Optical Machining

An optical grinder is a machine specially used for processing optical parts. Its basic principle is to make use of the relative movement between the grinding wheel and the workpiece to continuously grind and polish the surface of the workpiece, and finally obtain very high flatness and smoothness.

Application of optical grinding machine processing

Optical grinding machines are mainly used to process precision optical components, such as prisms, lenses, mirrors, filters, laser light paths, etc., for laser and optoelectronic devices, semiconductors, precision machinery and astronomical instruments and other industries.

Compared with other processing methods, the biggest advantage of optical grinding machine processing is that its optical machining accuracy is very high, which can reach the sub-micron level, so that the surface topography and wavefront error of the workpiece can be controlled in a very low range, thereby improving the optical quality of the optical system. performance. At the same time, grinding machine processing can also produce very fine surface microstructures, thereby realizing the customization of different optical properties required by optical design.

The basics of optical grinding machine processing

Optical machining requires the following basic conditions:

Precise mechanical structure

Optical grinding machine processing requires a very stable and precise mechanical structure, so as to ensure high-precision grinding machine processing. The processing and assembly of mechanical structures requires a high degree of skill and management experience.

High quality grinding tools

Manufacturing and dimensional control of the grinding wheel is critical, and the abrasive material of the grinding wheel also needs to be of extremely high quality. Grinding wheels are usually made of diamond or silicon carbide.

Sophisticated control system

The importance of optical grinding machine processing lies in automation. Through computer-controlled programs, the positions of tools and workpieces on the grinding machine can be precisely controlled to limit the surface topography and wavefront errors. Therefore, a control system with very stable, high resolution and fast response is required.

High quality fixture

Fixtures are often one of the most problematic places in the manufacturing process. Optical grinding machine processing requires the installation of high-quality fixtures. The shape and design of the fixtures need to take into account the specific properties of the workpiece to ensure the grinding of its surface and the smooth transition of the multi-axis device.

In general, optical grinding machine processing is an important technology in the field of high-tech processing. This processing method is based on precision machinery, high-quality grinding wheels, precise control systems and high-quality fixtures, and can produce high-precision, high-quality optical components that exceed the capabilities of traditional machining.
