Analysis of cutting technique of monochrome femtosecond laser in watch escapement wheel and escapement fork

The escapement wheel and the escapement fork are two vital components in a mechanical clock, responsible for transferring power to the balance wheel or spring system, thereby controlling the precise timing of the clock. Manufacturing these components requires extremely high precision and excellent surface quality. Femtosecond laser cutting technology is the ideal choice for the production of escapement wheels and forks due to its high precision, low thermal effect and complex microstructure processing capability.

Femtosecond laser cutting in the escapement wheel and escapement fork manufacturing specific application technology:

1. High precision gear cutting:

The gear of the escapement wheel requires extremely high precision, and femtosecond laser cutting can achieve precise gear cutting by controlling the pulse energy and focus position, and the error can be controlled in the sub-micron level.

2. Complex geometric escapement fork processing:

Escapement forks usually have complex geometry and microstructure. Femtosecond laser cutting allows precise control of material removal to form fine structures and edges, ensuring their functional and structural integrity.

3. Fabrication of microstructure:

Tiny channels and holes in the escapement wheel and escapement fork can be precisely manufactured by the multi-photon absorption effect of the femtosecond laser. These microstructures can optimize the energy transfer path and improve the working efficiency and durability of the components.

Femtosecond laser technology was used to cut and fabricate the escapement wheel and fork. Through strict parameter control, the following results were achieved: The escapement wheel and escapement fork cut with femtosecond laser showed significantly improved timing accuracy in the test, and the error was reduced to less than half that of traditional machining methods. The edge of the escapement wheel and escapement fork after cutting is smooth, which reduces the need for secondary processing and ensures the consistency and reliability of the product. The heat-free zone ensures the mechanical properties and stability of the escapement wheel and fork, extending the service life of the product.
