Machining and ultrasonic cutting of honeycomb core The CRENO 2 in 1 solutions has been specifically designed to increase productivity and quality of your products. The 2 in 1 process consists of a mechanical milling combined with the ultrasonic cutting all in 1 machine. The Creneau offers a turnkey solution as well as on multi-axis machines or on robot. For 6 years, the process is used and continuously improved by our R&D department. It offers many advantages such as reduced investment, flexibility, versatility and less floor area occupancy. In only one machine, you can realize complex shapes using mechanical cutting where the ultrasonic cutting would not be suitable. Our machines combined an electro spindle, able to process composite and honeycomb core materials with ultrasonic cutting heads. This combination brings high quality and accuracy to your production. The process offers a traditional roughing and ultrasonic cutting finishing. Both of cutting process are transposable, adaptable and complementary depending on the uses. Advantages of the ultrasonic cutting : - Reduces materials wastes and avoids chips - High profile accuracy - Brings higher part quality with no deformation of the honeycomb structure - Smooth cutting edges (Chamfer edge up to 1 mm (0,04”)) - Increases productivity Creno acquired a real know-how which brings us as a key player in combined machining. Our teams will support you in every step of your project and will help to define the best process for your requirements.

Machining and ultrasonic cutting of honeycomb core The ultrasonic cutting is a process using a very high speed vibration at an ultrasonic frequency (not hearable by the human ears) of a cutting device. The power is created by a generator. The electrical power is then converted by a converter into a mechanical pulse, amplified by a booster and transmitted to a cutting device. Vibrating 20 000 times per second, the cutting device significantly reduces the blade penetration effort into the product and allows perfect control of the position of the products and thus gain accuracy.
