It refers to the use of 3-micron-thick abrasive film or abrasive paper to grind and polish the optical fiber end face during the manufacturing of optical fiber, optical fiber connector production, and the processing of optical fiber-related devices to achieve specific optical performance and physical index requirements.
Features: high-precision polishing, non-damaging finishing
1. Micro-cutting and mirror effect
Only remove a very thin layer (nano to micron level) on the surface of the material to eliminate fine scratches, burrs or oxide layers and improve surface finish.
Typical applications:
Metal polishing: mirror treatment of stainless steel tableware and jewelry (such as polishing matte surfaces to reflective effects).
Optical components: pre-coating pretreatment of lenses and prisms to ensure that the surface flatness meets optical standards.
Low wear and protective grinding
Friendly to soft materials (such as aluminum alloys, plastics, and glass), not prone to excessive cutting or thermal damage.
Example: Anodizing of mobile phone shells, smoothing of model figures.
2. Suitable for wet grinding
Often used with polishing liquid or water, the liquid removes the grinding debris, reduces particles clogging the sandpaper, and reduces friction and heat generation to avoid material deformation.
Application scenarios: Essential tools in the precision field
1. Electronic product manufacturing
Polishing after CNC processing of mobile phone/camera housing to eliminate knife marks and make the metal frame achieve a "mirror-like" effect.
Surface treatment of PCB circuit boards to remove pad burrs and improve welding reliability.
2. Optical and precision instruments
Final polishing of telescope lenses and microscope slides to ensure that there is no scattering when light passes through.
3. Optimizing the surface roughness of aerospace parts (such as turbine blades) to reduce air resistance or fluid friction.
4. Jewelry and crafts
Fine polishing of precious metal (gold, silver) jewelry, combined with wax polishing technology to achieve a high-gloss effect.
Polishing of natural materials such as jade and amber, retaining texture details while enhancing transparency.
