APL-RR
High precision power chuck Ø 215 - 400 mm
■ Quick jaw change ■ proofline ® chucks = fully sealed - low maintenance
LONG STROKE
Application • Sealed chuck with quick jaws change system • Easy coupling and uncoupling with spring loaded pin
• For mid to large batch production • Safety against accidental release • Suitable for manual and/or robotic use • Fully sealed, ideal for dry machining of castings and forgings, or if high pressure coolant is used • Extra long jaw stroke of clamping and wide range of workpieces clamping with the same serie of jaws • Available sizes Ø 215-400 - ready for robotized change • Semifinished pallet and top jaws kit Technical features • EXTRA long jaw stroke • Costant gripping force with permanent grease lubrication • Center bore for coolant and/or air • Chuck body and internal parts case hardened • proofline ® chucks = fully sealed - low maintenance
