CBN（立方晶窒化ホウ素）

Welcome to SinoDiam’s CBN (Cubic Boron Nitride) collection—four specialized grades engineered to solve diverse ferrous metal grinding challenges. From resin bond tools for basic steel finishing to high-temperature-resistant options for hardened alloys, every grade in this collection is crafted with strict quality control, precise particle sizing (50/60–325/400 mesh), and bond compatibility tailored to global tool manufacturers and machining shops. Designed for efficiency, durability, and versatility, our CBN collection eliminates the hassle of sourcing multiple abrasives: whether you need self-sharpening grit for resin wheels, multi-bond compatibility for mixed workflows, fine-finish friable particles, or extreme-condition performance for high-speed grinding—we have a grade built for your needs. Each product meets international quality standards, ensuring consistent results across automotive, aerospace, tool manufacturing, and general machining applications. What Makes Our CBN Collection Stand Out? • Ferrous Metal Expertise: All grades are optimized for processing ferrous metals and alloys (carbon steel, stainless steel, hardened steel, cast iron)—materials where CBN outperforms traditional diamond abrasives. • Precise Particle Control: Every grade offers 50/60–325/400 mesh sizes, with strict size tolerance (±5%) to ensure uniform distribution in bonds and consistent grinding results. • Bond-Specific Design: From resin-only compatibility to multi-bond versatility (vitrified/metal/electroplated), each grade is engineered to maximize adhesion and tool life in its target bond system.
