hello there,
I am new to this site and am looking to build a cnc machine. I have a few questions. could a well built machine designed for wood be used for aluminum or brass? would it just be a matter of slower speeds and adjusted spindle speed. or would it need to be 'beefed' up to make a more sturdy machine like a bigger spindle motor, or using metal for the framing of the machine? has anyone here done any light milling of aluminum or brass with thier homebuilt wood machine??
thanks in advance, I think this site is great. Ideas being shared with like minded individuals is such a great advancement for humankind...
