Publish Time: 2025-02-05
As an important data storage medium, the surface finish and dimensional accuracy of discs have a vital impact on the reading and storage performance of data. In the precision production and processing of discs, ensuring extremely high surface finish and dimensional accuracy is the key to manufacturing high-quality discs.
The surface finish of a disc refers to the microscopic geometric shape error of its surface, which directly affects the reading performance and life of the disc. In order to achieve extremely high surface finish, precision polishing technology is usually used in the production and processing process. In the polishing process, it is crucial to choose the right polishing liquid and polishing disc. The abrasive particle size, concentration and dispersion in the polishing liquid will affect the polishing effect. Generally speaking, polishing liquid with fine particle size and uniform dispersion can obtain a smoother surface. At the same time, the hardness and material of the polishing disc also need to be selected according to the polishing requirements to ensure uniform wear of the workpiece surface and removal of minor defects during polishing.
In addition to polishing technology, dimensional accuracy control of discs is also an important link in the production and processing process. Dimensional accuracy mainly involves the diameter, thickness and data track accuracy of the disc. In order to ensure high-precision dimensional control, advanced mold forming technology and precision injection molding process are usually used in the production process. Mold forming technology can ensure that the disc obtains a stable shape and size during the injection molding process, while the precision injection molding process can further ensure the flatness of the disc surface and the accuracy of the data track.
In the production and processing of discs, the production environment must also be strictly controlled to avoid dust, oil and other pollutants from damaging the disc surface. Usually, the production workshop will be equipped with an efficient air purification system and cleaning equipment to ensure the cleanliness of the production environment.
In addition, with the continuous development of technology, more and more advanced manufacturing technologies and equipment are being applied to the production and processing of discs. For example, ultra-precision processing technology, laser processing technology, etc., these technologies can further improve the surface finish and dimensional accuracy of discs and meet higher-level data storage needs.
In summary, in the precision production and processing of discs, ensuring extremely high surface finish and dimensional accuracy is the key to achieving high-quality discs. By adopting advanced polishing technology, mold forming technology, precision injection molding process and strictly controlling the production environment, the production quality and performance of discs can be effectively improved to meet people's increasingly high requirements for data storage media.
