GE Aviation was in the process of developing a new Jet engine for aerospace industry. They made a decision based on studied, to improve the surface finish of their turbine blades for this engine in order increase fuel efficiency. Because of our extensive experience, Bel Air was engaged in a year long study, along with 2 other companies in the world to facilitate the improvement of the surface and all associated equipment and process technology for the upcoming production process.

If you are unsure what equipment and media you require to achieve your desired surface finish, thenĀ send us your part, and we will evaluate it and provide you with a metrology report.
