Sturdy DIY CNC Mill made from Fibre Concrete
HTML-код
- Опубликовано: 14 окт 2024
- Most hobby CNC machines are made from aluminum or even wood. Sturdy alternatives such as casted epoxy granite machines are expensive and require a reinforcement skeleton. Here I show an alternative, using concrete with fibreglass snips (fibre concrete) I built a sturdy machine that does not need an additional steel skeleton. It combines the advantages of casted machines (precise inlayed connections, resistance to vibrations) with a much lower price and ease of construction. Hope this video inspires your own CNC design! Thanks for watching.

i guess Im randomly asking but does someone know a method to get back into an Instagram account??
I was stupid forgot my login password. I appreciate any assistance you can offer me!
@Reed Baylor I really appreciate your reply. I found the site through google and im trying it out now.
Takes quite some time so I will get back to you later when my account password hopefully is recovered.
@Reed Baylor It did the trick and I now got access to my account again. I'm so happy:D
Thank you so much, you really help me out!
@Hayden Brett you are welcome :)
I would be extremely interested in learning about how you built the molds for the casting and any tips you have for that! Thank you so much!
back here 3 years later and still wanting to see more about the machine and how you built it.
Impressive and beautiful at the same time. Thanks for sharing. And lots of CNC fun.
I'd love to see and hear more details like which concrete and fibers you use, the ratios, and how scraping or polishing worked.
...nice video.. It would be nice to see more video's of the construction of your CNC machine. Nice job by the way.
very good idea :) Consider making a video series about it if you still have the build footage.
I'd like more videos about your awesome CNC machine!
Looks very nice and would welcome more détails on the build
Very inspiring!
3 years later, are you still satisfied with the result?
Any warping / shrinkage / anchors issues?
very nice buil! I'm interested to see videos of the mold-making, mold design, and building process.
Impressive machine, good job. 👌
This is a sick build and I hope you put out more videos about it
I'd love to see more on the construction. Great machine, how does it perform on metals?
Hi, thanks for sharing. For beginners that come from computers ambient, it is very useful to learn of the methodology the measure and align at micron level. Thanks.
Very cool! You should definitely continue with the videos. You should keep improving the machine by making parts with the machine...
I would love to see more on this.
I agree with the comments. Nice build and would like to see more info about it.
Myself is collecting parts for my build.
We want more!!!
Bro you are genius kudos to you, i wnat to build one for my self can you help with that
great idea ..
NIce, jetzt musst nur noch den Tisch und das ganze Holzzeug ersetzen, damit das nicht resoniert. Sonst bringt dir ja die Beton CNC nix :-) Grüßle CNCPRINT
Hi,
Awesome buil! little bit more information regarding mixture would be appreciate...
Hello, so impressed, i would love to know more, as i am thinking on building one at the moment.
awesome idea: just two things: 1-make a video about milling capabilities and 2-make several video tutorials building one from scratch... you will boost your channel!!!!
Can you explain how you made the concrete mix? As in what materials did you use and how much of each.
Very nice! Interested in building a similar machine
nice! however, epoxi granite machines do not require steel reinforcement. in fact, the epoxy only stabilises the matrix, the stiffness comes from the quartz or granite infill. when properly cast, those pebbles directly contact each other, so the epoxy granite has the stiffness of the granite (which is much highter than the stiffness of the epoxy matrix)
In addition to what you said, a huge reason people go for epoxy granite bases is for the damping factor, whereas concrete will just be behave like a metal otherwise it would just crack.
@@preddy09
This not true, UHPC has also very good dampening properties.
Woow, that looks like a beast!
Ive been planning a concrete CNC for over a year, In 1917 they built hundreds of concrete lathes to make artillery shells, and destroyed them after the WW I
Nice machine. Can we se it Cut aluminium and maybe Steel ?
I have considered this for years. Every time I look into it I end up over specing everything to the point that it becomes unrealistic to start. The size of components you have used seem reasonable, but please can you tell me if it is possible to machine regular mild steel on this machine?
No. The spindle is too fast. The Z-axis is probably also too weak.
Not this design, but concrete body with some cast iron or steel plates can definitely cut mild steel easily, and spindle speed is not at all a problem but it's a benefit if used with coolent for more feed rate in less time.
@@grimkarltun7846 That spindle is definitely capable of cutting steel.
@@MegaCoolshot Cutting and cutting well are 2 different things. The bearings would go banana when milling steel for too long; plus the overhang. There is a reason spindles for steel are beefier.
Please, please follow up with more information on it! I was under the impression that concrete is less than ideal because it is likely to shrink when cured.
Can you please show us in great detail how exactly you scraped or sanded the planes for accurate surfaces. Also what is the accuracy and repeatability like of the CNC when milling?
How long did you let the concrete cure before putting the parts together?
What stiffness did you measure for the machine?
Hello I'd be interested in the design choices for the frame, I'm planning on building something similar with ultra high performance concrete and similar hardware I just don't know how to start designing the frame
Definitely great idea for experimenting with designs cheaply but finally does not compare to the overall performance benefits of epoxy granite.
its actually way better than that, but its all useless and pointless if you use a paper thin mdf table, all rigidity for nothing
Queria perguntar se o concreto não contraí e deixa as guias chumbadas com uma brecha? O concreto não trinca com a vibração da máquina?
How did you calibrate the cnc with laser sir... Please guide.. i also want to make one
Please show us more about your machine, testing, does it do aluminum or steel, im looking to use your method and build a concrete CNC
I would be interested in this.
Is this still being monitored? Could I possibly message you somewhere for some more info?
Tell me how do you get the linear bearings aligned? Thank you..
...nice and informative video thanks. ...but 5 microns flatness, ....um, ....I don't think so!
Hi, Can you share us the composition of the concrete you use? Such as the weight percentage of the concrete/fiber/sand/water? Thanks.👍
More videos please
Please, i'm extremely interested!
1:19 5 microns across the whole surface? I'm pretty baffled by this considering in most builds a super flat surface that is also perpendicular seems like one of the hardest things to achieve.
Avesome job :)
0:43 what screw nut is this?
Olá poderia me passar os ingredientes para fazer esse concreto a estrutura e como fazer ?
Any chain is only as strong as its weakest link. The wood needs to be replaced with aluminium or steel.
Steel wool!
Yeah, sign me up
More videos bro
Tell me more plssssssssssssss
+ vids news???
Who always tells people concrete machine beds need reinforcement?
It's complete nonsense.
If you're dead set on using fibers - just clad it in a quasi isotropic carbon fiber laminate. Compound beams from Cf clad polymer concrete test surprisingly good considering the comparably tiny amount of fibers and resin.
Thought to be a result of the strengthening of the concrete itself by confinement as well as by taking the tensile loads.
Your background music is not only pointless, but the same volume as your voice, making it illegible. A shame, as this could be an interesting video.
I think he is Dead now. RIP 😢
0.2 mm on load 20 kg? Minimum is 0.01 mm on load 10 kg :(
it is rly good on wood mounting plate , now he can make aluminium mounting plate and then he will have 0.01 on more than 10kg load :)
@@ErtsenPlayGames We can only guess. The author seems to have decided not to show the machine anymore.
