WS 4.5500 Tower Workholding Systems SCT clamping against the fixed jaw, mechanically or hydraulically operated jaw widths 80 and 120 mm, with 3 or 4 clamping sides Advantages ● 2 sizes for optimum design to the machining centre ● Clamping of 3 or 4 workpieces with standard jaws ● Mechanical or hydraulic build up of the clamping force ● Easy and safe operation ● Large jaw openings and high flexibility due to extensive range of clamping jaws ● Highest stability by design as a monoblock ● Optimum protection against contamination ● Process-safe application of clamping force, also when using grip jaws Application SCT tower workholding systems are used on horizontal machining centres, in vertical m achining in connection with 4th axis, but also on 5-axis machining centres. The applications range from manually equipped machines to pallet stations and fully automated systems. The stability of the clamping systems and the high retention force due to the use of the special grip reversible jaw with hard metal coating make pre-embossing of the workpieces superfluous.

A torque wrench is used for exact and reproCustomised versions ducible clamping force adjustment. Tower workholding systems SCT can also be delivered as customised versions. For Hydraulically operated example in other lengths, with individual Hydraulically operated versions are single mounting holes or with holes for a zero point acting. Clamping is effected by hydraulic clamping system. p ressure, unclamping by spring force.

Extensive information such as drawings and n CAD models are available on request. Application example Description Tower workholding systems of the SCT series excel by a very compact design. Thanks to the adjusting spindle arranged in the upper part of the housing, deformation in the base during clamping is reduced. All essential components are made of steel.
