摘要:
A method for manufacturing a component in a substrate including: a) modifying a structure of at least one region of the substrate to make the at least one region more selective; and b) chemically etching the at least one region to selectively manufacture the component.

A method is for manufacturing a stone, in particular for a timepiece, from a mineral body of monocrystalline or polycrystalline type. The method includes an ablation step in which the body is subjected to a material ablation by scanning on at least one face of the body using ultra-short pulse laser radiation whose duration is less than one hundred picoseconds, and whose beam is guided by a precession system having at least three axes to at least partially cancel the angle of the laser cone, which is due to the focusing of the laser. A mineral stone of monocrystalline or polycrystalline type, in particular for a horological movement, is likely to be obtained by the method. The stone includes in particular a face provided with a peripheral rim, in particular for laterally clamping an endstone in a bearing.

摘要:
An apparatus for producing holes in a workpiece by means of a laser beam and for coating both sides of disc-shaped workpieces which incorporates two band members guided above one another at a spacing along a predetermined path. This spacing of the band members is smaller than the height of the workpieces. One of the band member has a smooth surface and the other an adhesive surface, and two coating locations are arranged such that one is before and the other behind the aforementioned predetermined path.
摘要:
A method and device for manufacturing a bevelled stone, particularly for a timepiece are disclosed. A precursor is produced from a mixture of at least one material in powder form with a binder. The method includes pressing the precursor so as to form a green body, using a top die and a bottom die comprising a protruding rib, sintering the green body so as to form a body of the future stone in at least one material, the body including a peripheral face and a bottom face provided with a groove, and machining the body including a substep of planning the peripheral face up to the groove, such that an inner wall of the groove forms at least a flared part of the peripheral face of the stone.
摘要:
In order to drill holes in watch jewels or the like a laser beam is produced having pulses in which successive spikes are formed with a substantially constant period, the first spike being greater in intensity than the subsequent spikes which can have equal or diminishing intensities.
摘要:
A method for curing fissures and cracks or the like at workpieces formed of metal oxide materials and processed under high material stress, wherein the workpieces are heated in a furnace to a temperature in the range of 1000* to 1600*C.
摘要:
A laser beam is produced for drilling watch jewels by a resonator and a focusing lens system. The resonator comprises a rod of active material mounted between two planer reflectors and energized by a pulse light source, the spacing between the reflectors being at least 10 times greater than the length of the rod.
