Trochoidal drilling Le Creno has a strong knowledge in drilling of satellite panels. The Creno drilling process is accurate, reliable and trusted by internationally recognized companies such as Airbus, Nexeya and ISRO wich have been operated a 3 axis Creno for years. Also, Creno is currently running test on robot at our site in France with a major satellite builder. The high accuracy needed, the brittle characteristic and the cost of the aluminium panels required a rigourous precision and leave no room for error. The goal of our solution is to drill up to 30 mm (1,18”), have an accuracy of 0/+0,03 mm with no ovalisation and no skin deformation.
The orbital drilling head can be operated on 3 or 5 axis to overcome the interpolation operation and thus ensure the quality of the holes. This process, because of reduced efforts, is easily transposable onto robot cell. Jointly with a leading satellite manufacturer, trials are being done to study the feasibility to apply the process onto robot. So far, results are conclusive and would offer new perspective of machining.

Trochoidal drilling The orbital drilling head is developed in partnership and is based on the principle of trochoidal machining (from Greek Trochos=wheel). It can be installed on a 3 or 5 axis machine and on a robot cell via a HSK interface. This allows to realize very accurate Orbital head holes while limiting cutting efforts. • Interface HSK63-HSK50 A or F That divides by more than ten times • Weight 3.9 kg the drilling efforts and reduces the • Realization of holes H7 from Ø 2 to passing. We then obtain very 14 mm (0,07” to 0,55”) accurate holes with no deformation, • Power 250 W even on thin and fragile composite or • Speed 10 000 to 80 000 rpm aluminum materials.
