Abstract
A method of manufacturing a watch component in which while a laser irradiation unit and a base member made of metal are moved relatively, laser irradiation is performed to decorate the base member, and includes a first step of irradiating the base member with the laser to form a recessed portion in the base member, a second step of irradiating, with the laser, the base member in which the recessed portion is formed at irradiation intensity less than irradiation intensity of the first step, to clean the base member, and a third step of performing surface treatment on the base member after the cleaning.
Claims8
A method of manufacturing a watch component with a base member decorated by performing laser irradiation while relatively moving a laser irradiation unit and the base member made of metal, the method comprising:
- a first step of irradiating the base member with the laser to form a recessed portion in the base member;
- a second step of irradiating, with the laser, the base member in which the recessed portion is formed at irradiation intensity less than irradiation intensity of the first step, to clean the base member;
- and
- a third step of performing surface treatment on the base member after the cleaning,
- wherein the second step includes two cases:
- a first case is to irradiate, with the laser, both a first region of the recessed portion and a second region of a front surface of the base member continuous with the recessed portion, and a second case to irradiate, with the laser, the second region, and
- an irradiation intensity in the second case is less than an irradiation intensity in the first case.
