SFR - Stress Free Recessing
-
- Beyond Precision Machining
Stress Free Recessing or SFR in short, is an advanced version of electrochemical machining process. SFR, a registered trademark of INTAI, is especially effective for all metallic parts that cannot be manufactured feasibly using conventional manufacturing processes. It is also a realistic choice to perform SFR on parts achievable by conventional processes due to its flexibility.
