Resin bond CBN wheels

CBN Resin Bond Wheels – High-Performance Grinding for Hardened Steels & High-Alloy Materials A CBN resin bond wheel is the ideal choice for precision grinding of hardened steels and high-alloy metals where heat control, surface finish, and edge integrity are critical. Resin bond offers a fast, cool-cutting action that preserves the natural sharpness of CBN (cubic boron nitride), making these wheels essential in tool grinding, production machining, and high-accuracy manufacturing environments. 1. Superior Performance on Hardened Steels CBN is the second-hardest abrasive after diamond—but unlike diamond, it does not chemically react with iron, making it the best abrasive for ferrous materials. Use CBN resin bond wheels for grinding: High-speed steel (HSS) M2, M35, M42 cobalt steels D2, A2, S7 tool steels Powder-metal steels Bearing steels (52100) Nickel-based alloys The resin bond matrix enhances performance through controlled breakdown, continually exposing new CBN cutting edges and maintaining aggressive cutting throughout the wheel’s life. 2. Cool-Cutting Grind With Minimal Heat Damage Resin bond provides a natural cushioning effect that: Absorbs grinding forces Generates less friction than metal bond Reduces burning, thermal cracking, and part distortion Protects thin edges and heat-sensitive profiles This makes CBN resin wheels ideal for flute grinding, tool sharpening, form grinding, and fine-finish operations. 3. Superior Surface Finish & Edge Precision CBN resin wheels deliver: Low surface roughness Excellent edge retention Minimal micro-chipping Stable geometry throughout the wheel’s lifespan They are the preferred choice when tight tolerances and high-quality finishes are required on precision tools and hardened components. 4. Predictable Wear & Consistent Cutting Action Resin bond breaks down uniformly, ensuring: Constant cutting sharpness Shorter cycle times Consistent part quality Reduced dressing frequency This makes them ideal for CNC grinding centers, automated lines, and high-volume production cells. 5. Strong Form & Profile Stability Advanced resin systems—such as Braemar “Super Bond”—maintain wheel form under: High grinding pressure Long continuous passes Intricate geometries (1A1, 11V9, 12V9, 6A2, and more) This ensures the precise profile retention required for modern tool manufacturing. 6. Effective in Both Wet and Dry Grinding CBN resin bond wheels are versatile: Wet grinding delivers maximum tool life and best surface finish Dry grinding is suitable for light passes or lower-temperature steels
