Estimating the term…
The invention relates to a drilling system, in particular for two assemblies on which it is mounted. It makes it possible to drill holes through an overlap area, made using a drilling tool passing through a locking orifice formed on a tool holder of the drilling system, the drilling tool comprising a bearing mandrel as well as an expandable ring closely fitting the mandrel along a tapered contact surface and adapted so that a relative movement along a tapered contact surface. According to the invention, a relative movement is applied between the expandable ring and the mandrel so as to create, following locking of the ring in the locking orifice, a displacement of the mandrel bearing against the overlap area, through the locking orifice and towards said overlap area in order to exert pressure thereon, by displacement of said drilling tool relative to the tool holder via a sliding connection.
A drilling system comprising:
The drilling method carried out using the drilling system according to one of the preceding claims, characterized in that, for each step for drilling a hole, a relative movement is applied between the expandable ring (56) and the bearing mandrel (51).
