High-Quality Diamond Stones for Sunnen Honing Mandrels - Direct Supply

Product Description

Product Overview

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.

Key Features

1. 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 .

2. 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 .

3. 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 .

4. 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 .

5. 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 .

Compatibility with Sunnen Machines

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 .

 

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 .

 

Operational Guidelines

1. Machine Setup:

   • Ensure mandrels (e.g., BL10 tools) are securely mounted and aligned .

2. Coolant Recommendations:

   • Use Sunnen honing oils or high-pressure coolants for heat dissipation and chip evacuation .

3. Dressing & Maintenance:

   • CBN stones typically require no dressing, but periodic cleaning prevents abrasive loading .

4. Speed Parameters:

   • Operate within Sunnen machine limits (e.g., 200-2,500 RPM for MBC-1800) .
