Custom machining solutions for the energy and nuclear sectors
Precision control for critical parts in highly demanding sectors
The Pacte law and recent developments in nuclear safety have reinforced the need for manufacturers to guarantee the robustness and traceability of their equipment. In this context, CRENO supports major players in the energy and nuclear sectors by designing multi-axis CNC machines, robotized cells and mobile equipment adapted to large metal parts and sensitive environments.
Manufacturers in the energy and nuclear sectors operate in an environment where safety and regulatory compliance are non-negotiable. The manufacture and maintenance of large components, often subject to extreme temperature, pressure and radiation conditions, require customized machining solutions that are precise and reliable over the long term.
Mobile machines: on-site intervention to limit downtime and control risks
Parts of energy or nuclear facilities, such as containment vessels, reactor structures or pressure vessels, are often too large or too sensitive to be moved.
CRENO designs mobile CNC machines capable of operating directly on site, in installations, to carry out machining operations on very large structures, while guaranteeing sub-tenths precision.
This solution reduces handling operations, minimizes downtime and ensures that tolerances are maintained even on parts subjected to extreme conditions.
Key benefits :
- Reduced downtime: the machine moves around the part, minimizing plant downtime.
- On-site safety: limiting handling of critical equipment in sensitive or irradiating environments.
- Consistent precision: machining of large parts with sub-tenths accuracy, thanks to dual encoders and on-board control devices.
