Machining and anodizing a titanium superman pendant Media

Published: 12 years ago

This video is a little long and boring if you're not into machining, so skip to the end to see the finished product.

In this video I show you how I made a really sweet christmas present for my 5yr old nephew, a CNC machined Titanium superman necklace! Why? Why not! I've had a few sheets of Ti sitting around for months so it was finally time to get off my butt and try to machine something from it. It's been a great learning experience and has definitely taken the edge off of my fear of machining Ti.

In the vid I machine all the pockets and profile with an 1/8" 4 flute carbide endmill, broke one just a few minutes in to the video and had to re-code the part and start over. Then I switch to a 1/16" 2 flute carbide endmill to get deeper into the corners and make the logo much more defined, this operation took a long time but was well worth it. Lastly I used a 1/16" ball mill to engrave my nephew's name into the part. Then I broke it away from the large sheet and filed the edges, then sanded the surfaces smooth with 320/400/600 grit sandpaper, then tumbled in ceramic media for 8 hours, then anodized the part to 92v revealing a really wicked deep green. He LOVED it!

Now I can't wait to make something else from titanium!
