We have been working through some fun finishing challenges this week with a new metal. We are talking about the big W - that is, tungsten!
Specifically, this is for our Singularity Disc. Ramping up manufacturing of this hard, brittle metal has given us some unique challenges in the realm of surface finishing.
Our original process was CNC turning, but because the metal is so hard to work with, we were getting a very inconsistent turned finish where the metal “picks up” and leaves slightly deeper radial marks in the discs.
So, we have gone back to a classic favourite of ours: a ground finish. This gives us the perfectly flat, balanced, and smooth surface we want to get these discs spinning like it’s 1765!
