Brazed diamond grinding discs stand out as a prime choice for high - intensity industrial grinding scenarios. Their core lies in the brazing technology, where diamonds are firmly affixed to the base matrix. This technology allows for an average diamond concentration of 75 - 80%, ensuring sharpness and durability. In contrast to traditional electroplated diamond discs with a diamond concentration of around 60%, brazed discs demonstrate superior grinding performance.
The brazing process creates a robust chemical bond between the diamond and the base material. Tests show that the bond strength can reach up to 200MPa, which provides excellent resistance to high - speed impacts and large - load grinding operations. This means the disc can maintain its integrity during long - term and intensive use, reducing the need for frequent replacements.
These grinding discs are highly versatile, suitable for a wide range of hard materials. When grinding gray iron, they can achieve a material removal rate of up to 100 cubic centimeters per minute, significantly improving production efficiency. For ductile iron, the grinding surface roughness can be controlled within Ra 0.8 - 1.6μm, ensuring high - quality finishing. In the case of stainless steel, the heat - generated during grinding is effectively dissipated, preventing material discoloration and deformation.
The manufacturing process of brazed diamond grinding discs is highly controlled, ensuring consistent quality across batches. This consistency means that users can expect the same high - performance grinding results every time they use a new disc, reducing the uncertainty in the production process.
A well - known automotive parts manufacturer switched to using brazed diamond grinding discs for the grinding of engine blocks. After a three - month trial, they reported a 30% increase in production efficiency and a 40% reduction in tool replacement frequency. Another user in the aerospace industry mentioned that the use of these discs improved the surface quality of their components, meeting the strict quality requirements of the industry.
Brazed diamond grinding discs come in a variety of sizes, typically ranging from 100mm to 300mm in diameter, catering to different grinding equipment and work requirements. Smaller - sized discs are suitable for detailed and precision grinding, while larger - sized discs are more efficient for large - area grinding.
For specific industrial needs, customization services are available. Customers can request custom - made discs with special diamond grit sizes, segment shapes, and bond strengths. This ensures that the grinding disc is perfectly matched to their unique production processes, achieving maximum production efficiency and tool life.
To achieve the best results, it is recommended to use the appropriate coolant during grinding operations. This helps to reduce heat generation, extend the tool life, and improve the surface quality of the workpiece. Additionally, regular inspection of the grinding disc for wear and damage is crucial to ensure safe and efficient operation.
