A single-station CNC microfinishing system processes a family of 68 aerospace control surface actuation shafts to better than 0.1 Ra, while creating a functional surface for the component. Other tribological surface parameters are used for this post-grinding application on HVOC (tungsten carbide) coated steel shafts.
A new design CNC microfinishing system by IMPCO Microfinishing polishes the critical cylindrical bearing journals of a range of different size crankshafts to micron tolerances consistently and automatically without the need to manually change and reposition the tooling, reducing changeover time from many hours to a few minutes. The company says…
