Premium CBN Honing Stones are high-performance abrasives designed specifically for Sunnen honing machines and mandrel systems. Utilizing Cubic Boron Nitride (CBN) abrasives-ideal for hardened ferrous materials like tool steels, cast iron, and alloys-these stones deliver exceptional durability, precision, and surface finish quality. Paired with Sunnen-compatible mandrels, they are engineered for critical applications in automotive, aerospace, and manufacturing industries, where micron-level accuracy and efficiency are paramount .

Exceptional Durability
CBN abrasives offer 20-50x longer lifespan than conventional stones, reducing downtime and replacement costs .
Metal bond matrices (e.g., sintered metal bonds) provide superior abrasive retention and wear resistance, even under high-pressure honing conditions .
Precision Performance
Achieves surface finishes up to Ra ≤ 0.05 µm and tolerances within ±0.001 mm, ensuring optimal bore geometry and minimal taper .
Uniform abrasive distribution guarantees consistent material removal and edge integrity .
Thermal Stability
Withstands high temperatures without bond degradation, minimizing workpiece thermal damage (e.g., burning or micro-cracks) .
Suitable for wet or dry honing applications, with compatibility for Sunnen-recommended coolants .
Customization Flexibility
Available in grit sizes (#80-#1000) for roughing to ultra-fine finishing .
Tailored dimensions (e.g., 4 mm x 6 mm x 100 mm) and shapes (rectangular, curved) to fit Sunnen mandrels (e.g., BL10, CK, CV, DH series) .
OEM/ODM support for branded logos, packaging, and abrasive concentrations .
Efficiency & Cost-Effectiveness
High material removal rates (MRR) reduce cycle times by up to 40% compared to resin-bond alternatives .
Minimal dressing requirements and long service life lower operational costs .

These CBN honing stones are engineered for seamless integration with Sunnen honing systems, including:
Vertical Honing Machines (e.g., SV-15, MBC-1800): For bore diameters of 1.524-165.1 mm and stroke lengths up to 406 mm .
Horizontal Honing Machines (e.g., AH-300 D/E): Ideal for high-volume production with bore ranges of 5.92-50.8 mm .
CNC Honing Systems: Automated precision bore correction with programmable stroking speeds (e.g., 80-310 SPM) and spindle speeds (e.g., 200-2,500 RPM) .
Mandrel Systems:
DH Series: Multi-stone tools for coarse-to-fine honing in a single pass .
CK/CV Series: Replaceable stones for models like CK10, CV616 .
Custom Mandrels: Extended shank designs for deep bores or carbide guides for high-volume applications .
Automotive:
Engine cylinder honing (e.g., R28 DM05 stones for engine blocks) .
Transmission bores and valve guide finishing .
Aerospace:
Hydraulic actuator cylinders and turbine blade cooling holes .
Industrial:
Hydraulic tube polishing (e.g., Sunnen stones for hydraulic pipes) .
Precision mold and die sharpening .
Machine Setup:
Ensure mandrels (e.g., BL10 tools) are securely mounted and aligned .
Coolant Recommendations:
Use Sunnen honing oils or high-pressure coolants for heat dissipation and chip evacuation .
Dressing & Maintenance:
CBN stones typically require no dressing, but periodic cleaning prevents abrasive loading .
Speed Parameters:
Operate within Sunnen machine limits (e.g., 200-2,500 RPM for MBC-1800) .
Proven Compatibility: Optimized for Sunnen's precision machinery ensures reliable performance .
Cost Efficiency: Long life reduces frequent replacements and downtime .
Global Support: Technical assistance and OEM customization available .
Certification: Complies with ISO standards (e.g., ISO9001:2008) .
Samples: Offered by suppliers (e.g., $15-$108.70/stone) .
MOQ: As low as 1 piece for standard stones; 50 pieces for custom logos .
Lead Time: 7-35 days (depends on customization) .
Customization: OEM branding, grit sizes, and dimensions .
