What is QDES.60

QDES.60 is a system of rapid centering and clamping of the die to the rotary shaft. It is realized by means of four fixed centering jaws that fix the position of the die axis with the axis of the rotary shaft and the front plane of the rotary shaft perpendicular to the axis of the rotating shaft.


The die is released from the jaws through the hydraulic pump in a few seconds, after unscrewing only a dozen or so fastening screws.


QDES.60 allows to disassemble the hot die, while maintaining appropriate security measures, without losing time often associated with the need to at least partially cool it down.
