pull-down elements are suitable for clamping and pulling down clamping surfaces that are unmachined or pre-machined onto the guideway or onto the supplied clamping bolts;
this way workpieces can be clamped almost exactly parallel to the guideway for machining;
the direct contact to the clamping bolts largely reduces vibrations in the workpiece.
type 1: pull-down set low; type 2: pull-down set high;
