In this video I ll be building the enclosure around the machine. I have used 3030 aluminium extrusion to construct the frame and 4mm polycarbonate for the doors and front panel. I used a cheaper (but arguably less safe) material for the sides where people are much less likely to be stood if a cutter tries to escape I also make some rail extensions and install bellows on the X and Y axes, as well as begin to mount the spindle clamp to Z axis. In the next episode i ll be mounting and wiring up the Chinese 3KW ER20 spindle DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building a mill requires a much bigger mill to get the axis surfaces flat and parallel. By using aluminium tool plate (which is in theory premachined flat) and bolting the critical components rather than welding, it should be possible to avoid any machine work. After all, I m buildin
