CNC. That is what started this post. Today, I fired up the CNC mill, and made a simple fitting for my Bolton 7, which involved some accurate deep drilling in aluminium. I LOVE CNC!! Drilling 3mm diameter holes through 16mm material, automatically, centre drilling, then deep drilling 1mm peck at a time and automatically clearing the chips, with positional accuracy of 0.001mm. Fantastic! Cannot wait to get more into this.
