This little logo was milled in acrylic with the Proxxon high-speed spindle on a Tormach mill using a 1/8" carbide engraving bit, 60° & 0.005" tip at 0.010" DOC, 10k rpm, and 6 ipm feed.
I've got flood coolant but decided to just use a shop vac to continuously suck the chips from the cut for this job.
