A method of manufacturing a timepiece bearing by laser cutting of a crystalline material.

摘要

The invention relates to a method of manufacturing a timepiece bearing (1) made of a crystalline material, natural or synthetic, from which are obtained by cutting a plurality of discs (3). The discs (3) to be performed are obtained from a mother plate (2) shaped like a half-moon, and surface of predetermined dimensions by laser cutting, as circular paths (7) or semicircular (8 ), tangential to each other, the thickness of the cut close, so as to reduce material losses only to gaps (9) formed between the peripheries of circular discs (3) and obtain a maximum number of disks (3 ).
