PCD milling cutters, PCD reamers, PCD engraving tools, PCD non-standard tools, PCBN cutters are better than ordinary carbide cutters; first, the cutter has high hardness. Second, good thermal conductivity. 3. The friction coefficient is small, so the cutting force is small. Fourth, the thermal deformation is small and the machining accuracy is high. Fifth, because of its low affinity with non-ferrous metals and non-metallic materials, it is not easy to cause build-up tumors. This feature has advantages in durability and cutting rate cost-effectiveness in processing wood, graphite, fiber, ceramics, plastics, copper, and aluminum. Incomparable to high-quality alloy tools
