3-Axis CNC Mill Project
After spending a few weeks contemplating ideas for a new hobby project; then longer deciding on a design I was happy with I finally got my hands on the Aluminium extrusion profile wanted to build the frame.
Aims are to have a complete unit, machine base and storage, 3 axis CNC control with Mach3 software, A3 paper size capability, High precision with zero backlash, hardened linear rails ball screws and stepper motors and finally a special purpose milling spindle.
First making a sketch of the idea:
Then realising things look a lot smaller on paper when I get the aluminium home:
Anyway, first up is to end tap the profiles required M8, thankfully its extruded with the 6.8mm hole required for such:
That done:
It was on with marking out the holes to assemble the frame:
And then on with drilling them:
