TSBF-CP TSBR-CP Compensating Floating jaws Compensating Rigid jaws
Compensating pull-down chuck Ø 220 - 330 mm
■ Active pull-down ■ Tongue & groove ■ Large through-hole ■ 3 jaws
Application/customer benefits • Clamping of shafts or chuck parts where the reference is not the O.D. but a center or a centering diameter • A center point or a centering insert will center the workpieces and the jaws will clamp compensating and actively pull the workpiece down to the datum • Through-hole to insert long workpieces or for special clamping applications TSBF-CP: Compensating clamping with active pull down and floating base jaws TSBR-CP: Compensating clamping with active pull down and rigid base jaws Technical features • Active pull-down • TONGUE & GROOVE base jaws • Compensating clamping • Permanent grease lubrication • Centrifugal force compensation • proofline ® chucks = • Large through-hole fully sealed - low maintenance Standard equipment Ordering example 3-jaw chuck 3-jaw chuck TSBF-CP 220 / A6 Mounting bolts or 3-jaw chuck TSBR-CP 330 / Z300

■ The workpiece is actively pulled down to the center point. The tailstock just supplies the necessary force to support the workpiece. The result is an exact cylindrical and straight workpiece.
Principle of function: ■ 1 compensating pre-clamping - 2 active pull-down - 3 clamping

Non active pull down compensating chuck
■ The workpiece is lifted by the jaws from the center point. When a higher tailstock force is applied for compensation, the workpiece will be bent. Technical data
