■ LARGE THROUGH HOLE ■ 3 jaws Tongue & groove ■ proofline® chucks = fully sealed - low maintenance Application/customer benefits • General use on standard lathes due to the through hole, but with advantage of minimum maintenance and use also in extreme environments • Longer life at high precision due to less wear • Fully sealed, ideal for dry machining of castings and forgings or if high pressure coolant is used BP-C: Tongue & groove master jaws (American Standard) Technical features • Constant gripping force with permanent grease lubrication • Large through hole compatible with the standard machines • 3 jaw version available in all diameters • Proofline®chucks= fully sealed - low maintenance Standard equipment Ordering example 3 jaw chuck 3 jaw chuck BP-C 220/Z170 Mounting bolts The data in the diagrams refer to 3-jaw-chucks, newly maintained according to their service manuals using SMW-AUTOBLOK K67 grease. The static and dynamic gripping forces have been measured using standard soft top jaws, placed in a position not exceeding the outer diameter of the chuck. A Safety advice/danger of damage: When using taller/heavier jaws and/or clamping on a bigger diameter reduce draw pull/rotating speed accordingly. SMW-AUTOBLOK Type * For internal clamping reduce the draw pull by 30 %.
