Object candidates of changing and attention

  • Reduce tool replacement time

    Improvement of tool replacement time especially for automatic machines with a small space for tool exchange.

  • 1.5xD

    is now a standard product.

  • Slotting

    We didn't get good result with slotting by using BT30 machine. Slotting is not recomended for this product.
