BALDIA COMPOSITE DC

When the highest part quality is required, together with tool design and geometry, edge preparation and interface engineering, especially tightest tolerances in tool diameter and coating thickness must be ensured to achieve best results.

BALDIA® COMPOSITE DC enables the best possible finishing accuracy through consistently high tool performance with tight bore tolerances when machining carbon fibre (CFRP), glass fibre (GFRP), stack material and aluminium alloys (Si > 12%).

By choosing BALDIA® COMPOSITE DC, you also profit from an enhanced quality control and a special chemical pre-treatment of the substrate.

  • Advantages

    Advantages

    • Highest abrasive wear resistance
    • Less sticking of metallic stack materials (e.g. aluminium and titanium) to the tool
    • Allows optimum process reliability and perfect hole quality
    • On-demand adjustment of diameter tolerance on drills with 100% control
    • Sharpest cutting edges due to non-mechanical pre-treatment
    • Excellent quality due to improved quality control
