Spring-loaded 3-jaw clamping force blocks
Spring-loaded 3-jaw clamping force blocks in compact design with high clamping forces. These are available with standard jaw stroke and long stroke.

Advantages – Your benefits

  • 3-jaw clamping force blocks for cylindrical workpieces
    This low-deformation clamping, especially for thin-walled workpieces
  • Spring-packaged clamping force blocks
    Media-independent workpiece clamping, especially for tombstone or storage applications
  • Patented monitoring of the base jaw position via dynamic pressure
    Know whether the vise is open or clamped
  • Workpiece presence control through the base jaw
    Enables automated loading of the clamping force block
  • Precision wedge hook clamping force block for top-quality demands
    Allows excellent machining results
  • Square design with ideal external contour
    Ideal for 6-sided machining in two set-ups with great lateral accessibility
  • High efficiency of the wedge hook system
    Process-reliable clamping due to high clamping forces
  • Base jaws with tongue and groove and fine serration as a dual interface as standard
    High flexibility of system jaws
  • Optimal jaw support due to the use of a very long base jaw guidance
    Allows high clamping forces at a long service life
  • All sides of the functional parts are hardened and ground
    Ensures a long service life

Options and special information

  • Spring-loaded powerhouses for tombstone and storage solutions now also as 3-jaw vises
    Whereas TANDEM KRF3 previously stood for high-performance 2-jaw clamping force blocks for tombstone and accumulator solutions, SCHUNK is now expanding the modular system of spring-loaded clamping force blocks with TANDEM KRF3 to include 3-jaw clamping force blocks. These clamping force blocks make it possible for cylindrical workpieces to now be clamped with less deformation without the need for special chuck jaws and with better force distribution.
  • The great advantage of these compact clamping devices is that the clamping force is fully maintained even after complete removal of the compressed air. Another important aspect is the compatibility of the most common designs, so that existing KSF3 vises can be replaced 1:1 by the KRF3 vises.
