KNCS®-N Fast changeover, fast payback: The original quick jaw change power chuck 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 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 Original SMW-AUTOBLOK quick jaw change. Jaw change accuracy with patented jaw safety interlock 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) Flexibility jaws can be radially adjusted and are reversible = less jaw sets Jaws radially adjustable Jaws 180° reversed Direct mounting Recess and bolt circle to DIN 55026 Vertical application Version for vertical application with cover and drain holes for coolant available. If serration is not fully engaged – jaw safety interlock is active Profitability Example set-up times / costs Conventional chuck KNCS®-N Jaw change 10 Min. 1 Min. Reboring of jaws 20 Min. 0 Min.
