Carbon-ceramic composites (CF/SiC) combine the advantages of carbon materials and ceramic materials, offering excellent high-temperature resistance, wear resistance, lightweight properties, and high mechanical strength. These advanced materials are widely used in aerospace, carbon-ceramic brake discs, high-performance automotive components, and precision industrial applications.
Due to the extreme hardness and abrasive characteristics of CF/SiC materials, conventional abrasives such as CBN, green silicon carbide, and aluminum oxide grinding wheels are not suitable. They suffer from rapid wear, wheel loading, and poor grinding performance. Diamond grinding wheels are the preferred solution for efficient and stable machining of carbon-ceramic composites.
Best for: Precision grinding, face/flat grinding, trimmingAdvantages: No workpiece burning, good toughness, anti‑chipping, excellent self‑sharpeningMachines: Surface grinders, universal tool grinders, profile finishing
