    Who has a nice solution for the housing of the two switches, the speed knob and the display?

    I have to say Im very impressed with your micro mill, Michel. Even more impressed when I think about the tolerances you've cleared and what machinery you have available to achieve those tolerances. I know the challenges I face on modern CNC mills and you've gone and made this on small-ish hobby machines - they seem more capable than I ever thought but Im sure it also comes down to your technique and skills 🤗
    Also, just pause the video at 15:35

An I.C engine such as the Webster or 6 cycle Oddball. All in all, have some great fun with the little machine and then ship it to me. 😊

    Grinding the spindle taper on-site was beautifully done ❤, i'm wondering if you have found the 16mm ID bearing for spindle or you took the spindle to 15mm on the lathe and used standard bearing🎉.

    • @Michel-Uphoff
      @Michel-Uphoff  3 дні тому +3

      Where the chuck sits in the bearing, it was 22mm in diameter. I reduced that to the 17mm needed for the bearing. That was not clear in the video because I forgot to record this machining. In the scene right after tightening the chuck on the mandrel, you see suddenly a completely machined chuck.

      @@abdelrahmanelmasry9699 No, I won't do that. It is made of run of the mill cold rolled steel. It's not hardenable, however I could case harden it, if I had a big enough oven for it. But even then I wouldn't do it, because this steel would warp like crazy when heated that much.

    Regarding the housing for the knob & switches: How about something that is magnetic? Something you can attach to the column? That way you're more flexible with regards to positioning. Or alternatively some quick release mechanism. But I think the column is generally a good place. I think somebody else asked this in a previous video, but would you generally recommend the ff 500 bl? Were all the milled parts machined on the ff 500? And what is the maximum shank diameter? It's 13mm right? Thanks a lot in advance. I will watch this video in full extent later today with a cold beverage :)

    • @Michel-Uphoff
      @Michel-Uphoff  3 дні тому +3

      A magnetic box is indeed one of the possibilities I'm pondering about.
      The ff 500/BL is a beautiful, well-functioning and accurately made machine. But it also has a few weak points. In particular the headstock is in my opinion of inferior design. I have made a few videos about this machine and some improvements. I hope you have seen them?
      As you can see from my videos, there is more possible with this machine than meets the eye. If you need a precise machine of small size and weight (45 Kg), I think there is no alternative that is better.

My question about the shank size is probably something I should ask Google... but it seems the maximum for ER20 is 13 millimeters.

    But what is the point of such material savings for such a small machine? Both the machine column and the base and the spindle mount could be an order of magnitude more massive and, accordingly, rigid. And all this without a significant increase in cost and the increase in the space occupied by the machine.

    • @Michel-Uphoff
      @Michel-Uphoff  День тому +2

      I didn't do any material savings. These are the dimensions and design I had in mind from the beginning, without paying any attention to the costs. It seems to me to be a fairly balanced whole, considering that we are talking about a micro mill here. The only thing I would change, in retrospect, is the column, which is now 40x40mm. I could have made it 50x50mm without any further design changes and that would make the column even more rigid. Furthermore, as mentioned in the video, I would not make the quill like this anymore. In fact, I already have an improved design ready for that, which I will send along with the drawings.

      ​@@Michel-Uphoff Well, it's pretty useful to make complex shapes, with interpolation you can save the need for various fixtures, It would increase the number of operation you can do.
      Since it's small the parts involved aren't that expensive 3 closed loop steppers, 3 ballscrews, 3 endstops and an electronic board to interface with linux cnc, for example mesa card, or an old pc with the parallel port and a cheap breakout board with opto-isolators.

Series production would be another reason, but that is not relevant here. I simply prefer turning a hand wheel to tapping data on a keyboard.

    I think the spindle has too small toque. Why you didn't make a transmission? You could make a solid spindle head and a small motor with a belt drive transmission. It would be a more robust solution and would not complicate production too much compared to the your version of spindle.
