METHOD FOR PRODUCING A COMPONENT

摘要

#CMT# #/CMT# The method involves modifying the structure of an area of a substrate to make the area more selective, and chemically etching the area of the substrate to selectively produce a component i.e. pallet anchor (101), where the pallet anchor is released from the substrate. The structure of the area of the substrate is modified by a laser, where the substrate is made transparent to the wavelength of the laser, and the substrate is made from one of a monocrystalline material, polycrystalline material, polymer, ceramic or glass. #CMT# : #/CMT# An independent claim is also included for a pallet anchor. #CMT#USE : #/CMT# Method for manufacturing a component i.e. pallet anchor of a timepiece (all claimed), in a substrate. #CMT#ADVANTAGE : #/CMT# The method allows a recess to be formed under the surface of the pallet anchor as the material of the substrate is chosen to be transparent to the laser, thus allowing the laser pointer to any point on the surface or below the surface of the pallet anchor. The material of the substrate is made selective so that the chemical etching operates only on the material having been modified by the laser, thus enabling production of complex internal recesses. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a pivot system. 101 : Pallet anchor 200 : Recess 1011 : Upper face 1012 : Lower face 1013 : Circular wall.
