    Default Looking for somebody with CNC milling machine

    Hi guys.

    I'm from Europe but I have a friend in Australia (Tasmania) who needs to make some parts on CNC milling machine.
    And while it's too expensive to send him things from EU, I'm looking for somebody down there with a milling machine to help.

    It's all about aluminium sheet metal parts up to 10mm thickness.
    If you have some anodising shop around, even better!

    I don't think it's suitable for big companies, better some small shop / garage guy.
    It may be a long-term cooperation.

    I can even supply ready-to-run NC code.
    Anybody interested in some work for the machine?

    Thanks!

    A picture or a rendering of the product might help people to decide whether they have the machinery needed.
    Cheers

    OK here it is. Front-panels for electronics.
    Thanks.

    Thanks Roger.

    As electronics sizes.
    Can be 100 mm up to 500 mm (most common).
    Basically machine working area 500 x 500 mm is enough.

    High RPM spindle is quite essential (at least 20-24k RPM).
    Vacuum table as well.

    Too long for me.
    You don't need those sorts of revs: 2,500 rpm would do fine. (Or you would need many many kW on the spindle!)
    You will not be able to hold that down with a vacuum table: it will have to be clamped.

    Cheers

    For milling ALU and especially for tiny tools (down to 1mm diameter or 0.2mm engraving tool) high RPM is the best, if you want to produce it in reasonable time and nice surface finish (usually without finishing operation). Alcohol cooling is the very best here.
    Panel on the photo was done on a vacuum table. High RPM provides you small cutting forces as a very good side effect so it will stay in place. But sometimes yes - you need to hold it little bit better but it's still possible to use some tricks on vacuum.

    I'm doing this kind of milling for over 15 years now, so I tried many approaches

    Ah - I would go for a 6 mm carbide cutter instead. Tiny cutters tend to get BUE and snap.
    I avoid alcohol cooling as it can give problems with blood alcohol content! Air blast & mist.

    Cheers

    Yes Roger, for milling bigger pockets or the panel itself we use 6mm cutter too. And we run it at 35k RPM and feed 3m/min Balanced 1-flute cutter is the only choice here.
    Alcohol is very good but of course you can do it also with other cooling methods.

    I rather think that you are talking about a serious commercial machine. Most of the participants here are hobbyists, with somewhat smaller metal-cutting machines. The wood routers some have are much bigger, but would not suit.

    Cheers

    Yes, you are right, RPM 35-40k is not so "hobby".
    But with a friend of mine we built a machine with 24k RPM (2 kW) spindle and it's still a quite common DIY in my opinion.
    Anyway thanks for your input.

    I love your dismissive nature... like why ask the question if you think you already know?

    Read my original question please.
