  1. Nondressable cylindrical and globoidal CBN grinding worm technology is designed for hard finishing gears.

  2. Design:
    Hardened steel body with ground base profile and a single layer of CBN crystals galvanically plated and nickel bonded, with varying grit size depending on the grinding application.

  3. Profile forms determined by gear data, i.e. information from a workpiece drawing, a mathematical description, or a coordinate representation.

  4. The form accuracy of all KAPP CBN worms is guaranteed throughout the life of each CBN plating. The achievable form tolerances correspond to respective application.

  5. KAPP CBN worms provide optimum cutting performance and wear resistance throughout the life of each CBN plating and a minimum number of parts per plating can be calculated.

  6. Re-plated wheel base bodies retain original specifications and performance characteristics.

  7. The stock removal can be divided into rough and finish grinding. Grinding from the solid is also possible.

  8. Excellent wheel location accuracy, meaning diameter and face runout errors are minimized by mounting the CBN profile grinding wheel directly on a cylindrical grinding spindle pilot.

  9. Worm dimensions:
    Diameter range 160...200 mm
    Profile width up to      160 mm
