TSX-C: High resistance to the radial torque, ideal for turning and milling application and guarantee of high precision, durability and constant process results. * The above maximum speed is allowed with standard weight / height top jaws and applying the full draw pull only. For more information please contact SMW-AUTOBLOK. ** For internal clamping reduce the draw pull by 30%. SMW-AUTOBLOK Type Number of jaws Angular jaw stroke U° (TX) deg.

No. TSXR-C (center mounting) ■ Active pull-down ■ 2+2 jaws ■ Tongue & groove fully sealed – low maintenance proo ine® series 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 Standard equipment Ordering example 2+2 jaw chuck Mounting bolts 2+2 jaw chuck TSXR-C 265 BIS Specials Website: www.bisspecials.com Email: info@bisspecials.com Tel: (0031) 0313 482566 Website: www.bisspecials.com Email: info@bisspecials.com Tel: (0031) 0313 482566
