TEF-C TER-C
High precision pull-down chuck 2+2+2 equalising Ø 260 - 850 mm
■ Active pull-down ■ Tongue & groove ■ 6 jaws 2+2+2
Self centering Floating jaws
Self centering Rigid jaws
Application/customer benefits • Clamping of thin walled workpieces • Suitable for OP 10 or unique clamping applications • Low radial deformation with 2+2+2 clamping • Constant grip force and long lifetime ensure constant quality of workpieces • Low profile, ideal for machines with limited Z axis stroke Technical features • 6-jaw design • Active pull-down • Floating base jaws for 12 point contact
• Central bore for coolant and / or air • Permanent grease lubrication • proofline ® chucks = fully sealed - low maintenance
• Centrifugal force compensation • TONGUE & GROOVE base jaws Standard equipment
