Abstract
An applique for horology includes a visible upper surface and a lower surface for resting on a dial or a structure of a timepiece. The applique also includes at least one foot projecting from the lower surface for attachment to the dial or the structure. To manufacture the applique, in a first operation, a profile or bar is provided in which blanks of the feet and of the lower surface are machined prior to cutting the profile or bar in a second operation. Then, the upper surface is re-machined with at least one final diamond-polishing operation. During the first operation, at least two machining operations are performed in a cross so as to form a blank of each foot with a polygonal contour having facets.
Claims8
A method for fabricating an applique for horology comprising an upper surface intended to be seen by a user, and a lower surface for resting on a dial or a structure of a timepiece, and at least one foot protruding from said lower surface, for attachment thereof to such a dial or such a structure, the method for fabricating an applique comprising:
- machining, in a first operation, a profile or bar to produce a blank of said at least one foot on said lower surface;
- cutting, after said machining, said profile or said bar in a second operation;
- and
- then, after said cutting, re-machining said upper surface with at least one final diamond-polishing operation,
- wherein, during said first operation, said machining is performed in a cross so as to form a blank of said at least one foot with a polygonal contour having facets, and
- wherein, after forming said polygonal contour and prior to performing said final diamond polishing operation, said at least one foot is journaled to machine a cylindrical surface that is configured to attach said applique to a support in a timepiece.
A method for fabricating an applique for horology comprising an upper surface intended to be seen by a user, and a lower surface for resting on a dial or a structure of a timepiece, and at least one foot protruding from said lower surface, for attachment thereof to such a dial or such a structure, the method for fabricating an applique comprising:
- machining, in a first operation, a profile or bar to produce a blank of said at least one foot on said lower surface;
- cutting, after said machining, said profile or said bar in a second operation;
- and
- then, after said cutting, re-machining said upper surface with at least one final diamond-polishing operation,
- wherein, during said first operation, said machining is performed in a cross so as to form a blank of said at least one foot with a polygonal contour having facets,
- wherein, during said first operation, a finishing machining operation is performed on said lower surface, and
- wherein said lower surface is made curved.
