Application/customer benefits • Clamping of large parts • Self centering clamping of workpieces that need to be centered by the jaws • Compensating clamping of shafts held between centers or centered by other means like collet, mandrel or self centering chucks IND-CP Ø 500-800: Master jaws with INCH SERRATION (3/32’’ x 90º) IND-CP Ø 1000-1250: Master jaws with MODULE 2 TONGUE & GROOVE master jaws on request Technical features • Gripping force transmission via wedge hook • Sealed against swarf and chips • Conversion self centering / compensating with an easy rotation of internal ring • Rotation of the conversion ring with chuck mounted on machine Standard equipment 3-jaw chuck / 1 set T-nuts with screws 1 set soft top jaws with bolts Center point on request Ordering example 3-jaw chuck IND-CP 630 / A15
Actual gripping force diagram
The data in the diagram 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.
