Abstract (en)

[origin: WO2019155347A1] The micromechanical clockwork part (1) is cut from a plate-like silicon substrate. The cut edges of the part comprise portions intended to serve as contact surfaces arranged to slide against corresponding contact zones of another micromechanical part in a clockwork piece. The cut edges have a ribbed surface comprising an alternating set of ribs (21a) and furrows (23a), the ribs and the furrows being straight and each contained in a plane parallel to the plate. Moreover, the ribs and furrows which the cut edges have form a stepped pattern on the cut edge, with first intervals (25a) in which the spacing separating the ribs from one another is equal to a first distance, and at least one second interval (27a) in which the spacing between the ribs is equal to a second distance different from the first distance.
