IEP-D
High precision 6-jaw chuck 2+2+2 equalising Ø 1000 - 1600 mm ■ Closed center
Application/customer benefits • Clamping of thin walled workpieces ■ Equalising mechanism lockable ■ Centrifugal force compensation
2+2+2 movement MODULE 2 SERRATION
• Low radial deformation with 2+2+2 clamping • Suitable for horizontal and vertical machines Technical features • Adjustable to 6 jaw 2+2+2 or true 6 jaw clamping • Possibility to regulate the equalising stroke from full (for OP10) to very small (for OP20) • Constant gripping force with permanent lubrication
• Master jaws with MODULE 2 SERRATION (pitch 6.28 mm) • Centrifugal force compensation for high spindle speed • proofline ® chucks = fully sealed - low maintenance Standard equipment

Safety advice / danger of damage: When using taller / heavier jaws and / or clamping on a bigger diameter reduce draw pull / rotating speed accordingly.
The data in the diagram refers to 6-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.
