    Need to work on this 2mm bit.
    I already use the rouging bit to hog out most of the material. Just need more square holes.




    Here it is from the other side.

    Well you can't make a square hole with a round bit, so if you need it more square use a smaller bit.

    ...or overcut into the corners and have a bezel to hide it!

    That is why I step down to a 2mm bit.
    All the holes are different in that I tried different things with them.

    The middle one worked the best as the buttons are not fully square themselves.

    Maybe its wiser and easier to drill the corners first. Then pocket with the bigger bit.

    Not perfect but I think I have got it down pretty well.

    I don't have a 3D probe yet so whenever I reset the machine I am obvious out somewhat.
    The last operation of cutting out the case was well out for some reason..





    I am working now on setting up a spoil board underneath the stock to then super glue my stock to.
    This means I am not cutting out something floating in mid air.

    Just another bit of aluminum stock will do that I can then glue my work stock onto with super glue?

    Well superglue worked really well.
    Surprised how quickly the two bits stuck together as soon as I got the air out of the gap.
    Much better than cutting in the air.






    Main problem atm is the water.
    Thinking of building a dedicated table for the machine which is basically a drip tray that I can then have doors on each side and all the stuff bellow like the controller, spindle cooling res, cooling water etc.
    Means I can flood cool too. Which will be quieter than using the air compressor.

    Thoughts?

    We are cutting steel on mills with mist so not to use coolant and you are going backwards. Cooling with liquid is nice for a production setup but for home? The less, the better. Mist is better for home. Do it properly as i have made it and there will be no problem. With one nozzle you can cool up to 25mm bits.

    Thinking about it you are right.

    Going to make a bed for the CNC that can hold the water that comes off the mist.
    I actually had the bottle about a meter above the cnc the other day and just the water alone worked fine by the looks of it.
    No air just gravity fed water.



    Anyone tried these?

    There are 2 Flute ones but only in the US from the looks of it.
    I need to put a nice round edge on my product housing and these look to be the only thing available.
