CBN (Cubic Boron Nitride)

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.
