The amount of aluminum extrusion that Ivan goes through is what keeps that industry booming. Keep up the hard work Ivan! This is one of my favorite channels
@@zakquddoos4641 A flexarm would only really be useful for drilling and tapping the faces of the extrusion, not the length of the extrusion; though a flexarm isn't that useful in making the process more efficient. A better solution for the lengths would be a horizontal drill/tap setup, where the extrusion is butted against and endstop and a horizontal stop, while using the table for a vertical stop, for placement, with the spindle on a guide and spring for when drilling and tapping; all you'd need to do is rotate the extrusion to dill and tap the next hole, as each predetermined stop will accurately locate the spindle for the next operation. For the repeated drilling along the face perpendicular to the length, a setup on the drill press can be used, all it needs is a pin for the endstop and a second pin that'll also locate the previously drilled hole to setup for the next hole being drilled, as this is a pretty basic operation. The only use a flexarm would actually provide is a preventative for repetitive strain injury from drilling and tapping each hole with a hand drill.
Nice builds but there are many problems that I see with your builds FYI I have been building cnc mills for the past 10 years . 1 it you fill the aluminum extension with epoxy granite that will help with the vibration that will increase The CNC performance . 2 add a support beam at the front of the xy carriage that will make the Bed more flat . 3 Mill the connecting surfaces flat ( where the Linear rail Is mounted ) 4 add steel plates in the z axis of the spindles. 5 buy a metal spindles not a wood spindle like you are using the Will improve the tolerance and will last longer.
Can we all just take a moment to appreciate the tolerances to which Ivan needs to keep for these projects and that he does most of it with a hand drill. Awesome :)
Nice CNC machine build. Try a slightly smaller ripper bit for rough cuts, then the right size end mill for the finishing pass; that's what I use now and it eats through aluminium even with only a 150W spindle motor and finishes nicely without changing the G-Code. Also, you may want to look at getting a septic tank aeration pump instead of a compressor to blow the chips away, I tried this and it works really well, plus is only just above 30dB and will run continuously for years.
This is awesome! However, I will say, as someone who owns an actual 3 axis CNC knee mill, you really should have put the Z axis movent in the knee....while yes, you can move the knee up and down for larger parts, but having such a limited z travel (as I do with an automated quill), it's extremely limiting with respect to cutter length and retract/clearance heights...very annoying....the next thing I do to mine is going to be put a ball screw in the knee, add two gas struts to offset the weight, and cut a hole in the casting to run a belt drive go the top of the screw....
You can save a lot of time if you first make roughing passes with a flat end mill and then move to a ball end mill (with a much faster feed speed). Also end mills are much more efficient at working with their sides, avoid milling downwards at all costs. The surface finishes will be much better, you will be able to use faster feeds, you will significantly reduce the chances of the end mill clogging up (and breaking) plus the tool life will be longer. You made yourself quiet a tool, really interested to see what you will make with it, good luck!
It this case I don't think it makes much difference since his frame is not rigid enough to handle the cutting capacity of a typical end mill. He needs to keep his cut depths and feed speeds low to get any accuracy. The aluminium is flexible.
A recommendation for bolting down linear rails: they are likely to be much straighter than what you're bolting them to, so rigidly bolting the 2 parts together will warp both parts. Use a stack of Belville washers on each bolt (6 will do, alternating them to face opposite directions) and tighten the bolts up only to the point when the washers are partially compressed; you'll need to use thread lock on the bolts to ensure they don't loosen, but you rails will remain absolutely straight.
I would have printed a hollow frame to designed to pour concrete over steel rebar, and pre stress bolts. Then thick steel ways, motors, table bolted to the frame. Maybe electronics boxes printed.
When machining metals rigidity is not enough. The machine needs mass. This is why machine equipment are so heavy and bulky. The quality of the cut is night and day. Great vids and content :)
Such an awesome build! You should try to avoid slotting with your endmills as much as possible, it's horrible for surface finish and chip evacuation/tool life. Also on the hemispheres you could try running a roughing pass with a sharp corner endmill, or one with a small radius. Then come in for a finishing pass with the ball nose.
Very late, but don’t you know it’s a very bad idea to use a coolant mister in a non enclosed machine, coolant is already caustic to your skin. So why would you want to breathe that in
I would love to see this mounted on a proper base (maybe cast concrete? maybe even with attachable dampers?) just to see if it effects part quality or not!
Hey there! Two suggestions for lubricants that won't catch fire: Cool Tool II is got for squirting right out of the bottle or for applying with a brush. It's good for tapping too. Plan B is a soluble oil (there are dozens; I like the stuff sold by Mobil) you can mix with water and spray with a bottle or with a spray mist unit.
Ivan your an absolute weapon!! I love your builds. As a CNC machinist myself I really appreciate what you do and live your antics. You keep saying your machining skills need work. May I suggest the following: Instead of IPA use a petroleum jelly or kerosene as a cutting lubricant for Aluminium (it's what we use in industry) When setting your toolpaths try to do it in such a way that you maintain a constant chip load as this will give you good performance from your cutting tools. If the material is fraying like it is, it's because the speed is to high and it is cold welding the chips back onto your workpiece as the tool is bringing the chips back around. Imagine metal cutting as more of a sheering than a cutting action, like scraping a knife along a block of butter rather than slicing straight down through it. You are essentially trying to force the material apart, the softer the metal the gummier and less likely to separate it is, excluding self lubricating materials such as bronzes and brasses. Have a look at the Vm data on your cutters and they will have operating ranges for speeds and feeds, going below is just as bad as going above. Look at your tool and see what it is telling you. Chipping means too high a chip load, a built up edge on your tool means to fast or the wrong coolant/lubricant, carbide tooling when it's sharp has a dull edge feel, when it feels sharp it's dull. Generally when cutting dry I reduce the speeds and feeds by about 50% to prevent problems. For demo prices and trial cuts use a free cutting brass as it almost never clogs the tooling. Ok hope this helps a little. Keep up the outstanding work!!
You should really consider a very good filter for your electronics fan. That metal dust could brick a very expensive controller. Also, Rotary table coming next? If you have a CNC machine may as well make it 4 axis
Can we all just take a moment to appreciate the SOUND of those Nema23's as they spool-up into that whirring symphony of CNC magic... Mmmmmm... SO good!
I am shocked at how cool and how much slop there will be in this machine.. but nice. Also some advice, well i didn't see if you implemented them, but thrust bearings for your steppers, they cannot handle that much axial load, so adding thrust bearings will be a large advantage when milling.
I have watched uncountable projects that involved designing and making tools. This one is my all time favorite. And of course the red PLA is the icing on the cake.
Hi. This is an amazing project! Maybe you already solved it, but on the minute 18:35 when the Z axis stops, is can be seen as the screw support deflects a bit. Could be worth checking.
The performance on aluminium and thin wall steel is far better than I expected at the beginning of the video. All that must happen now is to fine tune all the axis (90 deg to each other) and maybe some gussets to stiffen where needed and you will be good to go. Congratulations ! ! Next? Maybe a 5 axis mill ? Or take over the world ? Or both...
Do you have some kind of scale to read the angle that the tool is at? This might be useful for getting exactly perpendicular to the platform and repeatability. Looks intriguing!
Very much worth checking the grounding on Chinese made spindles; even the popular round body spindles (that are often sold with a VFD) have 4 pins (U,V,W and Earth), but in my experience the 4th pin is usually connected to nothing - i.e. even if you ran a U,V,W + Earth cable to the spindle, the metal spindle body will not be grounded.
Long enough to make metal replacements? Start with aluminum and proceed to steel if needed. Should take care of normal wear and tear and stiffen it up slightly more as there are a few parts that may flex a little like the 3D printed end pieces for the frame stabilization legs. I was a bit surprised when he used those between the upright and the legs.
Nice work btw. You’ve shown people they can build on a budget to get started in CNC. FYI you could also consider buying precut ATP-5 plate for components. It comes precision machined and adds weight over extrusion. Makes great printer beds, machine base, columns, etc. You would see the benefit mixing material types quickly and so would your viewers. As I mentioned earlier 3d printing lost wax into casting of parts. You have the tools and knowledge to evolve. I bet if you went this route it would be a matter of time before you could compile all your videos into an evolution of DIY to industrial machinery. This is what guys like myself have done to get where I am. Ive built my own industrial machine little over a year ago and it’s sitting in storage waiting to be wired up soon as I find the space i can use it. You’ve got the space so Go for it.
@@polviaortega3709 i mean makes sense. If you go with aluminum profiles you can not expect crazy precision. The frame is not death flat anyway. So router application fit better. I made a router while back but since I machine mostly aluminium and steel, I have converted a bf20L to CNC, with tons of features. Still hobby machine but much better for my application. A router is really nice for big not tall parts, preferably wood and plastic. If you want one efficient in metal then you need to invest on the frame. Machine aluminium and epoxy granite if possible. Linear rails ecc...
@@Ale_Lab Thats what I meant. Routers are cheap and easy to manufacture but what really gets the job done, specially in metalworking, is the VMC. I would love to se more DIY and hobby VMCs instead of routers.
Ivan, fantastic video as always. As a machinist and engineer, as soon as I saw the spark on the aluminum I thought 'Oh something shorted....' I can't believe that spindle isn't grounded though. Not sure I would be comfortable using that in the long run but your addition of a grounding wire is certainly a good improvement!
I appreciate your true and total transparency of your design process. Any other UA-camr would use the power of editing to completely eliminate any errors made along the journey. Especially with the electrical issue, it would have been so easy to not show the grounding and wiring issue, and cut out the bad test cuts and said "hey look, first cut cane out perfect!" Bravo, for staying grounded in reality.
If you plan on doing a lot of cutting, build an enclosure and use flood coolant instead of just spray. It will give you a much nicer surface and allow you to speed up the process. Not to mention that flooding will wash away the metal chips so they are all in one place for easy clean-up! Also the bottom right spindle bolt is not tight, you can see the washer spin freely there in the video.
This really cool. It would be even cooler if you used this machine to machine more ridged parts to replace the original ones. I think this would end up being a great video series and the results could be a stronger machine with higher tolerance capabilities. “The machine that made itself better”. Cheers for the video again
muy chula la CNC!!! ¿Qué modelo de gafas de protección usas sobre el min 16:33 ? no encuentro unas gafas de seguridad que no me molesten con las gafas de ver Saludos
Very very cool Ivan might I recommend a piece of literature to help with your machining. The machinists handbooks has so much great information in there it is prefect for most of what you are going to need. everything from calculating feeds and speeds to calculating gear geometry and material sciences truly a required bit of kit for anyone who wants to machine
He quedado sorprendido de este proyecto, y lo voy a hacer pero tengo unas dudas: 1.- En la compra de los planos viene incuidas las parte que hay que imprimir en la impresora 3D? 2.- Que tipo de impresora es necesario, dimensiones? Tipo de filamento? 3.- Alguna recomendacion que me hagas para iniciar este projecto ( especificaciones de motores, router, etc...)? Muchas gracias y felicidades por el canal
Could you add a thermal sensor near the bit that if it hits X temperature, it'll squirt 3-6 pumps of IPA on the bit? Maybe give it limitations so it doesn't just constantly do it though.
I would like to see the cut quality in aluminum using the single flute, nice slow feed cutting strait lines(the wall finish). It doesn't sound like there is a ton of vibration which seems impossible given the wrong linear rails, hollow aluminum and plastic holding it all together. I'd say I'm most impressed by the spindle but not the grounding of said spindle.
cast the whole bottom into concrete so it has some mass. Use roughing endmills and then a finishing one especially if you are going to use a ball end mill and consider encoders so it know when it skips steps.
Wow! Crazy project! I need a CNC machine and I was thinking about making one myself... I'm not sure I should do it. This is more complex and time consuming than I thought. Anyway, congratulations for another incredible build. 😍
As cool of a project as this is you could buy an actual milling machine for the cost of the profiles! I have been through several iterations of milling machines in the past few years and in the long run I just ended up buying an industrial milling machine and have finally found my machining happy place. I had a few table top mills that I converted that did nice work but ultimately I wanted to make many big parts and went all in. The table top mill conversion is an excellent route for someone looking to get somewhat serious about making aluminum parts. That being said, I have scratch built machines and understand they joy of making the machine itself. This is kind of a tedious route to take however.
Ivan, I just need to say thank you again for all your awesome videos. I really love how you improved over the past years. You truely mastered your craftsmanship AND video editing. Love your content so much. Everything is just perfect. Thanks!
Every time I see him build stuff with a fresh stack of that extruded metal. I think he is some kind of maker king, living a lavish life a wood using peasant like me could never afford.
@@ivanmirandawastaken oic, kinda figured it was. The reason i asked was if it was R8 like a Bridgeport mill you could chuck the end mill higher and not be extended like that and have much less chatter. But no matter that is a amazing little mill that i would have said not possible not to long ago.
That was my first thought when I saw him tilt the head. "Just add a ball screw and a motor and you get a fourth axis". But then I thought about it. Can the CAD software make use of that functionality? When reading up on CNC mills the fourth axis is always referred to as the A-axis, and is defined as having the workpiece rotating around the X-axis. I seems it would take a lot of tinkering to make the controller and cad software understand what to do with a fourth axis that tilts the head and has quite limited movement.
Amazing! I'm interested to see if the 3D parts hold up after a few weeks of machining. I would also recommend an MQL system. I installed one on one of my small CNC machines and it completely transforms it. And getting some single flute cutters may be a good idea as they seem to work better with machines that aren't as ridged and that have slow cutting speeds.
why did you make it only cnc controlled? isnt the whole purpose of a mill like that to be able to hand crank the axis so you can cut a piece without having to plan it in software before?
What an incredible video again. A beautiful machine. Have you considered adding some sort of vacuum next to the bit to recover dust and scraps....help keep everything clean?
Nice JOB. You make it look so easy... =D Glad you got into other materials besides plastics. Thx for sharing all this on youtube. I spent weeks shimming up my lathe headstock to get it to run true... Anyways, the editing is amazing. Keep up the good work.

The amount of aluminum extrusion that Ivan goes through is what keeps that industry booming. Keep up the hard work Ivan! This is one of my favorite channels
Ivan just a thought. The number of profiles that you drill and tap, sounds like a new machine is required to automate such procedures👍

¿Qué modelo de gafas de protección usas sobre el min 16:33 ? no encuentro unas gafas de seguridad que no me molesten con las gafas de ver
Saludos
Dewalt DPG82 muy comodas con gafas.
@@ivanmirandawastaken Gracias!! Las probaré
Excellent music choices, makes watching your videos even better! :D
Amazing job Ivan. But you need a more sturdy base mount to mitigate vibrations (concrete?)
wonder how well the fine tolerances on that would be with creep and thermal expansion of the pla? looking forward to seeing how it holds up
This should be available as a kit. I've been procrastinating about buying a CNC mill for decades.
I am just upset I never heard "Spacer!" during the entire build.
And he used a hammer AND a mallet.
What do you do with all the machines you build?
You should make an automated tool that can produce these tapped extrusions that you use in every 3D printed project.
And cut them to exact length at right angle
My water cooled spindle had a ground pin that went nowhere. I only found that out when troubleshooting weird issues
Very very cool Ivan might I recommend a piece of literature to help with your machining. The machinists handbooks has so much great information in there it is prefect for most of what you are going to need. everything from calculating feeds and speeds to calculating gear geometry and material sciences truly a required bit of kit for anyone who wants to machine
Im thinking of building this Ivan its brilliant well done. Now you need to add/build a rotary table and you are sorted
He quedado sorprendido de este proyecto, y lo voy a hacer pero tengo unas dudas:
1.- En la compra de los planos viene incuidas las parte que hay que imprimir en la impresora 3D?
2.- Que tipo de impresora es necesario, dimensiones? Tipo de filamento?
3.- Alguna recomendacion que me hagas para iniciar este projecto ( especificaciones de motores, router, etc...)?
Muchas gracias y felicidades por el canal
I wonder what the tolerances are with something like this.
Could you add a thermal sensor near the bit that if it hits X temperature, it'll squirt 3-6 pumps of IPA on the bit? Maybe give it limitations so it doesn't just constantly do it though.
I have a mill rrally similar to this ivan i gound that cutting the speeds in half from 24000 RPM to 12000 helped amazingly
I would like to see the cut quality in aluminum using the single flute, nice slow feed cutting strait lines(the wall finish). It doesn't sound like there is a ton of vibration which seems impossible given the wrong linear rails, hollow aluminum and plastic holding it all together. I'd say I'm most impressed by the spindle but not the grounding of said spindle.
I'm very impressed that you can cut steel!
some supplier: so how many aluminium profiles do you need?
Ivan: YES!
cast the whole bottom into concrete so it has some mass. Use roughing endmills and then a finishing one especially if you are going to use a ball end mill and consider encoders so it know when it skips steps.
How long did this project take you to design and film?
5 days design, 11 days build and film, 4 days editing..
2022 and stil making amazing projects!! continue to inspire bro! your projects are awesome.
You already incorporated the 4th axis. Love it all. Keep going my friend!
Please could you tell me what type of filament you have used for 3D printing this part in cnc? And also what is the machine 3D printer you are using ?
You definetly earned a sub here, also with giant 3D printed stuff! Awesome man
Real life iron man..
Thanks for bringing these kind of amazing stuff 🙏👍
Wow! Crazy project! I need a CNC machine and I was thinking about making one myself... I'm not sure I should do it. This is more complex and time consuming than I thought. Anyway, congratulations for another incredible build. 😍
As cool of a project as this is you could buy an actual milling machine for the cost of the profiles!
I have been through several iterations of milling machines in the past few years and in the long run I just ended up buying an industrial milling machine and have finally found my machining happy place. I had a few table top mills that I converted that did nice work but ultimately I wanted to make many big parts and went all in. The table top mill conversion is an excellent route for someone looking to get somewhat serious about making aluminum parts.
That being said, I have scratch built machines and understand they joy of making the machine itself. This is kind of a tedious route to take however.
Ivan, I just need to say thank you again for all your awesome videos. I really love how you improved over the past years. You truely mastered your craftsmanship AND video editing. Love your content so much. Everything is just perfect. Thanks!
Nice work! I love it! I wonder how are tolerances on steel parts you made? How much does it flex?
what speeds and feeds and cutters did you find where best for steel and aluminium?
Every time I see him build stuff with a fresh stack of that extruded metal. I think he is some kind of maker king, living a lavish life a wood using peasant like me could never afford.
I see your using a er collet, is that what the spindle uses or might be a R8 collet holding the er collet? I have a reason for the question.
ER11
@@ivanmirandawastaken oic, kinda figured it was. The reason i asked was if it was R8 like a Bridgeport mill you could chuck the end mill higher and not be extended like that and have much less chatter. But no matter that is a amazing little mill that i would have said not possible not to long ago.
Great project - amazing what it does using 3d printed parts, now you can cut them properly in aluminium 😊😊😊
Sweet project, now add a motorized axis for the tilting and this thing gets even more cool 😎
Dude, I thought the same thing when I saw that. I hope he does😳
That was my first thought when I saw him tilt the head. "Just add a ball screw and a motor and you get a fourth axis". But then I thought about it. Can the CAD software make use of that functionality? When reading up on CNC mills the fourth axis is always referred to as the A-axis, and is defined as having the workpiece rotating around the X-axis. I seems it would take a lot of tinkering to make the controller and cad software understand what to do with a fourth axis that tilts the head and has quite limited movement.
I think thats gotta be the smallest and cutest CNC mill I’ve ever seen
Buenas, la configuración de la Duet 3 podrías subirla a algún sitio?
Really cool project! I wonder how accurate it is.
Amazing! I'm interested to see if the 3D parts hold up after a few weeks of machining. I would also recommend an MQL system. I installed one on one of my small CNC machines and it completely transforms it. And getting some single flute cutters may be a good idea as they seem to work better with machines that aren't as ridged and that have slow cutting speeds.
Hi, Do you plan to extend for 4 Axis. and thank to continue show excellent machine.
That looks beautiful !! Any chance of creating a diy 5 axis cnc in the future ??
why did you make it only cnc controlled? isnt the whole purpose of a mill like that to be able to hand crank the axis so you can cut a piece without having to plan it in software before?
What an incredible video again. A beautiful machine. Have you considered adding some sort of vacuum next to the bit to recover dust and scraps....help keep everything clean?
Nice JOB. You make it look so easy... =D Glad you got into other materials besides plastics. Thx for sharing all this on youtube. I spent weeks shimming up my lathe headstock to get it to run true... Anyways, the editing is amazing. Keep up the good work.
