SVP-Mini, SVP-RM Manually Actuated Clamping Devices

July 01, 2014

The SVP-Mini and SVP-RM from SCHUNK are manually actuated clamping devices that run on factory-defined set pressure, reportedly saving time and energy, reducing setup costs, and eliminating operating errors. They can be fastened vertically or horizontally at a workstation, or used directly on the TRIBOS polygonal toolholders at the machine spindle.

SVP-Mini and SVP-RM are the ideal supplement for operators who use TRIBOS for micro and high-speed cutting. They are more economical than the TRIBOS clamping devices, and will always generate the clamping pressure necessary for tool change. Due to the firmly integrated expansion sleeve, no reduction inserts are necessary and tool change is simplified.

With a runout and repeat accuracy of less than 0.003mm at an overhang of 2.5 x D and a balancing grade of G 2.5 at 25.000 rpm, the TRIBOS polygonal clamping technology will fulfill any requirement. Instead of a round mounting hole, the precision toolholders have polygon-shaped holes for the tool. A defined pressure is actuated from the outside, the mounting hole deforms to a cylindrical shape and the tool can be easily inserted into the toolholder. Then the pressure is reduced, the internal diameter moves back to its initial polygonal shape because of the elasticity of the material, and due to the internal stress of the steel, the tool is clamped by force-fit.
