Compact powerhouse with a fixed jaw

The trend toward automated machine loading also affects the clamping devices: there is an increasing demand for compact clamping modules with optimized interfering contours that can be loaded and unloaded by robots or gantries. SCHUNK, the competence leader for clamping technology and gripping systems is therefore further expanding its family of high-performance SCHUNK TANDEM plus clamping force blocks. The smallest TANDEM plus (size 64) is available starting immediately with a fixed jaw, for fixed definition of the zero point.


This eliminates the possibility of the reference point moving. The compact clamping force block is ideal for fully automated serial production of small parts. In addition, it can be combined in series with clamping force blocks of the same type for clamping of long parts, such as profiles. Two versions are available for pneumatic (KSP-F plus) or hydraulic (KSH-F plus) actuation. The clamping force amounts to 4,000 N and the jaw stroke is 2 mm.
Numerous variants


SCHUNK TANDEM plus clamping force blocks develop enormous forces in minimal space. Their one-piece rigid base body, the wedge-hook kinematics and long, ground jaw guides provide for concentrated clamping forces of up to 55 kN. At the same time they ensure excellent repeat accuracy of up to 0.01 mm. This makes the clamping force blocks ideal for the most demanding milling tasks with a high rate of metal removal, high number of cycles, and minimal tolerances.


The optimized outer contour and minimal clearance prevent the accumulation of dirt or chips, and dust in the clamping module. Special fitting screws ensure that the clamping modules can be changed at high repeat accuracy. The standardized powerhouses are available in a unique diversity of variants: actuated pneumatically, hydraulically, by spring force or manually, in sizes between 64 and 250 mm, with a standard stroke, long stroke or as a console clamping module with a fixed jaw.


They are suitable both for top jaws with a tongue and groove design as well as for jaws with fine serration. For an optimal overview of the many options, the SCHUNK website offers a free quickfinder, which facilitates the search for the optimal clamping force block. Five clicks are all it takes for the tool to find the suitable models.
