Bare Fiber Polishing Machines

Bare Fiber Polishing Machines are specialized machines for polishing the end face of bare optical fibers. Bare fibers are optical fibers that are not protected by an outer cladding and are typically used in the manufacturing and assembly of optical devices. The quality of the endface of bare optical fiber is critical to the transmission and processing of optical signals, so the polishing process is needed to ensure the finish and flatness of the endface.

The main function of a bare fiber polishing machine is to polish the bare fiber endface mechanically and chemically to achieve specific surface quality requirements. It typically includes the following key components and features:

1. Polishing pads and fixing fixtures: used to fix the bare optical fiber in a suitable position and to bring its end face into contact with the polishing pads.

2. Polishing Head and Wheel: Used to apply pressure and rotational force to rotate the end face of the bare optical fiber on the polishing pad, thereby grinding and polishing the end face.

3. Liquid Polishing Compound System: Provides liquid polishing compound and ensures that it is uniformly distributed between the bare fiber end face and the polishing pad to improve polishing efficiency and surface quality.

4. Rotation Control System: Controls the speed and direction of rotation of the polishing head and wheel, as well as the pressure applied, to achieve precise polishing of the endface.

5. temperature and humidity control system: some advanced bare fiber polishing machines may have temperature and humidity control functions to ensure that the polishing process is carried out under suitable environmental conditions.

Bare fiber polishing machines are commonly used in the manufacturing and assembly process of optical devices, such as fiber optic connectors, fiber optic packages, and fiber optic sensors. By using a bare fiber polishing machine, the finish and flatness of the bare fiber end face can be improved, thus ensuring efficient transmission of optical signals and stable device performance.
