The rolling process consists of a cold deformation known as cold working. The artifact is stressed beyond its elastic limit with a modification of the crystalline structure to a fiber structure that follows the profile of the rolled section. The absence of the crystalline incoherence ensures a high resistance to breakage.
The applications are aimed at obtaining gear shafts for submersible motors, for endless screws, for transmission shafts, and specific implementations for the transmission of power.
The advantages of the process lead to an improvement of the surface roughness with a drastic reduction in the friction between sliding surfaces also benefiting the noise in the transmission. The plastic deformation also involves the hardening of the worked surfaces with the work piece's reduction of wear.
The modern hydraulic CN rolling ensures maximum accuracy and dimensional reproducibility. Low roughness and low friction are synonymous with superior efficiency and durability of the transmission.
