Nice little CNC mill you've made there =) For cutting aluminium - you can use regular household isopropyl alcohol. Its far less messy than any oil-based cutting liquid and its wonderful for aluminium
Thank you for taking the time to voice it over. I find epoxy builds to be very interesting to witness every builders manner of A to Z. Great build and result!
Thank you for sharing this video and for sure you have designed and built an interesting compact sized cnc mill with a Epoxy base. It would be really great if you can do a separate video of the design of the wooden base for shaping the epoxy and most importantly how you assembled the metal frame using different sized bolts and spacers, taping the holes and you mentioned about applying bees wax to prevent the expoxy from sticking.
Thanks, I sadly don’t have a lot of footage or images building the frame and have gotten rid of the material as well. But once I will cast another part, I can go more into detail
When people design and Build a CNC it's all about the; rigidity, speed, resolution, motor power 💪 When people start USING the CNC... Then it's all about; flood coolant, chip clearance, tool setting, noise and mess reduction 😎
@@lukasOtis yeah and it's not just for the cooling, if it is set up right the liquid blows all the chips out of the grooves and cavities, so the cutter is not munching up all the chips which causes a whole heap of problems. Very nice machine build, by the way. 👍🙂
well said. You spent months designing, building and aligning the CNC into sub 10 microns, ONLY to realise that you need proper air to fluid ratio, chip protector on ballscrews and a STURDY base heavy steel structure to position the machine
nice work man ,been contemplating doing a similar project myself looks great, tho unless the gas springs bring the enclosure door above head height i would probably just have the door open against the wall horizontally rather than vertically as it is now
very cool! I didn't notice you doing it but have you tried slowly spinning your dial gauge on an arm maybe 100mm from your spindle to see if your spindle is 90 degrees to the bed, it looks like that's most of the surface variance in your test pieces.
i had tried that while using shims and a hammer to try to get the spindle as close to the 90°C as possible. After a while I didnt know anymore if the spindle or the base is now more out of plane. But I havent checked it after surfacing the table. Think I will do that, thanks
Well done and nice video. Will you support the Z axis in the future since it has a lot of weight with the Epoxy Part? The 7,5% Epoxy and 95,5 % Solid was a typo, or ? I saw one video some time ago where these round spindle got a second clamp at the top which increased rigidity.
Thanks! That slipped through, the 7.5% Epoxy is correct and with that it should have been 92.5% solids. As it has been fine the last 2 years, I am not sure if a support is needed. A second clamp was originally planned and still is somewhat. Haven’t gotten around to it though
Hi. If you ever make another epoxy concrete would be interesting to see if adding Graphite to your mixture would make it stronger. According to experiment made by Tech Ingredients channel it should be 50% stronger "Making Graphene could KILL you... but we did it anyway?!" at 41:00. Love you Machine BTW. 👍
Thanks! The link unfortuanetly doesnt work anymore, you should be able to find it listed as „milling cutter 300R C10-20-60-2T“ using APMT1135 inserts which I purchased seperatly
I was going to ask if you noticed any distortion due to heat during casting but since you mentioned casting reached 30 deg and you diluted epoxy with granite I guess you didn't experience any heat issues?

That's good to know. Do you use a mister set up? No real risk of fire?

I was indeed thinking about flood cooling a couple days ago

man the timelapses are so satisfying.
Excellent build, thank you for sharing details on the epoxy granite material.
Thats a nice cnc! please make more videos
That looks like really fine machine. Looking forward to the next part :)
Thanks! should be ready in one or two weeks
Fantastic first video! Can’t wait to see what you do next!
Nice. Looking forward for electronics video!
Interesting project! Good luck and please keep us updated. Subscribed.
Unfassbar cool, Kommentar für den Algorithmus :)
I'd consider removing the belts on the steppers and drive the screw directly. You'll get better results
nice work man ,been contemplating doing a similar project myself looks great, tho unless the gas springs bring the enclosure door above head height i would probably just have the door open against the wall horizontally rather than vertically as it is now
Thanks! And thats a good point. Above headhight should be doable, I think the door can open more than 130/140°, which I will try to make happen

Very cool CNC machine 🎛️
Really cool build, well done!

Great project, getting anything like that remotely square is quite an achievement :)
👏👏👏👏
Awesome !

Запаса рамы хватить тягать шпиндель на 7 квт, с подачей тумана резать будет прилично.

Good point, I think adding in some fibres of any kind could be beneficial. Did not think about that
Do you have a link to that 2 flute face mill? Great video!!

No, luckily did not had any issues with heat. I think it’s the combination of a somewhat long curing epoxy and having less than 15% in the mix.
Хорошая машина, почему закладные из алюминия?
What is the tool you're using at 1:12? I've been looking for a tool like this for a small spindle for a while
Got it from overseas and it’s listed as „Right angle milling cutter 300R C10-20-60-2T“ using APMT1135 inserts I purchased separately
5:35 has 103% material
the 7.5% Epoxy is correct and it should have been 92.5% solids
