Sturdy DIY CNC Mill made from Fibre Concrete

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!

@haydenbrett125 2 года назад

@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.

@haydenbrett125 2 года назад

@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!

@Bu5H84 5 дней назад

back here 3 years later and still wanting to see more about the machine and how you built it.

@8710ify 3 года назад

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!

@trcwm 19 дней назад

We want more!!!

@OhHeyTrevorFlowers 2 года назад

I'd love to see and hear more details like which concrete and fibers you use, the ratios, and how scraping or polishing worked.

@robertling9872 Год назад

Impressive and beautiful at the same time. Thanks for sharing. And lots of CNC fun.

@liquerinfrnt 3 года назад

This is a sick build and I hope you put out more videos about it

@tinchodias 2 года назад

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.

@jan888banan 3 года назад

I agree with the comments. Nice build and would like to see more info about it. Myself is collecting parts for my build.

@ElektrotekSolutions 2 года назад

@aion2177 3 года назад

very good idea :) Consider making a video series about it if you still have the build footage.

@justone8572 3 года назад

great idea ..

@iamthebiker 2 года назад

@mortaldrumming 3 года назад

very nice buil! I'm interested to see videos of the mold-making, mold design, and building process.

@victorgalvez927 3 года назад

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!!!!

@davers1610 3 года назад

I'd love to see more on the construction. Great machine, how does it perform on metals?

@stewartfrye 3 года назад

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

@gac231 2 года назад

@Texaca 2 года назад

...nice video.. It would be nice to see more video's of the construction of your CNC machine. Nice job by the way.

@ErtsenPlayGames 3 года назад

Avesome job :)

@snagle87 3 года назад

Very cool! You should definitely continue with the videos. You should keep improving the machine by making parts with the machine...

@eetukuikkaniemi9822 3 года назад

@CNCPRINTBLOGSPOT 2 года назад

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

@TeslaAtoms 3 года назад

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)

@preddy09 2 года назад

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.

@warmesuppe 2 месяца назад

@@preddy09 This not true, UHPC has also very good dampening properties.

@sto2779 2 года назад

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?

@Bu5H84 3 года назад

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

@kdesign101 3 года назад

Nice machine. Can we se it Cut aluminium and maybe Steel ?

@TheFabricator03 3 года назад

Can you explain how you made the concrete mix? As in what materials did you use and how much of each.

@preddy09 2 года назад

Definitely great idea for experimenting with designs cheaply but finally does not compare to the overall performance benefits of epoxy granite.

@JohnSmith-pn2vl 10 месяцев назад

its actually way better than that, but its all useless and pointless if you use a paper thin mdf table, all rigidity for nothing

@bobweiram6321 3 года назад

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.

@perspectivex 3 года назад

How long did you let the concrete cure before putting the parts together?

Queria perguntar se o concreto não contraí e deixa as guias chumbadas com uma brecha? O concreto não trinca com a vibração da máquina?

@sayaarmstrong 3 года назад

Tell me how do you get the linear bearings aligned? Thank you..

@PhilipStubbs 3 года назад

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?

@grimkarltun7846 3 года назад

No. The spindle is too fast. The Z-axis is probably also too weak.

@rameezsheikh7576 3 года назад

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.

@MegaCoolshot 3 года назад

@@grimkarltun7846 That spindle is definitely capable of cutting steel.

@mihailfelixdumitresc 2 года назад

@@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.

@heinzhaupthaar5590 3 года назад

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.
