Information
Clamping with wedge clamps GN 920 is achieved via the socket head cap screw and the wedge block which forces the clamping jaws outwards to hold the workpiece firmly against the end stops.
Wedge clamps offer the following advantages:
Compact construction
High clamping forces
Simple to manipulate
Long retention of clamping force
Wedge block and clamping jaws are linked together by a flat guide. This method of construction also enables the use of wider clamping jaws thereby avoiding the supply of additional loose components with this type of wedge clamp.
Wedge clamps are preferably used for multiple clamping point applications, but they can also be used for single point clamping applications. Furthermore they lend themselves to hydraulic or pneumatic operation.
