Knoxville, Tennessee – Hoffmann Group USA’s GARANT Xtric centering vise is equipped with a chuck jaw quick-change system which enables easy, tool-free changeover. A click mechanism gives the vise an interchange accuracy in the micrometer range.

Top jaws, which can be rotated 180° without using tools, allow for a large clamping range and high variability when fixing components. For this purpose, the top jaws are inserted into a dovetail and pushed down via two spring plates until they engage. There is no need to remove and re-thread the spindle nut. This click-and -clamp system can significantly reduce setup costs.

With its rotating top jaws, the GARANT Xtric provides a clamping range of 0 to 144mm in the model 80S, and 0 to 194mm in the model 80M. All models are alternatively available with pivot jaws.

If a clamping force of 25kN is applied directly on the component, the vise will also be suitable for clamping unfinished parts. If a gripper jaw with GARANT tooth form is used, pre-stamping can be eliminated. For customers that already use the Lang system, there are suitable top jaws with the Lang system tooth form. The top jaws are available both uncoated and coated.

To clamp larger workpieces using multiple centering vises, the center can be adjusted to the micrometer, and if required, can be shifted by up to 0.5mm on each side (by 1mm in total).

Longitudinal grooves for precise alignment on the machine table, bores for the Lang positioning system, and adapter plates for clamping on the GARANT Zero Clamp zero-point system round out the range. Adaptation to other zero-point clamping systems is also possible.
