    Epoxy granite vertical mill cnc

    Few years ago I decided to build a cnc milling machine and today it's almost done. It took a long time to decide what to build. here is the result:

    I had no access to milling machine so the only way for me was to use epoxy granite structure, because the mold can be done using wood from local supplier. unfortunately I loos the picture from the mold. I only have a picture of a test mold that I did before the real one:

    Next pic is the assembling of the horizontal base and the column:

    Assembled with linear rails and ball screws:

    The first version of the table:

    Allining the square on the Y:

    and then the X on the square (and of course the Y):

    First fully assembled:

    With this configuration I did some very preliminary test:

    And I also tryed to mill the table:

    Conclusion was that the temporay spindle headstock is very bad so next step was to upgrade it:

    But it didn't turn very well and the table assembly which was not as strong as I thought, then I decided to upgrade it also:
