I MADE A STEEL CNC MILL FROM SCRATCH (desktop version)

1. Making a machine tool out of thin wall steel tubing is never going to yield a good surface finish. Steel tubing cannot dampen the vibration. You can get better results from a machine made of the European standard linear aluminum rail you've used in other projects, even when using 3D printed connectors and mounts made of PLA.

   The most important factors for better surface finishes are: 1) a frame that is rigid and incorporates material to dampen vibration; 2) a spindle with good bearings and low total indicated runout; 3) a tool holder that matches the diameter of the cutting tool (to avoid introducing runout); 4) a properly trammed head; 5) a cutting tool with correct geometry for the material (the ones you used were suitable); 6) proper speeds and feeds; and 7) rigid work holding.

   That said, I do appreciate your enthusiasm and creativity.

2. Si rellenas el interior de los tubos de la estructura con resina o cemento ganarás estabilidad y reducirá enormemente las vibraciones

3. very nice

4. good sharing…i will make design for this CNC Mill in my channel later

5. great work….amazing…how much price for build all item machine….

6. Whow great! I'm dreaming to have a CNC mill for soo long but can't afforn to buy one. Maybe sometime I can build a similar one. Thanks very much for this build video which inspired me.

7. Good stuff ??

8. Have you ever heard of therm drills?Works better than rivet nuts.

9. Hi,I am very curious of how ouy level the bed and make sure it's accurately perpendicular to the spindle for the whole x,y travel.

10. find a good welder who can teach you 😉 not the worst ive seen, but you could do alooooot better for sure 🙂 and tig is proberly the hardest to learn to master straight away, compared to mag / mig .. they are a little more forgiving 😉 TIG is ALOT of heat in 1 single place…. a good thumb rule is for every 1 mm its around 30 amps… so 2mm would be 60 amps !. but ofcourse people are different, but depends on your speed and how fast your filling it with the filler..

    OH yeah and you made to much space between each tube… something like that it should be max 0.2 or something, if not just 0.0 🙂

11. Ivan Mirand THIS is amazing how can one get the Cad files? i cant find it on your website. this model

12. O kadar kaynağın üstüne titreşimi yedikten sonra bütün profil borular çarpılır. Hassasiyet namına hiç bir şey yok

13. I don't have a crane..but one can dream!

    LoL

14. nice job

15. Thoroughly enjoyed your vid, with I had hour skills.

16. what is the parts list

17. This is dammed impressive. I honestly wouldn't know where to start! Great job!

18. Мда собрал неведомую зверушку из говна и палок.

19. These tiny flimsy rails is a weak point now. Also need to protect them from the metal chips.

20. Pretty good build but, the X,Y seems really small.

21. Fill the frame of the machine with cement or resin mixed with small stones. This will take out/damper high pitch/high frequency vibration and create nicer surface finish.

22. Nice frame but looks like this is gonna be lacking of accuracy and parallelism, and the upper gantry is gonna need more stiffness and rigidity cause threaded rivet and such few screws are gonna move and micro shift due to vibration

    But in the end that an awesome work, I would never have done better ????

23. forgive me, you did a good job, but a machine built with tubular steel and welded will have a very high margin of error, in this way you cannot build such a thing.

24. share the link of its 3d drawings, thanks

25. Good Video except for the shite music.

26. If this is scrap metal, then my machine is made of shit and sticks)))) No offense bro)

27. Way cool for a man without a degree?
    I guess the adage of hard work will succeed every time….

28. You have to paint the frame. It will look really bad all rusted.

29. Hi, do you know about any hopefully free open source program to create toolpaths? We have been struggling with Luban, I don't know if it can work. Fusion is too expensive and complicated, I am working on introducing these technologies for education and job creation in developing countries, so cost and ease of use are critical

30. Сварка-как насрано!!!

31. So inspiring. I've just progressed from using a small 3018 CNC to my own build C Beam CNC. I've never welded but I want to try now

32. 2 Flute end Mills will eat aluminum like butter with less friction 4 flute end mills are better for steel and high torque cutting

33. It is aluminium

34. Scratch? Fast? Easy? U fake

35. what's the runout?

36. What ae the dimensions of the square metal profile you used for the structure?
