The demand for shafts of submersible engines is met by Meva with an innovative response to the execution of the notched end. Enhancing the rolling process by using a CNC high-powered, hydraulic rolling machine and with a deep study on the geometry of the incremental rollers, Meva carries out the notching via cold deformation rather than by the traditional chip removal techniques. This notching offers obvious advantages: it improves the coupling with the low roughness factor; it eliminates sharp edges of the notches, and increases the durability due to the surface hardening from the modification of the crystalline structure.
The range of shafts: 3"- 4" - 5"- 6" is perfectly suited for the Nema norms.
