CBN-P95 – Polycrystalline CBN Grit

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

CBN-P95 is a polycrystalline CBN abrasive grit developed for demanding grinding applications requiring stable grain wear and continuous self-sharpening. Its polycrystalline structure promotes localized micro-fracturing during grinding, progressively exposing fresh cutting edges while reducing the tendency toward sudden large-scale grain breakdown. This controlled wear behavior supports sustained cutting performance in metal-bond and electroplated CBN tools for hardened steels, high-alloy steels and other difficult-to-machine materials.

Features

Polycrystalline CBN Structure: Fine CBN crystallites create a different wear and fracture behavior from conventional monocrystalline CBN.
Controlled Micro-Fracturing: Localized grain breakdown progressively exposes fresh cutting edges during grinding.
Good Self-Sharpening: Continuous abrasive renewal helps maintain active cutting performance.
Stable Grain Wear: Reduces the tendency toward sudden large-scale grain fracture under demanding grinding loads.
Bonded Tool Compatibility: Suitable for metal-bond, electroplated and selected high-performance CBN grinding tools.
