CNC Lathe Turning build - Part 1
HTML-код
- Опубликовано: 9 фев 2025
- About a year ago, we, Damien Dando & Luc Dando, have started the project of designing and building a CNC Lathe Turning on our spare time.
My father, Luc Dando, is doing all mechanics related parts and I, Damien Dando, do all electronics and control system parts.
CNC machine control is done with the opensource software Machinekit.
This video shows the current progress of our project.
Technical characteristics:
8 positions automatic tool changer
Z axis travel: 300mm
X axis travel: 150mm
Spindle power: 3kW
Oh man, I could watch that tool changer rotate for a couple hours. It was sooooo smooth and had a satisfying sound
Hyper impressive realisation!
Eager to see more of this machine, keep the good work :-)
Thanks Fred!
Spotted some nice details, very cool build! Keep up posting more about this ;-)
Wow... Amazing!!!! Thanks for sharing!
Oooo very nice! New diy youtube cnc videos seem to come in waves of 5-7 years
If you are going to yse regular concrete, you may deplace water with chemical fluidiser for shrinkage prevention and for self levelling. You may use glass fume, fiber,nylon or metal pieces like paper clips , fly ash for increasing strength and elastivity. You can find vids on youtube
Looks very impressing.
Martin Berzerker Thanks! :)
amazing bro
This looks like great project. Must say it looks like it can do some precision work. I believe we all would appreciate more videos about. Have you evaluated using a mineral casting base?
sivertvk thanks! The philosophy is also to build the machine with low tech that are available at lower cost and at local scale. For example, we try to minimize out of shelf parts from Asia, etc.. and also avoid proprietary technologies but use opensource instead. For those reasons, my father is planning to make the base in concrete. There is design in the mechanics to allow some fine adjustment.
We aim to reach ~0.01mm. Also the ball screw we have are not the rectified expensize ones kind but there is possibiliy to correct that in software even if the default is not linear. This is possible because we use opensource software (Machinekit). I'm currently working on the software to implement&add realtime torque feedback for the spindle and all axis :)
I will definetly post videos when there will be more things to show! ... but that might be in several months since we do that on spare time ;)
@@damiendd09 unbelivable project,very happy to watch it and since im starting to build mineral casting cylindrical grinder from scratch(like STUDER,but manual) i will be very happy to see more of your work.u got me (sub).wish you the best

That's an awesome lathe build Damien. How's your progress going with it? Keen to see another video. Regards, Aaron.
So far, the project has been moving faster than making youtube video about it :D I finally found time to complete and upload the second video: ruclips.net/video/sB7fwDViwqw/видео.html
There is more to show but I need to find time to do the video editing ;)
Wow that is indeed a very impressive project. Well done! what size are your linear guides?
cool gemacht kompliment....
Hello! Tell me please. What program controls the machine? How has such a tool change system proved itself in use? Usually the pneumatic cylinder pushes the revolver. You have a stepper motor doing it. Does the motor not skip steps when fixing the revolver? If the stepper motor moves the revolver all the way, it probably can not finish the step. Am I right?
Hi! I use Machinekit (ex-LinuxCNC) to control the all machine. The machine is not use intensively but the tool changer works pretty well so far!
There is 2steppers, one to unlock/lock the tool changer which is spring mounted so it lock it-self when steppers are not energized. And another stepper for the rotation which obviously shall be moved only when the tool changer is unlocked. There limit switch to detect when it is locked/unlocked so in case a stepper miss step the system will find out and abort the tool changing procedure. This typically never happen as motor are slightly over sized (except of course there is an obstacle on the way).
Additionally there is a basic RFID tag on each position of the tool changer so the system can know which tool is in on initial power up and anytime.
I use an Arduino due to control the all toolchanger and this arduino communicate with Machinekit via a serial interface.
@@damiendd09, thank you very much for the detailed answer! Perhaps I will dare to try to assemble my own analogue of a revolver tool holder. I wish you creative success ! All the best!
Wow, very nice build! By the looks of it, I am feeling that this will be an Epoxy Granite project? Do you have more updates on the project? Good luck!
We choose to go for regular concrete instead of epoxy granite. We did the first tests few months ago and I will come with some news hopefully soon! I have started to put a video together but need to find some more time to complete the video edit!
@@damiendd09 I've seen quite a few concrete builds. Have you added any additives or out of ordinary stuff to the mix? Well I'm looking forward to see the new video once you find time for it. Subscribed ;-)
Wow!
👍👍⭐️⭐️⭐️⭐️⭐️💪💪
Could u please share details of turret?
Do you have any documentation of the build?
Im most interstet in schematics of the ATC turret.
Im thinking about building a machine myself and Your design looks nice
I would be thankful if you get in contact with me.
Hi Njkisn, it's my father who did all mechanical design&manufacturing of the mechanics.
For the all electronic parts I have done, I'm willing to opensource it but for the mechanics my father is not sure.. There are parts that are not so easy to make and quite few tricks to be aware and we haven't really done video showing all that..
@@damiendd09 Im able to work to prints if they are properly made and for tricky parts.. That's what I do. Its my hobby but I also work full-time as a machinist and we have great experienced guys at work and fkn expensive CNC machines.
So please throw parts at me I cant handle. Im on for the challenge xD
And Im anyways not interested in copying your exact design, but rather take what seems appropriate for my machine and implement it in a new(maybe just something modified) design.
Thanks for the answer and I will appreciate every kind of documentation you might give to me or the whole internet :D
@@TheDayzman ok I don't have the machanics design myself but I'm gonna ask my father if he has something usable that could be shared.
@@damiendd09 Great Thank you very much
wouldn't that be safer if pneumatically actuated?
very nice project. Congratulations!! Are you planning to open source the project?
thanks! the project is built with opensource philosophy in mind but I haven't found much time yet to do more video and share about the build design details.
At the moment, we are more focus on completing the build and if things goes well we should be able to do first turning tests by the end of this year!
@@damiendd09 Thank you very much for your reply. It will be a game changer for the community if you decide to publish your design as an open source platform. You can profit in this way like Cura did with their 3d printers and I will be one to follow your progress and maybe buy one. If you need any help with the documentation, just let me know, please.
I can also help producing videos and graphic design if you send me the information and the clips. I want to help. I am a mechanical engineer
Do you use VDI or BMT life tooling?
Great build! Do use mesa card and Linux CNC controller software? The motor type look likes the one Tormach is using.
Hi, I use Machinekit (which is more or less same as Linux CNC), I run everything on a BeagleBone Black so I don't need any mesa card or extra particular hardware. The electronic you see in the video is just voltage level adapter and opto-isolation interfaces.
Which control are you using mate? Good craftsmanship there
Rinku Singh Thanks! I'm using the opensource motion controller software Machinekit running on BeagleBone Black and ClearPath servo motors on all axis&spindle
u r genius man
Здравствуйте! Как с вами можно связаться ?
Just my opinion only. The designing does not appear to be anything new ...mechanically. There might be some operational electronic improvements.
However, I am NOT a fan of this rotational positioning design. There are only EIGHT points of positioning ....seating into what is probably soft steel ...very small points of contact. We don't know how much force is being applied to these seating points, and the turning forces placed on primarily one side of the seated points. We also don't know if this entire circumference area will be protected/sealed from contaminations (coolant/swarf).
When there are readily available gear-type couplings such as "curvic", which have far superior performance advantages, it makes no sense to come up with something like this design ....unless the point is just to be different. Yes, it works, but will it work "just as good" ...for a long time? I think not. Dad needs to reconsider the design.
This video is four years old ....I'll have to investigate more recent videos. Well worth following.
.
kindely tell me which software is used for it?
I'm using Machinekit opensource software :)
you make your own turret tool change. you have the plans. Thanks
will please share cad drawing
I think cheaper to buy it if you consider your time... But nice job
