Key data at a glance

The Vario•Tec centering vise offers a convenient and variable support and positioning system for (semi-) finished workpieces. The Vario•Tec clamping jaws contain movable pins with high positioning accuracy, which are blown out row by row with compressed air and can be pushed back individually when not in use, thus generating specific clamping angles. This facilitates the easy and repeatable setting of the desired configuration and eliminates the need for additional workpiece end stops and parallels.
