Abstract
A cam-type timepiece component (1), which has at least one portion of substantially planar shape, having a material hardness greater than or equal to 600 hv, this portion having a thickness greater than or equal to 350 microns, or even greater than or equal to 400 microns, and comprising at least one functional flank (3) which is substantially perpendicular to a main surface (2) of this portion and has a roughness ra of less than or equal to 50 nm.
Claims20
A method for manufacturing a cam-type horological component, wherein the method comprises:
- cutting of a thick strip of material with a hardness greater than or equal to 600 HV, by the combination of two different laser beams within a liquid jet or by one laser beam of a femtosecond laser to form at least one functional flank of the horological component,
- the horological component having a thickness greater than or equal to 350 microns, and
- performing a termination action.
A cam-type horological component comprising:
- at least one part of substantially flat form made of a material having a hardness greater than or equal to 600 HV,
- the part having a thickness greater than or equal to 350 microns, and comprising at least one functional flank substantially perpendicular to a main surface of the part and having a roughness Ra less than or equal to 50 nm.
