Abstract: An extraction tool for extracting a shim located in a turbomachine and provided with a through-hole, includes an extractor pin configured to be inserted into the through-hole of the shim; a first gripping member with a first distal end intended to be positioned opposite the through-hole on a first side of the shim and arranged to retain a first end of the extractor pin; and a second gripping member including a second distal end intended to be positioned opposite the through-hole on a second, opposite side of the shim, and arranged to retain a second, opposite end of the extractor pin, after the extractor pin has been inserted into the through-hole of the shim.

Abstract: A guard for a part to be shot-blasted and having an axis of revolution, the guard including: a cover and a chamber shaped for receiving the part to be shot-blasted; the chamber having at least one planar section with a shape matching at least one planar section of the cover; two side guards mounted on the part to be shot-blasted and having one degree of freedom relative to the chamber and the cover, wherein the cover, the chamber and the two side guards form a box for sealing the shot, the box including a window for projecting the shot, the surface of which matches a portion of a surface of the chamber.

Abstract: A precision positioning device extending along an axis to be maintained in a first opening of a mechanical part, includes an axial element provided with a passage, a nut, a support and a moveable element, the axial element being integral with the support, and including a first screw thread for mounting the nut on the axial element, the nut providing an axial stop blocking the axial movement of the axial element relative to the nut, the axial element having an end portion including a deformable cylindrical male profile, adapted to cooperate with the inner circumference of the first opening, the deformation or radial expansion of the end of the axial element being driven by the action of the insertion of the moveable element in movement in the passage of the axial element in the direction of the end of the axial element.
