Mini, most used worldwide reference system for electrodes

  • Electrode holder system is still the Mini system.

  • The product program ensures exact mounting of the electrode holders in hydraulic chucks.

  • The Mini system is a “Reverse Reference System”, in which the chuck adapts itself to the electrode holder, which is why all electrode holders must be exactly alike – in diameter, roundness and straightness – to meet the accuracy requirements.

  • This accuracy is achieved thanks to the two annular chambers of the hydraulic system, which expand uniformly and provide symmetrical locking against the fixed Z-reference with angular  location.

Features:

  • Clamping force 4.000N
  • Repeatability <0.002mm
  • High accuracy
  • Flushing pressure 75 bar
