Product Overview:

When machining hardened steels and tough ferrous alloys, conventional abrasives suffer from high wear rates, frequent dressing downtime, and potential thermal damage. Our upgraded Metal-Bonded 1A1 (Plain) and 12A2 (Dish/Cup) CBN Grinding Wheels are manufactured using high-purity premium CBN crystals consolidated within a specialized bronze/metal sintered matrix. This delivers exceptional thermal conductivity, superior profile retention, and unmatched tool longevity under high-load conditions.

Key Performance Advantages:

• Exceptional Wear Resistance & Profile Retention: The robust metal bond firmly holds CBN grains, preventing premature shedding and ensuring tight geometric tolerance across massive production runs.

• Superior Thermal Management: High thermal conductivity rapidly dissipates grinding heat from the contact zone, eliminating work-piece thermal cracks, burning, and micro-structural annealing.

• Optimized Cost Efficiency: Extended wheel lifespan and low wear rates drastically reduce dressing frequencies, wheel changes, and total cost per finished unit.

Application Profiles:

• 1A1 (Plain Wheel): Designed with a peripheral grinding layer for high rigidity and stability. Ideal for OD/ID cylindrical grinding, precision surface profile grinding, and deep slotting of hardened components.

• 12A2 (Dish Wheel): Features an angled face layer tailored for clearance angle grinding and sharpening. Perfect for rake and clearance grinding of HSS and Carbide end mills, reamers, face cutters, and woodworking saws.

Target Workpiece Materials:

Specifically formulated for high-hardness ferrous metals ($text{HRC } 45text{--}65$):

• High-Speed Steel (HSS), Tool Steels, Die Steels

• Bearing Steels, Gear Steels, Nitrided Surface Components

• Iron-based Powder Metallurgy & Nickel/Cobalt Heat-Resistant Alloys
