  1. H-24 Replaceable Positioning Block :
    A breakthrough patent design, upgrading your chucks to be part of the asset instead of consumables. If it’s damaged, you can replace it in a short time without affecting the productivity.
  2. When the surface for Z axis is damaged, you may repair by laser welding with the steel. (60 HRC, SUS440 best recommended). Or, you may send it back to us for a repair.
  3. Locking screws : Material SNCM high tension screws, 36~38 HRC. The surface coated with tungsten with more mechanical flexibility.
    Attention : The feature of tungsten coated surface can not work under sulfur environment.
  4. Clamping type mechanism : Patented clamping type design, simple and durable structure which can sustain
    the clamping force more than 4000 kgs.
    Four locking surfaces can bear dramatic vibration and won’t affect the drawbar. Material SUS420, 48~50 HRC.
