Diamond and CBN Honing Stones for Sunnen Honing Machines

Product Description

Product Overview

Diamond and CBN (Cubic Boron Nitride) honing stones are precision abrasives designed for use with Sunnen honing machines, which are renowned for their accuracy in bore finishing. These stones leverage the exceptional hardness of diamond (ideal for carbides, ceramics, and non-ferrous materials) and CBN (optimized for hardened steels and ferrous alloys) to deliver superior surface finishes, tight tolerances, and extended tool life. They are critical applications in automotive, aerospace, and manufacturing industries, where precision bore geometry and surface integrity are paramount.

Company Profile

Compatibility with Sunnen Machines

These honing stones are designed for use with Sunnen honing systems, including:

• Vertical Honing Machines (e.g., SV-15): For large or heavy parts (bore range: 19-203 mm) .

• Horizontal Honing Machines (e.g., AH-300 D/E): For high-volume production (bore range: 5.92-50.8 mm) .

• CNC Honing Systems: For automated, precision bore correction .

• Tooling Systems:

  • DH Series: Multi-stone tools for coarse and fine honing in a single pass .

  • CK/CV Series: Replaceable stones for models like CK10, CV616 .

 

Applications

• Automotive:

  • Engine cylinder honing (e.g., R28 DM05 stones for engine blocks) .

  • Transmission components and fuel injector nozzles .

• Aerospace:

  • Hydraulic actuator cylinders and turbine blade cooling holes .

• Industrial:

  • Hydraulic tube polishing (e.g., Sunnen stones for hydraulic pipes) .

  • Precision mold and die finishing .

 

Operational Guidelines

• Machine Setup:

  • Ensure compatibility with Sunnen tool holders (e.g., mandrels for BL10 tools) .

• Coolant Use:

  • Apply Sunnen-recommended honing fluids to minimize heat and extend stone life .

• Dressing/Maintenance:

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

• Speed Parameters:

  • Operate within Sunnen machine limits (e.g., 90-350 RPM for SV-15) .

Key Features and Benefits

• Exceptional Durability:

  • Diamond and CBN abrasives offer 20-50x longer lifespan than conventional stones, reducing downtime and replacement costs .

  • Metal bond matrices (common in Sunnen-compatible stones) provide superior abrasive retention and wear resistance .

• Precision Performance:

  • Achieve surface finishes up to Ra ≤ 0.05 µm and tolerances within ±0.001 mm .

  • Uniform abrasive distribution ensures consistent material removal and minimal bore taper .

• Thermal Stability:

  • Withstand high temperatures without degradation, minimizing workpiece thermal damage (e.g., burning or micro-cracks) .

• Versatility:

  • Available in grit sizes from #80 to #1000 (coarse to fine) for roughing, finishing, and ultra-precision honing .

  • Compatible with various Sunnen tooling systems (e.g., CK, CV, DH series) .

• Customization:

  • OEM/ODM support allows for tailored dimensions, grits, and bonds to meet specific application needs.
