Fast changeover, fast payback: The original quick jaw change power chuck
KNCS ® -N
Easy lubrication even on vertical machines with 3 radial built-in grease fittings
Extra long, symmetrical jaw guides. Ideal for O.D. or I.D. clamping
Minimal set-up times Jaw change in less than 1 minute
High repeatability when changing jaws
No reboring of already machined jaws necessary, because runout < 0.02 mm (KNCS-N 210)
Unique wedge bar drive for high speed . Minimum loss in gripping force because of tangentially supported wedge bars. Minimum increase of gripping force (hysteresis) after quick spindle stop. High efficiency of the wedge bar drive ensures highest
concentricity and repeatability. Suitable for high-low clamping
Flexibility jaws can be radially adjusted and are reversible = less jaw sets
Direct mounting
Original SMW-AUTOBLOK quick jaw change . Jaw change accuracy with patented jaw safety interlock
