Advantages and Applications of Magnetic Resin Diamond Grinding and Polishing Discs
2026-02-24 17:30In precision manufacturing, stone processing, and surface treatment of hard and brittle materials, selecting the right grinding and polishing tools is crucial for improving processing efficiency and product quality. As the demand for high hardness materials and fine surface treatments increases, traditional grinding methods can no longer meet the high-efficiency and high-quality requirements.
Magnetic resin diamond grinding and polishing disc offer a new solution, combining efficient grinding with fine polishing for precision processing.
Construction and Features of Magnetic Resin Diamond Grinding and Polishing Discs.
These discs are made from a resin matrix combined with diamond abrasives, featuring a metal magnetic backing. Diamond, one of the hardest materials, enhances the disc's wear resistance and grinding strength, allowing it to easily handle high-hardness materials. The resin matrix ensures that the disc surface maintains flexibility and uniformity, improving surface smoothness and reducing scratches during processing.
Our magnetic resin diamond grinding and polishing disc can be tightly attached to the grinding equipment surface, saving installation time and improving ease of use. The magnetic backing also offers strong resistance to deformation and high-temperature performance, ensuring stable performance even under prolonged heavy-duty operation.

Efficient Grinding and Precise Polishing: Wide Range of Applications.
These discs are versatile and suitable for processing high-hardness and brittle materials, such as crystal materials, ceramics, hard alloys, optical glass, gemstones, and diamond crystals. These materials often have high hardness and brittleness, requiring grinding tools with significant power to quickly remove the material surface and delicate polishing to achieve a smooth finish.
The discs are available in a wide range of grit sizes, from 80# to 2000#, covering everything from rough grinding to fine polishing. Customers can select the appropriate grit for different stages of surface treatment to meet their specific processing needs.
No Liquid Abrasives Needed, Reducing Processing Costs.
Traditional grinding processes typically require liquid abrasives as an essential auxiliary material. However, liquid abrasives not only increase costs but also complicate cleaning and handling. Magnetic resin diamond grinding and polishing disc can operate without the need for liquid abrasives. The diamond abrasives come into direct contact with the material surface for cutting, reducing the consumption of grinding media and lowering cleaning and maintenance costs, ultimately improving overall processing efficiency.
Without the need for liquid abrasives, there’s also a reduction in environmental pollution and internal cleaning efforts, making these discs ideal for companies focused on sustainability.
Our magnetic resin diamond grinding and polishing disc deliver excellent performance and are compatible with various equipment and processing requirements. They can be used with our UNIPOL series grinding and polishing machines to offer stable and efficient grinding solutions. We also provide a variety of disc diameters, including Ø150mm, Ø200mm, Ø250mm, Ø300mm, Ø320mm, and Ø381mm, allowing users to select the right size and grit to achieve optimal processing results.
