Our company

CRENO: A Key Partner for the Global Aeronautics Industry

CRENO has been developing innovative machining solutions, combining machines and processes, since its foundation in 1978 in Annecy, France.
For the last fifteen years, the company has been focusing on specific processes in the aeronautics sector for which we have designed highly differentiated solutions. We are currently working with major aeronautics stakeholders mainly in Europe, North America and Asia.
Going beyond our initial expertise in highly accurate robust, multi axis CNC machines – with 3, 5, or more axis – dedicated to "soft" materials such as aluminum or composites, we have developed advanced and efficient innovative processes, specifically for:

Multi-drilling “acoustic drilling” of composite nacelles

Ultrasonic cutting of various types of honeycomb structures

Milling of composite parts

Routing and drilling aluminum sheet stacks

Innovation is central to the CRENO strategy. Each year we invest a significant share of our turnover in developing technologies adapted to the needs of our customers. Since 2015, we have been working closely with partners such as Stäubli, Siemens and Pracartis to develop highly accurate machining solutions in robot cells to complete our range of multi-axis machines. These robotic solutions for the composite and aerospace industry are more efficient than ever before.
In addition to our new robotic production systems, we offer local support to our customers thanks to our technical support and sales teams based in France, North America and Asia.



Customized and Turnkey Solutions

Our vocation is to provide you with efficient turnkey production equipment perfectly fitting your needs. We provide solutions that cover the entire process: machines, expertise, software, tools, control devices, clamping devices, programs, etc.

A Committed

Our commercial, technical and administrative teams are dedicated to providing you the best solution. Every day, we listen to what you need and strive to obtain your total satisfaction.

A Long-Term

Wherever you are, we provide you support and improve your processes through on-line assistance, preventive and curative maintenance, upgrading and retrofitting.
