Engraved Emerson skulls on CQC-7 Media

Published: 12 years ago

I engraved a bunch of different sized skulls onto this set of grey Emerson CQC-7 scales. It was very tricky because the scales are not absoperfectly flat, and the engraving is incredibly shallow, so either it shows up too deep or doesn't cut at all. But in the end it turned out great and looks amazing. Let me know what you think!

For my machinist followers:
I used a carbide 4 flute 0.032" ball endmill to do the engraving, I love these little things. 0.002" deep (in some locations haha, way deeper in others), 4500rpm at 15ipm which was feeding a little fast, 5-10ipm would produce a nicer finish, but this is perfectly acceptable. I'd like to be able to use more RPM's, thinking of installing an 1/8" air pencil which spins at 56,000rpm at 90psi!!! But even down at 20,000rpm I'd be able to feed at 40ipm which would be great.
