CBN-B15M – Resin Bond Micron CBN Powder

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

CBN-B15M is a black monocrystalline CBN micron powder produced from synthetic CBN through controlled crushing and classification. Its angular particle morphology and controlled size distribution support efficient, consistent cutting in resin-bond grinding wheels, honing tools and fine abrasives for hardened steels and other ferrous materials.

Features

Monocrystalline CBN Abrasive: Selected single-crystal CBN particles provide effective cutting action in precision grinding.
Angular Particle Morphology: Defined cutting edges support controlled material removal and surface finishing.
Selected Fracture Characteristics: Supports abrasive cutting activity in resin-bond grinding applications.
Controlled Particle Size Distribution: Classified micron grades support consistent abrasive sizing and surface quality.
Resin-Bond Compatibility: Developed for resin-bond CBN wheels and precision abrasive tools.
