Manual clamping unit QCS

machining

HSK has already become a standard interface in rotating processes. To make it possible to use it in static operations in turning machines, OTT-JAKOB – inspired after joining the HSK-T working group – developed the QCS manual clamping unit. The quick-change clamping system (QCS), designed especially for manual quick changes with HSK holders, is compatible with all HSK standards (A, B, E, F, T). It is not necessary to change the turret. The generation of force through Archimedean spirals produces a self-locking effect. Easy to operate with a spanner, it guarantees quick and easy tool changes. QCS can be used with and without coolant. It is particularly effective if combined with an HSK-T tool and an HSK-T holder. This is due to the high positioning accuracy resulting from the limited tolerance of the HSK-T driver grooves.
