CBN Abrasive Sanding Belt

CBN (cubic boron nitride) is a highly sought-after abrasive grain due to its exceptional hardness and chemical inertness, second only to diamond. Our new CBN abrasives are specially designed to tackle the toughest materials, including hardened steel (>55 HRC), ceramic materials, high-speed steel, nickel-based superalloys, and chilled castings.One of the key features of our CBN abrasive belts is their flexibility, thanks to the use of patented aramid fibers as a support material. Aramid fibers, also known as Kevlar, are renowned for their high strength, elongation, and vibration-dampening properties. To further enhance the durability and performance of our CBN abrasives, the support material is applied with a formfitting copper layer.The CBN crystals are then bonded to the abrasive belt using a galvanic process that involves a nickel-based alloy. Depending on the application, the CBN crystals can be arranged in a regular intermittent pattern or with no spacing, covering the entire surface of the belt. This ensures maximum cutting efficiency and a longer service life for the abrasive belt.Whether you're working with tough materials like hardened steel or looking for a high-performance abrasive solution for your manufacturing process, our CBN abrasives are the perfect choice. With their exceptional hardness, chemical inertness, and flexible design, they offer unparalleled cutting power and durability.
