Product Description

32MM 4 Stone Honing Head for Valve Sleeve Bore Finishing
 

Product Description

Multi-stone honing heads (also known as MMT-type mandrels) are advanced tooling solutions designed for use on a wide range of high-production horizontal honing machines, including Sunnen SH, ML series, as well as machines from other major manufacturers. These tools are ideal for internal bore finishing across a variety of metals, especially where tight tolerances and consistent geometry are required.

Applicable Bore Sizes

Standard configurations are available for bore diameters from 15 mm to 80 mm. 

Features and Benefits

Key Advantages

• Up to 30% Lower Per-Part Honing Costs
  Compared to conventional honing tools, multi-stone mandrels deliver improved efficiency and longer service life, significantly reducing overall production costs.

• High-Quality Superabrasives
  Available with precision-graded metal-bonded CBN or diamond stones, tailored to specific material types and finishing requirements.

• Excellent Bore Geometry
  Multi-stone configuration ensures uniform pressure and alignment, producing superior roundness, straightness, and surface finish - even on heat-treated or distorted parts.

• Precision Engineering
  Each honing tool is precision-machined from high-strength steel to guarantee perfect alignment of the abrasive stones, optimizing tool life and dimensional control.

• Reduced Cycle Times
  Higher material removal rates and stable cutting performance allow for faster honing cycles, boosting productivity.

• Quick-Change Options Available
  For faster mandrel swaps in high-volume production environments.
