Orbital Ball Lapper
Orbital Ball Lapper/Polisher
2014
To perfect the Fitbionic Foot, we needed very smooth ball joints. We couldn't seem to get what we needed from external vendors, so I designed a piece of industrial equipment to provide a mirror-surface finish on an internally spherical surface. It was a great success.
Project Highlights:
-
119 unique paths, plus hand motion for true random
-
Used OTS diamond lapping balls
-
Fail-safe design
-
Mirror finish (~5 microinch RMS)
-
Sphericity held better than .001"
