Vitrified Bond CBN Grinding Wheel 200mm Standard Diameter for Bearing Steel Precision Grinding Superior Finishing
6A2 Vitrified Bond CBN Grinding Wheel for Bearing Steel Precision Grinding
Designed for high-precision grinding of bearing steel and automotive components, this 6A2 vitrified bond CBN grinding wheel delivers superior surface finish with excellent self-sharpening characteristics. The vitrified bond structure features controlled porosity for optimal coolant flow and efficient chip clearance during continuous grinding operations.
Key Features
- Superior Surface Finish: Fine grit CBN abrasive combined with advanced vitrified bond technology delivers mirror-like surface quality on bearing steel workpieces, achieving Ra 0.1-0.2µm consistently
- Excellent Self-Sharpening: Controlled bond erosion continuously exposes fresh sharp abrasive grains, maintaining consistent cutting action without frequent dressing interruptions
- Eco-Friendly Operation: Vitrified bond formulation requires no toxic chemical additives and is fully compatible with water-based coolant systems, supporting sustainable and pollution-free manufacturing
- High Profile Retention: Rigid vitrified bond structure maintains precise wheel geometry for tight tolerance grinding, ensuring dimensional accuracy across long production runs
