Opinions wanted: Granite milling machine configuration.
Hi all,
I would be interested to hear any opinions about a 4-axis milling machine I am designing.
These are just some preliminary sketches. The dark grey parts are solid granite, screwed together. The light blue bits are the rails. The base is 600mm x 600mm (2' x 2').
I guess one thing I'm worried about is stiffness. Ideally, I'd like the spindle to be nicely positioned directly between the rails, rather than overhanging as it is on the images. But I can't think of a sensible way to do that.
The linear motors and the 4th axis are not shown.
