TSXR-C 2+2
High precision pull-down chuck Ø 265 - 315 mm
■ Active pull-down ■ 2+2 jaws ■ Tongue & groove
Pull down chuck 4 jaws 2+2
Application/customer benefits • Self-centering clamping of irregular pieces on four sides even on two different axial levels. For example: 1st operation of the differential case turning • Machining of parts where the concentricity between the turned diameters and the square / rectangular / irregular profile on which the chuck clamps is very accurate • Centering the pieces with the two self-centering movements of the two pairs of jaws • Actuation only with double piston cylinders of the series DCE • Clamping of workpieces with highest demand for parallelism • Highest productivity with long maintenance intervals • Constant grip force and long lifetime ensure constant quality of workpieces Technical features
• 2+2 jaw chuck with 2 independent self-centering jaw drives, thanks to the 2 internal wedges • Jaw 1 + 3: TX jaws very rigid and accurate • Jaw 2 + 4: Can be rigid (TSXR-C) or floating depending on the customer application • Active pull-down
• Centrifugal force compensation • TONGUE & GROOVE master jaws • Optional central hole for air or coolant • Permanent grease lubrication • proofline® chucks = fully sealed - low maintenance

2+2 jaw chuck Mounting bolts
Principle of function: ■ 1 pre-clamping - 2 active pull-down - 3 clamping ■ For O.D. and I.D. clamping.
■ TSX-C: chuck operated with a DCE cylinder with central bore for air sensing and / or coolant flush.
TSX-C: High resistance to the radial torque, ideal for turning and milling application and guarantee of high precision, durability and constant process results.
