PWA 36905
Developed by NEMFI with the cooperation of Pratt & Whitney, this process improves  jet engine fuel efficiency and thrust by reducing RA finishes down to single numbers with minimal stock removal.

ISF (Isotropic Finishing)
This unique patented process generates a non directional low Ra surface (using non-hazardous and environmentally friendly chemicals). This process reduces friction and wear on the surface, increases part durability, and improves corrosion resistance.

Rösler’s Keramo Process
This inexpensive and straightforward process creates a high-grade surface finish and has an extremely low material removal rate.  This is a popular process for the aero engine market – for both new components and overhauls including disks, blisks, blades and vanes.
