Product Characteristics
At Boreas, our BRM-DK polycrystalline diamond products undergo a specialized surface treatment process. This innovative method induces chemical reactions on the surface of the diamond particles, increasing their roughness and enhancing the grip between the diamond particles and the bonding agents. This results in improved self-sharpening properties and cutting power of the diamond, while effectively preventing surface scratches on workpieces during cutting and polishing, thereby enhancing polishing accuracy.

Superior Properties of Boreas BRM-DK Polycrystalline Diamond Micron powder
Boreas BRM-DK micron powder is characterized by excellent thermal stability, high hardness, superior wear resistance, and strong chemical stability. As modern industry and technology continue to advance, BRM-DK is increasingly used in various fields due to its exceptional mechanical, thermal, chemical, acoustic, optical, and electrical properties.
1.High Hardness and Wear Resistance:With a hardness of approximately 10,000 HV, BRM-DK is the hardest artificial material available, significantly surpassing the hardness of carbide and engineering ceramics. Its isotropic structure ensures remarkable wear resistance.
2.Low Friction Coefficient:BRM-DK exhibits a much lower friction coefficient with certain non-ferrous metals compared to other materials, roughly half that of carbide. This reduces deformation and cutting forces, prevents the formation of built-up edges, and lowers surface roughness during machining.
3.High Thermal Conductivity:the thermal conductivity of BRM-DK is superior to that of silver and copper, and significantly higher than conventional carbides. This facilitates the rapid dissipation of heat during cutting, maintaining lower cutting temperatures.
Precision Applications of Boreas BRM-DK
Grinding: Diamond wheels, ELTD mirror grinding, EDM grinding
Diamond wheel lapping, high-speed steel disk lapping, abrasive lapping
Other Machining: EDM wire cutting, laser processing, chemical machining, ultrasonic machining
Future Trends in BRM-DK Development
1.Larger Specifications:Polycrystalline diamond are being developed in increasingly larger sizes to meet diverse industrial needs.
2.Grain Refinement and Quality Optimization:Early BRM-DK products utilized diamond micron powder around 50μm; advancements now allow the use of 2μm or even sub-0.5μm particles, enhancing the precision of BRM-DK tools and wire drawing dies, rivaling single crystal diamond.
3.Increased Wear Resistance:As a key indicator of quality, the wear resistance of BRM-DK has seen significant improvements through years of research and production, resulting in higher wear ratios.
4.Diverse Shapes and Structures:Beyond the traditional flat and cylindrical forms, advancements in size and processing technologies (like EDM and laser cutting) have led to a variety of shapes including triangular, chevron, gable, spherical, and curved surfaces. To cater to specific cutting tool requirements, new forms such as encapsulated, sandwich, and scroll-shaped BRM-DK products have emerged.
At Boreas, we are committed to pushing the boundaries of BRM-DK technology, ensuring our products meet the highest standards of precision and performance. Our dedication to innovation and quality makes Boreas the trusted choice for advanced grinding, polishing, and cutting solutions.
