Decided to try something I’ve never done before since I’ve only ever operated manual mills in the past.
I tried a double-sided PCB… I had quasi-success due to a problem with my alignment holes during the design process. I also messed up the math a little bit for the effective diameter of the V-groove engraving tool that I used, so wasn’t getting quite as wide a cut as I meant to.
Anyway, it was 7 operations with one tool change and one manual operation. The only reason I had a manual operation is because I don’t currently have a way to use my tiny drill bits with the DW660, so just did shallow pilot holes with the machine. The DW660 is a disappointingly limited tool in terms the shank sizes it accepts. Has anyone come up with a clever solution for adapting different collets for the 660? I may end up making my own, but it’s a lot of work I’d prefer to not do if someone has already solved the issue.
I’ve added pictures of each operation along with a few of the mounting and flipping. I learned a lot doing this. It was fun.
