3D Printed Superabrasive Wheels: Optimizing Surface Finish for Complex Geometries
A turbine blade with internal cooling channels. A surgical drill bit with helical flutes. An aerospace impeller whose vane geometry changes every few millimeters. These parts share one grinding headache: conventional wheels can’t reach everywhere they need to. 3D printed superabrasive wheels are changing that equation, and the surface finishes they deliver are surprisingly good.
