CBN-B15 – Balanced Resin & Vitrified CBN Grit

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

CBN-B15 is a black monocrystalline CBN grit developed for resin and vitrified bond systems requiring a balance of cutting efficiency, abrasive stability and self-sharpening. Its irregular particle morphology and medium crystal strength provide controlled fracture during grinding, making it suitable for precision processing of hardened steels and ferrous components.

Features

Irregular Monocrystalline Morphology: Provides active cutting edges for efficient grinding.
Medium Crystal Strength: Balances grain stability with controlled abrasive breakdown.
Controlled Self-Sharpening: Supports progressive edge renewal during precision grinding.
Balanced Bond Compatibility: Suitable for resin and vitrified CBN grinding systems.
