spindle/tool to blow away chips we'll cutting ( good for deep slot milling so the chips get blown away instead of double cutting them) And a thin water/dust proof ring light around the spindle nose ( sometimes the spindle it self blocks the light making it hard to see what's happening)
These hydrostatic rails might be outside my budget. For now I will use what I have. Air pressure with a little bit of cooling (minimum quantity lubricatin MQL) is already planned. Lightning will also be needed.
@@fabianbrock then you can fram some cheap camera ringlight put it around the spindle nose and cover it in transparent silicone so chips and coolant cant get in there and short it out
Interesting idea, let's see how it works with the current configuration, maybe I'll adapt one later on. Of course this also depends on the work piece setup if a counterweight is beneficial.
Awesome machine! Does it have some sort of built in way for spindle tramming? like set screws or something? Or maybe this can be compensated by 4th and 5th axes? how does this work? thank you!
You can't really compensate Spindle tram with the 4th and 5th axes. The Spindle needs to be aligned to the Z axes so the rotary once don't help here. However, they make the table alignment with the Y axis a lot easier. For now I have this standard aluminum casting import spindle mount and tramming needs to done with an indicator and a soft hammer.
@@fabianbrock I'm curious what kind of positional accuracy and repeatability you are able to achieve. I hadn't thought of using glass DRO scales in my design.

Hope that's somewhat understandable.
@@fabianbrock brillant! Very smart way to precision machining! Thanks for your answer!
sehr cooles project, das macht neugierig auf die ersten Späne ;-)
Ja das wird hoffentlich endlich mal was.
Best design I’ve ever seen diy.
Do you use harmonic gear on 5th axis (C axis) ?
Back lash ?
What do you recommend gear that has no backlash or most little ?
Thank you, yes on the 4th and the 5th axis I use Harmonic drives. These are the FHA-32B and FHA-25B respectively.
Einfach nur WOW!!!
Wusste bisher nicht, dass es sowas wie glass scales gibt, ist die Integration in die Steuerung kompliziert? Bin sehr gespannt auf weitere Videos von Dir!
Danke, heißt Glasmaßstab auf deutsch. Zum integrieren in die Steuerung braucht man entsprechende Encoder Eingänge. Kompliziert ist natürlich immer relativ, aber es ist durchaus machbar.
Glasmaßstäbe sind an so ziemlich jeder professionellen Fräse verbaut
@@johanness6545 ansonsten wärs keine Professionelle :P
would be also interesting to see how you made the 5 Axis control via LinuxCNC - I mean the kinematic part
There seems to be quite some interest in that topic. I will show this in a future video.
Fantastic job!
Thank you
Very nice. (And good choice of controller ;-)
Thank you
Nice machine friend
Thank you
Dude has an accent and a 99.9% 5 axis.
Also Dude: I'm not a professional engineer...
Schickes Spielzeug, gerne mehr dazu
LG
Dankeschön
Nice little monster! Can't wait to see it bite on something! ;-)
Thank you, I am also looking forward to the first chips.
Super Arbeit. Vielen dank für das Video.
Dankeschön
Incredible work especially considering you have no background but I can't help but imagine your neighbors in the apartment complex /really/ want to know what's making all the noise lol
Thanks, there is only one other apartment below and I told them 😊
Looking forward to the machining videos! Looks epic.
Thank you, I am also looking forward to machining 😀
this is awesome. congratulations. i think maybe you can do a better job with cable management next project.
the way i do it is in 3d cad software, make simplified cad models of all the parts and assemble them, i dont use any cad models from the internet because there is too much unnecessary detail which slows down the cad software. you dont need fancy electrical softwares like e-plan to start with. but you'll have to for the fancy softwares, for more professional work, i've done it in cad, will be trying the fancy software for cable management for my next cnc build.
about the y-axis : for some reason i've never been comfortable putting 2 drives for one axis, like how you've done 2 ballscrews on the y-axis. i would rather put the a single ballscrew under the bed, or have a right angle gantry one side for y and the other for x, just to eliminate synchronisation issues. are there any good machines out there that have 2 ballscrews for one axis?
thank you for sharing , looking forwards to machining videos.
Thanks, yes cable management could be improved inside the electrical cabinet.
Regarding the ball screws for the y axis, I get your point but for my machine it is of course not possible to put them under the bed. This would be much to far away from the rails in this build. Small portal machines have very often only one ballscrew underneath as it is way simpler and also there would be no benefit in having two. For big machines it is quite common to have two ballscews. The Hermle machines have a third approach, I'll show this in the next video.
About the syncing of the drives, that should indeed work flawlessly, otherwise the gantry will twist and something could break. In my case this is taken care by the linear scales. If one of the y axes spindles is lacking behind the machine goes in an e-stop.
What is your proffesional background? Even though you might not be an engineer officially, you certainly display similar skills/knowledge. Well done!
I have studied physics and I am currently working for a big software company.
Any chance you might do some mini tutorial on your granite mixing/forming technique? Is it painted over afterwards?
Not many good video resources on epoxy granite mixing. Yours is so clean!
It is so clean because on the outside there is still the aluminum frame. I'll discuss it in my next video.
This is amazing work. Thanks for sharing.
Thank you.
Just a hobby ! Very good!
Thank you
Beautiful machine! 👍
Thank you, and I like the Gaston comics too.
Wäre mal interessant was bei so einer Maschine an Genauigkeit erreichbar ist beim Schwenken, kannst du ja mal testen mit der Kugel und dem Taster
Tolles Projekt👍👍
Danke, werde ich machen und dann berichten.
sweet machine it will be interesting to see what it can do
Thanks
brutal. ich bin so unbeschreiblich neidisch, wahnsinns projekt. baust du noch ne umhausung drum? wirds ne flutkühlung geben?
Danke, Flutkühlung ist natürlich so ne Sache auf Laminat Boden aber mal schauen wo die Reise hin geht. Umhausung kommt erst mal nicht viel. Die Maschine ist ja selbst quasi schon eine. Eine Tür kommt noch vorne und hinten dran.
@@fabianbrock so in der art meinte ich das mit der umhausung. joa, bei flut müsste halt wirklich alles dicht sein. wie hast du denn die ganzen teile, die genau sein müssen, angefertigt?
@@Windows350 Ich habe so eine Importfräse FM45 von SWM bei meinen Eltern in der Garage stehen. Mit der habe ich alles überfräst.
I like this design. It's something I thought about to build.
But it seems to be very weak and not rigid enough.
Can you show how it mills?
As mentioned this is a compromise to get the weight down so it can be used in the flat. The machine is not yet finished but as soon as I do the first cuts I'll post a video of it.
Awesome!
Thank you.
Great build! Thanks for sharing
Thank you
Very nice
Thank you
Well done. Very cool
Thank you
If you want better damping and long life of the machine then go with as much hydrostatic as you can ( like hydrostatic ways for the axis. Hydrostatic lead screws and hydrostatic bearing for the turning axis) since hydrostatic is both damping but also non contact. And also doesn't have stick slip effect unlike ball screws and linear rails do
Also something I would add ( since it's quite easy) is high pressure air around the spindle/tool to blow away chips we'll cutting ( good for deep slot milling so the chips get blown away instead of double cutting them)
And a thin water/dust proof ring light around the spindle nose ( sometimes the spindle it self blocks the light making it hard to see what's happening)
These hydrostatic rails might be outside my budget. For now I will use what I have. Air pressure with a little bit of cooling (minimum quantity lubricatin MQL) is already planned. Lightning will also be needed.
@@fabianbrock then you can fram some cheap camera ringlight put it around the spindle nose and cover it in transparent silicone so chips and coolant cant get in there and short it out
Can't wait to see this make chips
Me too
I would put a counterweight on A axis for balance
Interesting idea, let's see how it works with the current configuration, maybe I'll adapt one later on. Of course this also depends on the work piece setup if a counterweight is beneficial.
Awesome machine! Does it have some sort of built in way for spindle tramming? like set screws or something? Or maybe this can be compensated by 4th and 5th axes? how does this work? thank you!
You can't really compensate Spindle tram with the 4th and 5th axes. The Spindle needs to be aligned to the Z axes so the rotary once don't help here. However, they make the table alignment with the Y axis a lot easier. For now I have this standard aluminum casting import spindle mount and tramming needs to done with an indicator and a soft hammer.
Beeindruckend. Quasi eine Hermle C12U 👍👍
Danke. Genau, Hermle war hier das Vorbild. Nur ein wenig kleiner.
best idea broo
Thanks
Beautiful machine!!!!
Thank you
Impressive.
Thank you
@@fabianbrock I'm curious what kind of positional accuracy and repeatability you are able to achieve. I hadn't thought of using glass DRO scales in my design.
@@warrenmusselman9173 I'll test this in future, the mill is not yet finished enough for this test.
