Ziet er indruk wekkend uit Stef. Ik ben zelf aan het orienteren om een Mikron wf21c om te bouwen met Eding cnc en servo motoren .de motoren die je nu gebruikt zijn ze goed? Is het makkelijk in te regelen?
This shouldn't even be called home made. I mean, I get that it's literally made at home, but this is more like very advanced in house prototype machine design and fabrication. This is such an amazing build, and you've really raised the bar on just how amazing a "DIY"/"Homemade" project can be. I hope your machine gets lots of jobs!
One of the best builds I've seen. Too many people waste money buying thicker aluminum plates, with no understanding of second moment of area (or the fact that steel is 3x stiffer to begin with). Nice work.
Most professional and thoroughly thought out design of any diy cnc machines I have seen, and better than some of the factory made far east machines out there! Now just add tool magazine and covering and its done! Fantastic work!
Home made 😂😂😂 its only the beginning of cnc machine assembly.after this we need guard, coolant syste, door, panel, telescopic cover,lubrication unit,frl unit etc
Try building a real machine with hardened and ground box ways. Linear guide ways are cheap and weak. Filling in with epoxy won't help to make it accurate If the ball screws aren't quality and the backlash varies. Use real meanite iron. What good is another cheap Chinese machine ?
@@jimsperlakis5634 please send link to your "Kern" that you built. Many new machines are using linear rails ... Many more things I might add but I'll give you a chance to take a breath 😜
This is quite impressive. I would love to watch videos on making the base and column molds as well as the actual making of the base and column. It’s nice watching the mold being pulled away from the hardened epoxy to reveal a perfect casting.
I’m very impressed and humbled by what you’ve done, I bought a used Fadal machine and it needed to be disassembled down to the casting, cleaned and rebuilt on the way back together, I’m always complaining because I can’t get my hands on a manual, and you don’t need a manual at all ! My hat is off to you Stef
Very nicely done!! Would be interested to know the squareness, straightness, flatness and repeatability of the machine. Very impressive accomplishment Stef, thanks for sharing... Enjoy your machine!
Stef. You’ve got to be quite proud of that build. Kudos to you. I’m looking into the utilization of epoxy-granite to fortify the base of my machine. You’ve given me some great ideas (and inspiration as well).
The exposed table stepper motor worm drive will fill up with shavings in no time and destroy the drive. You need a complete box to cover the drive system.
Wow great job! I'm jealous of your skill in designing this. One thing to be aware of is if you test that vertical servo brake while the load is moving, the brake surface will glaze and make it much less effective. They are designed to be static holding brakes only.
Very well done!!! A little advice about the Spindle if you allow me, always warm up step by step (10%-30%-50%-70%-90%) 10 minutes each step from a completely cold spindle or your bearings will last no time... start the spindle at 6000 rpm is not recommended. Other than that Amazing Job!!!
One of the most sick homebrew CNC's I have ever seen. Same thing could have worked for 3x bigger table easy and still be an overkill. That is 3x longer and 3x wider bed so 9x bigger table.
And I though, my little mill was cool... This has to be the single most impressive DIY build I have ever seen anywhere! Just out of curiosity: what did it cost?
@Rotten Brainz there's reasons to mill metal. Personally I can't stand using the modeling software to make the files to do it though. Which is why I don't use my CNC machine. Well, I'll use it for 2.5D jobs. Full 3D is not for me.
Amazing work. I know how much energy it takes to pull this off. Awesome. With the power on that machine get your enclosure up ASAP your chips will fly off like shrapnel lol
That's seriously one of the best diy machines I've seen. Those 30 dislikes have to be from overly jealous people. I'll now go to play with my MPCNC and leave you big boys alone :D
Thanks for showing this impressive work Stef! Someday I hope to do something similar, though I'll probably go a bit smaller. I look forward to seeing how the tool changer works out. It's awesome to see someone building professional quality in such a small infrastructure, it really shows what's possible for those willing to put in thought, time, and not a little bit of money.
This is a very sophisticated build and a credit to you. It may be a little over engineered but there is usually some payback which should be in accuracy and repeatability. I suspect many who wish to see it made open source simply do not appreciate the time and resources (mostly cash) that go into something like this. Anyone who is actually capable of emulating this project can work out how to go about it and it certainly this would be way beyond most first timers.
When I owned my machine shop the head on my CNC mill was 3200 LB's. or 1451.496 KG's. and even with the break a power outage happened and the Cutter dug into a mold cavity about .010 IN. or .254mm. during a finish cut and that was with steel counter weights.
Great looking machine, If spindle bearings and motors are quite, whole machine operation is quite, accurate and reliable you have a winner. It sounds a little noisy, Solve those issues and I think you got a very good machine.
There are ''plugs'' to put into the screwholes for the linearguides where the linearbearings slide. Otherwise the holes will get clogged up with grease and dirt.
nice mill! Are you gonna protect the ball screws with some sort of telescopic covers? Maybe adding an enclosure to keep the coolant from splashing all around your shop would be good to keep the area clean.
Hi Stef, that's an awesome CNC build! I am thinking about building a CNC as well. A question that is concerning me is how to make sure all axis are perfectly square / aligned. Could you make a video to explain how you did it? I believe this will be highly relevant for many people
When using epoxy granite or UHPC you always need to sink a metal (aluminium, or preferrably steel) frame into it. Not only will the metal frame help to reinforce everything and make it even stronger, but more importantly the steel frame will contain all the mounting and attachment points to bolt things to, for example the column of a mill to the base, or the linear rails. Unfortunately the frame will always get slightly bent and deformed as the concrete or resin hardens, and so you will have to correct that afterwards and before assembling everything. The best way to go about correcting it is by first milling it to do the rough correcting and then hand scraping to do the fine correcting. Once you've done that you will have perfectly flat mounting surfaces, ready for assembly. You will need various tools to do the hand scraping and to accurately allign and mount all the parts and components, things like a test indicator, precision angle plate, precision level, camelback, etc.
Exceptional on many levels and nicely sized for the limited available space. I suspect that there will be more spindle engineering and development in the future. It will be fun to watch you explorer and innovate solutions. Sadly, added rigidity, precision and speed translates into $$$$$$. But in the meantime, button the thing up and sling some chips. 😁
AMAZING build. Seriously. That looks fantastic. If I can make one suggestion based on my own personal experience/opinion: either put the keyboard on a hinge to be able to sit horizontally. Or - and this is likely what I'd do personally - get a wireless keyboard remote (they're popular with Raspberry Pis) and make a little cabinet where your keyboard currently is where it can be stored and not get dirty. The reason I suggest this is that I really dislike typing on a keyboard vertically like that, plus the remote has a trackpad and backlit keys. And they're wireless with a pricetag of $10-20. So when it inevitably gets broken as a result of being in a shop, it's easy to replace while still being very convenient. I also hate typing on a touchscreen, but I've found most of what I find uncomfortable is the vertical orientation. It's like trying to use a TIG pedal standing IMO. Though if you're perfectly comfortable with it, it's a moot point. And again - GREAT job. I think I'll try my hand at something similar
I think what you've done is really nice. This was my approach for a base also. I'm curius to know how it handles vibration as a weldment. I believe the base would do quite well for most machining even without being filled. I think the spindle motor is powerful enought to rattle even a cast iron base....so I don't think you'll be running at full speed often. Also, the spindle sounded loud to me...like some bearing noise but maybe just belt noise. Hard to tell on youtube tho. Cheers and great build.
Wow, that's really well done. I wish I had the time to do this, I would love to build a small machine to use at our shop. One this I just don't get though. Every build like this I see people using tiny ball screws and lineal guides. If your going through all the trouble why don't you get some guides and ball screws meant for a full size VMC. That along with a good spindle and granite epoxy base and you'd have an amazingly ridged and accurate machine for doing small parts
I can't find the articles where I saw this, but I read in at least a couple of places that people tend to get rails that are far larger than necessary because they feel like the thinner rails look too small when in fact even the 15 or 20mm rails can still handle a surprising amount of loading (talking about d.i.y. size of machines) based on their specs. So, I guess the bottom line is that you have do the calculations for your rail and application, and probably the rail will be smaller than what you might expect. Here are a couple of nice articles on linear rail selection considerations: www.machinedesign.com/automation-iiot/article/21828134/common-errors-in-linear-guide-way-selection, th-cam.com/video/EssAbsCut_s/w-d-xo.html, th-cam.com/video/wsS7ifd-Gpo/w-d-xo.html, and a nice one on how alignment is critical for rail life: www.thomsonlinear.com/en/support/20150125-na. This discussion www.cnczone.com/forums/mechanical-calculations-engineering-design/8083-cad.html, has a comment, "When I was designing my machine I brought in the THK rep and he said that everyone over-estimates their needs by some considerable margin." I have no idea if the rails in this video are over-engineered, if so it would be interesting to know by what factor given expected forces for all his use cases.
Nice Machine. On mine I counterbalance the Z with an air cylinder except I use a regulator, So I am not using air as a "spring"" to provide a constant force for the entire travel, also lets one adjust the counter force depending on attachments, although that is just a bonus.
Haha amazing ,been thinking of building a mill and while i was on a walk today I saw a cement beam lying on the ground ,instantly thought I wonder could u use epoxy cement to make a mill ofc I was nowhere near the first to think it !
Nice machine good to see you share this project taking on such a task is quite the challenge. Lance & Patrick to your subscribers and viewers. Wow hydraulic cylinder counter weight instead of the lead ballast weights form the past CNC machines we remember them as how neat is this, neat to these two guys. We use a BT 30 spindle here for our second operation US made bench top horizontal milling head we can relate. ??? Are your bearings angular contact or deep groove, if so what class wanting to learn here if you do not mind. The electronics look really nice.
I wonder if it's possible to regrease the spindle with a higher performance grease to get more RPM out of it. And maybe add a water jacket around it to cool it?
The majority of the industrial machining centers I've seen use ball screws and rotary encoders on the servo's, with no linear scales. It works well for precision to at least .0001 in
@@Nidkidful at 7:36 he mentions at least one of the ball screws is C7, so kind of not that accurate although probably some of the errors can be mapped in software and compensated for. C7 is apparently +- 50 microns (roughly .002") per 300mm (tech.thk.com/en/products/pdf/en_a15_011.pdf) but maybe the precision could still be much better, like the .0001" you mention. Not sure.
very nice. do you have a background in automation? i like the idea of the air spring on the z axis, less inertia and adjustable if you ever had a heavy tool.
Awesome machine! Subbed. How do you plan to protect the linear rails and ballscrews from chips and coolant? And do you plan on making a automatic tool changer?
Where do you get the epoxy granite? Can't you just use some high density concrete with small aggregate and then seal it? Maybe add some fibers to give additional strength to the concrete?
Это отлично, друг! Но что ты будешь делать со стружкой? Защита компонентов станка и окружающего пространства от стружки поначалу кажется второстепенной задачей, но это должно быть спроектировано с самого начала, иначе потом могут быть сложности с реализацией защиты.
Stef, I've been watching your build on this project, it occurred to me that the effort and cost of the machine would it not have been just as cost effective to go buy a similar machine, mind you nothing can compensate for the experience of the build, nice job 👴🏻
Yeah, he could have had something considerably better for the €15.000-16.000 he apparently spent on it. I regularly browse an auction site for industrial equipment such as metalworking machinery, and its not uncommon to find professional 5 axis CNC's for €10.000-12.000, or 3 axis CNC mills for a few thousand Euro's. In fact he could have had both a professional 1000 mm between centers lathe and a 3 axis CNC mill for a third or even a fourth of what he spent.
Inspiring work Stef. Extremely well designed and built and a comprehensive video presentation. Well done. Why would TH-cam take down your previous video? Loved your firewood stack outside the door:-)
Tnx man really appreciate these comments! TH-cam removed it because i used a word that the TH-cam computer didn't like so they took it down for 24 hours so i decided to make a new one. And i must say this new version was better and longer then the old one. :)
A beautiful build! Amazing. Still, I see @0:41 you're having trouble screwing in the y-axis linear bearings ;) Damn fabrications and castings.. as a machinist as I had to deal with this all the time.
Hey thnx! You mean i didn't screw down the yaxis linear bearing guides. During the making of this video noting was screwed down 100% also nothing was aligned for the full 100%.

No not really automation, im an electrician. This whole machine is build as a hobby that went a little out of hand😆
This is amazing, one hell of a spindel servo!!
Superb Build..hats off to your skill...Kudos to you
Awesome machine! Subbed.
How do you plan to protect the linear rails and ballscrews from chips and coolant? And do you plan on making a automatic tool changer?
I wonder if you could just make an enclosure for the work table. I think it would need sliding panels to move with the machine.
Slide way covers...
Very nice! I look forward to see what you do flood coolant etc!
Where do you get the epoxy granite? Can't you just use some high density concrete with small aggregate and then seal it? Maybe add some fibers to give additional strength to the concrete?
Hi Stef van Itterzon, I have been following. I found that some of the previous videos of making epoxy resin are gone. Where else can you see it
Epic build! I can't wait to see it break some chips.
Это отлично, друг! Но что ты будешь делать со стружкой? Защита компонентов станка и окружающего пространства от стружки поначалу кажется второстепенной задачей, но это должно быть спроектировано с самого начала, иначе потом могут быть сложности с реализацией защиты.
Brilliant piece of machinery. Top work.
Stef, I've been watching your build on this project, it occurred to me that the effort and cost of the machine would it not have been just as cost effective to go buy a similar machine, mind you nothing can compensate for the experience of the build, nice job 👴🏻
Yeah, he could have had something considerably better for the €15.000-16.000 he apparently spent on it. I regularly browse an auction site for industrial equipment such as metalworking machinery, and its not uncommon to find professional 5 axis CNC's for €10.000-12.000, or 3 axis CNC mills for a few thousand Euro's. In fact he could have had both a professional 1000 mm between centers lathe and a 3 axis CNC mill for a third or even a fourth of what he spent.
Fantastic Work, My hats off to you. Well Done. : )
Tnx!
It looks sweet but that aluminum x axis mount is going to have stiffness and resonance issues
Inspiring work Stef. Extremely well designed and built and a comprehensive video presentation. Well done. Why would TH-cam take down your previous video? Loved your firewood stack outside the door:-)
Tnx man really appreciate these comments! TH-cam removed it because i used a word that the TH-cam computer didn't like so they took it down for 24 hours so i decided to make a new one. And i must say this new version was better and longer then the old one. :)
A beautiful build! Amazing. Still, I see @0:41 you're having trouble screwing in the y-axis linear bearings ;) Damn fabrications and castings.. as a machinist as I had to deal with this all the time.
Hey thnx! You mean i didn't screw down the yaxis linear bearing guides. During the making of this video noting was screwed down 100% also nothing was aligned for the full 100%.
Awesome build Buddy! Thanks so much for sharing! You are doing a great job!!! 👍
Tnx
