  • Manufacturing method and watch component
    Patent number: 11940761
    Abstract: A manufacturing method includes a first repeating step of irradiating a base material with a pulse laser, having a spot diameter S, while relatively moving a laser head and the base material in a first direction, moving the laser head by a predetermined pitch width P in a second direction that intersects the first direction, and repeating irradiation by the pulse laser along the first direction and movement of the laser head in the second direction, and a second repeating step of irradiating the base material with the pulse laser while relatively moving the laser head and the base material in the second direction, moving the laser head by the pitch width in the first direction, and repeating irradiation by the pulse laser along the second direction and movement of the laser head in the first direction, wherein S<P<100 ?m.

  • Method for Decorating Watch Component, Watch Component, Watch Movement, and Watch
    Publication number: 20210402513
    Abstract: A method for decorating a dial includes deeply digging and forming a first groove by repeatedly scanning, in a predetermined scanning direction, a place where laser light is applied to a base material. In the scanning, a depth of the first groove is controlled by the number of irradiation times that the laser light is applied. An area where a depth of the first groove is shallow and an area where a depth of the first groove is deep are present according to the number of irradiation times.
