    Hello Everybody I found your (Our) site about a week a go and have just registered. I am looking to build a cnc mill capable of machining Ali/Brass:wave:

    Welcome Peter.
    Can you be clearer about your goal?

    Sorry if you know all this already, but here are some thoughts you might find useful.

    Do you mean a router, or a true mill? Generally with a router the cutting head moves in X/Y/Z and the workpiece remains stationary, which is good for large wood/plastic/foam items. In a mill the cutter moves in Z, but the workpiece moves in X & Y, whcih is better for smaller items, particularly metal ones. Obviously there are cross-overs between these.

    For cutting metal (with any reasonable speed or depth of cut and accuracy) you need rigidity which is generally hard to achieve with a router arrangement without incurring a lot of hassle and cost. A true mill is characteristed by a lot of mass in a big casting to give the rigidity, and therefore most CNC milling is done by converting a conventional off-the-shelf mill rather than building from scratch (although I have seen some ground-up builds based on a lump of steel girder). This is likely to be the cheaper route overall as well.

    Thanks all for the warm welcome, In reply to irving2008 I hope to build a gantry type milling M/C based on a welded steel chassis (X750, Y500, Z125) I have got a fair idea of how it will look,but still in the drawing stage.
