Embodiment Construction
[0021] Referring to FIG. 1 , FIG. 1 shows a cross-section of a rotor 1 of a turbomachine compressor, including blades 2 mounted on the rotor 1 and a compressor disk 3 facing the blades 2 inside the rotor 1 . Each blade 2 has a root secured to the rotor 1 using techniques known to those skilled in the art, and the blades extend as far as the tip, or tip 4, to which the repair method that forms the subject of the present invention is directed.
[0022] Referring to Figure 2, which is a radial cross-section of a blade tip, the shape of the blade tip is a sharp edge 4, the thickness of which is determined by the expected mechanical strength characteristics, and its radial extension has a thinner portion 5, which is referred to by those skilled in the art as The grooved tip is used to form a seal against the casing surrounding the compressor. This thinning of the groove tip is such that it inadvertently penetrates into the abradable material to which the casing is incorporated, so ...
