Lever chuck Ø 215 - 365 mm
Application/customer benefits • Self centering clamping of flange or shaft type workpieces where the reference is not a center but the O.D. of the workpiece • The through-hole of the chuck allows to swallow the workpiece if needed • Due to its high rigidity against torsion the chuck can be used for turning as well as for milling ■ Self centering clamping ■ Large through-hole ■ proofline ® chucks = fully sealed - low maintenance
Self centering clamping TONGUE & GROOVE
Technical features • For O.D. clamping only • Large through-hole • Tongue & groove base jaws • Pull-down to axial datum Standard equipment
• Permanent grease lubrication • Rigid design against torsion • proofline® chucks = fully sealed - low maintenance Ordering example 3-jaw chuck FRS 285 Z 220
