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.
