Technical Field

[0001] The invention relates to the technical field of grinding disc correction, in particular to a grinding disc flatness correction device. Background Art

[0002] A grinding disc is a processing tool that uses the friction between the abrasive and the workpiece surface to remove the workpiece surface material. Its main purpose is to improve the flatness, parallelism and finish of the workpiece surface through the grinding and polishing process to meet specific technical requirements and usage standards. Grinding discs are usually made of high-hardness materials, such as diamond, alumina, etc., to ensure that they are not easily worn during the grinding process. Different types of grinding discs are suitable for different materials and processing requirements. They can be selected and replaced as needed. The design of the grinding disc can improve grinding efficiency, reduce processing time and cost, and ensure processing quality.

[0003] Among them, diamond grinding discs are composed of diamond abrasive grains and a disc body, and are suitable for precision grinding and polishing of high-hardness materials. Cast iron grinding discs are made of high-quality gray cast iron, have good wear resistance and thermal stability, and are suitable for grinding various metal and non-metal materials. There are also ceramic grinding discs with high hardness and good wear resistance, which are suitable for special applications that require a cleaner grinding process. Grinding discs are widely used in the semiconductor industry, metal processing, optical manufacturing, precision machinery and other fields, in which grinding discs are used to achieve high-precision surface treatment and processing.
