Industrial grade CNC with DIY resources

Industrial grade CNC with DIY resources

Making a big ‘industrial performance’ CNC router, that will work on metals as a mill too.

This CNC machine needs to earn its place in the workshop, so the plan is to make something that can cut 8 x 4 ft sheets and flatten big chainsaw milled slabs, as well as machine aluminum and steel parts.

If you want to check out Frank’s avid CNC videos look here: and for T-slot extrusion machine, see here:

The spindle motor in the video is a 240V single phase Jianken JGL-100mm 3.2kw 24000rpm BT30 ATC. It has ceramic bearings and thus far seems very nice. We chose a 4 pole one, which has somewhat more torque at lower rpm than the 2 pole, but requires an 800Hz VFD. We will do a whole video on this spindle in the future. You can find them here: and if you do buy from them, message them and mention ‘Flowering Elbow’ – you should get a discount.

    Hey Friend, thanks for watching. If you would like to support us, earn our unending gratitude AND get the 3D CAD model to play with, and/or get our metalized epoxy recipe/guide, go here:

    We are in the process of putting together a big document, full of diagrams and details about this machine build. When it's done we will add the links here & in the description above.

    If there is any element of this you are curious about please ASK! We love to hear from you and will reply, and it might be something we write about in the document we're making…

    Peace n Love,

    bongo and sam

    Look forward to rusty ballscrews. You can not touch them with bare hands unless you want them to rust. Doesn't matter what you use to lubricate them, once they have hands on them or the linear rails they will rust.

    for acrylic projects, you'll get much better cuts using an o flute cutter and only cutting cast material. I'm not sure what you were using but i've seen similar off of my machine with extruded acrylic

    When you finally get it all finished I'd love to know just how much its cost in parts and more importantly man hours, that thing is looking really damn good though, and for being built from what you can get rather than very deliberately chosen stock I think its a very impressive looking beast.

    (also if its even remotely possible to move it again, that is one giant and doubtlessly stupendously heavy monolith that getting access to with a heavy enough lifting gear looked rather hard)

    You really should look into getting consistent mist/fogbuster coolant spraying on this thing if you plan on milling aluminum lol. This machine can probably really go, but that lubrication and chip evacuation will be needed. Also, Have you considered trying LinuxCNC?

    Congratulations on a awesome build. This machine will give you years of joy. You are definitely aware of how important it is to start with a great sturdy base. Don’t be scared to move away from Mach 3/4. Although I have been involved for the last 15 years with CNC I realized that the computer based setup with Mach do give glitches. Great for hobby but when you want reliability, do check in future after making some money to invest in a dedicated controller. They are dedicated and will give you very reliable machine with immediate startup. We converted our cnc plasma, router and milling machine to this controllers. Once again great video, great build. You are a creative person and this will bring very creative designs on a router. Very handy when you start doing signs for shops. 😎

    If you left the washing machine motor on the frame whilst pouring the concrete you could have turned it on and vibrated all the concrete into place with no airbubbles

    Maybe it might have helped with the epoxy levelling too? Probably a less powerful motor for that.

    What CAD /CAM software are you using? Also you mentioned Mach3 which uses a printer/parallel port to function. Most computers nowadays don't have that so how are you getting around that problem ? Great project BTW 👍

    it is my understanding from reading hiwin's catalogues and assembly manuals that the linear guide may be pressed against the raised shoulder for the purpose of increasing rigidity; not (necessarily) to straighten the rail (14:05), so perhaps you could add the tapered screw + steel rod arrangement to your machine. i would also like to add that another reason to use a rotating ball nut is to circumvent the critical rotational speed of the ball screw, which is a function of its length and its diameter, as well as the bearing arrangement; a long screw means a low maximum rotational speed, which in turn means lower rapid speeds (18:30)

    Hello Flowering Elbow, do you notice any sound or bump when the bearings travel over your rail transition? I am about to purchase a good ebay deal on 2000mm and 1200mm rails that I plan to combine into 3200mm

    That has to be one of the most cool and interesting DIY builds ever. You had my interest when you build the gantry. I LOVE how what you can get defines much of the design. I can't really wait until you show us more. I also work on limited budget and use a lot of scrap parts, but still go for high quality and precision cuts on my next build. One of my biggest problems is how to make straight mounting surfaces for the rails, when I have no straight reference. I would love to se more of your experience with epoxy leveling.
