Supplier's note

  1. Technical Breakthroughs:

    • PCD Coating: Enables 20% faster machining speeds in aluminum compared to traditional CVD coatings.
    • CBN Layer: Achieves triple the wear resistance of standard tungsten carbide tools in cast iron.
    • Hybrid Coating Design: Combines PCD’s thermal stability with CBN’s hardness for dual-material compatibility.

  2. Version Selection Guide:

    • Base Model: Ideal for small workshops or low-volume production of standard cast iron components.
    • Advanced Model: Recommended for automotive manufacturers needing mid-tier performance in mixed cast iron/aluminum applications.
    • Pro Model: Best suited for high-volume engine production lines requiring extreme durability (e.g., Formula 1 engine blocks). With its 1,950HV abrasion resistance, the Pro version ensures minimal tool changes and maintains precision even in abrasive environments.
