Manufacturers of small and medium-sized batches can operate much more efficiently and significantly reduce workholding costs with SZKU universal top jaws from SCHUNK. This multi-functional jaw from the Lauffen-based specialist for toolholding, workholding and automation combines the essential advantages of two jaw types. The SZKU is as versatile as a stepped jaw and also transmits high torques like a claw jaw.
The universal top jaw covers a large spectrum of clamping ranges and enables both I.D. and O.D. clamping, in addition to bar clamping. Also, workpiece bolts can be used to vary the clamping depth and the universal jaw is ideal even for very low clamping depths. The user can therefore securely hold diverse workpieces with only one jaw set. That significantly reduces the requirement for different claw jaw types and shortens set-up times, therefore reducing costs.

Robust clamping faces guarantee reliability and save time
The sharp, long and extremely stable clamping faces on three planes dig into the workpiece during the clamping process for absolutely secure holding due to the resulting form-fit clamping. Compared with conventional embossing systems, the case-hardened universal top jaws are substantially more robust. They also eliminate one entire operation including the required peripheral equipment, because additional embossing of the workpieces in an embossing station is superfluous with the SZKU.
Highly controlled production with automated loading
Due to the cutting edge geometries, the workpieces are automatically centered during the clamping process, which eliminates the possibility of becoming jammed. This makes the universal top jaw from SCHUNK ideal for automated machine loading, as well.
The SZKU with a metric tongue and groove can be used for machining of rough parts on all standard quick-change chucks. The tongue and groove design ensures especially high repeat accuracy. The top jaw is available in the standard sizes 160, 200, 250 and 315.
