CRENO Drilling of satellite panels

Trochoidal drilling

Description Photos Video PDF

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.
