CBN-A80M – Metal Bond System

Name: CBN-A80M - Metal Bond System
Brand: Crownkyn

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

CBN-A80M is a high-strength, high-toughness monocrystalline CBN micron powder with selected crystal morphology, controlled particle size distribution, and high surface cleanliness. Developed for vitrified- and metal-bond grinding tools, it supports precision grinding of hardened ferrous materials and is also suitable for selected PCBN and polycrystalline CBN compact manufacturing applications.

Features

High-Strength CBN Crystals: Selected monocrystalline particles provide grain integrity for demanding precision grinding applications.
High Toughness: Supports particle retention and controlled abrasive wear under demanding grinding conditions.
Selected Crystal Morphology: Defined cutting edges support effective material removal and consistent abrasive action.
Controlled Particle Size Distribution: Classified micron grades support consistent abrasive sizing for grinding tools and selected PCBN processing requirements.
High Surface Cleanliness: Supports bond compatibility and material selection for abrasive tools and PCBN manufacturing.
Dual Application Direction: Suitable for selected vitrified- and metal-bond CBN tools and polycrystalline CBN compact production.
