Quartz glass polishing technology refers to the process of polishing the surface of processed quartz glass to make it flat and smooth, in order to improve the quality of quartz glass and better apply it to various fields such as optics, electronics, semiconductors, etc.

1、 Polishing effect

Polishing is an important step in quartz glass processing, which can improve the smoothness and accuracy of the material, giving it better optical properties. By polishing, small defects and imperfections on the surface of quartz glass can be eliminated, further restoring its transparency and meeting the imaging clarity requirements of various optical systems.

2、 Polishing process

The polishing process of quartz glass usually includes two stages: grinding and polishing. During the grinding stage, abrasives of different particle sizes are used to gradually remove the unevenness and defects on the surface of quartz glass. Subsequently, it enters the polishing stage to make the surface smoother and more delicate, meeting the requirements of precision optical components.

3、 Polishing method

The polishing methods of quartz glass are mainly divided into two types: cold polishing and hot polishing:

Cold polishing: a mechanical polishing method. By using high hardness abrasives, specific liquids, and high-speed rotating polishing discs, tiny defects on the surface of quartz glass are ground until the surface smoothness meets the requirements. Cold polishing can remove small surface defects without causing material deformation, and is suitable for polishing materials with high hardness and good toughness such as quartz glass.

Hot polishing: Polishing using the principle of chemical reactions. Under high temperature and high pressure atmosphere, the surface is treated with various factors such as abrasive, atmosphere, temperature, etc. to achieve polishing effect. Hot polishing can better control the surface shape and accuracy, and is suitable for forming and polishing materials such as quartz glass.

4、 Application of Polishing Technology

Quartz glass polishing technology has a wide range of applications in various fields:

In the field of optics: Through polishing processing, the surface accuracy of optical components can reach sub micron or even higher levels, ensuring precise transmission and imaging of light.

In the field of lasers and optical communication, high-precision optical cavities and fiber connectors can be manufactured to ensure stable laser output and efficient transmission of optical signals.

High end optical instruments, such as astronomical telescopes, microscopes, etc., require precise polishing to prevent damage to the optical surface, ensuring stable and accurate performance of the optical instrument.

Quartz glass polishing technology is an important processing technique that can obtain quartz glass products with high-precision and low roughness surfaces through different polishing methods and process parameters, meeting the needs of various application fields.
