    Maybe it'd be a good idea to show the guys here some pictures of the kind of work you want this machine to do? High speed spindle are great if the work can take advantage of it.

    If you take the width across (X), split into 6. The rails are basically _|____|_ So Space, One, Space, Space, Space, Space, One, Space.

    The type of stuff that I want to do is fairly simple, motorcycle bar risers, RC car parts etc.

    Have you seen drill tap machines like these? https://www.youtube.com/watch?v=-fcWdMVVbEs
    Most have BT30 spindles at ~10,000 rpm

    Lovely that. If I can get anywhere near that Ill be happy.

    I am thinking BT30 if possible. My Denford VMC is BT30. Does anyone have any experience with the Chinese / Asian supplied BT30 (with drawbar) item that sells for around $1800?

    Check out http://www.cells.com.tw/en/products.php?m_sn=6 I haven't used CELLS TEC but I believe they make good spindles, both motorised and non motorised.
    Stuff like http://www.aliexpress.com/store/prod...643490383.html might be worth looking at.

    Are you more interested in built in motor spindles?

    Cheers,

    Thanks, will take a look. Interested in all things at the moment.

    That spindle looks decent. The Posa website actually looks like something proper and not the typical crap you see. Certainly worth a look. Have you ever used one or seen one?

    Started with the layout for the electrics. Ill mount onto a stainless plate most likely, this was just on MDF to get a feel for the size and get the basic X axis movement sorted.



    A quick video, nothing is really calibrated but the motor seems happy to spin to 4000 rpm. Its a Panasonic 1.5KW motor and A4 drive powering it.

    A number of hours later, some marking, measuring, drilling, fitting, wiring and we have the bulk of the electronics mounted.

    isn't that panel a bit tiny for your machine? don't you want more room in case you missed something

    Its 800 x 800. There is space to the right of the servo drives. I doubt much more will be needed, that is virtually all the electronics I need. The spindle drive goes to the top right, there is enough space for at least another 2 servo drives if I want to do more axis.
