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-D: Master jaws with INCH SERRATION (1/16"x 90°) BP-M: Master jaws with METRIC SERRATION (1.5 mm x 60°) (suitable for japanese jaws) Technical features • Constant gripping force with permanent grease lubrication • Large through hole compatible with the standard machines • Chuck body and internal parts case hardened • Proofline®chucks = fully sealed - low maintenance seale maint Standard equipment 3 jaw chuck 1 set T-nuts and bolts 1 set soft top jaws Mounting bolts Ordering example 3 jaw chuck BP-D 220 / Z170 or 3 jaw chuck BP-M 220 / A6 Actual gripping force diagrams 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%
