The Multiflex vise series, a modular clamping system, is able to clamp several workpieces at the same time on the machine tool table. Interlocking ground comb teeth locate the vise jaws along the length of the base, and also position each moving vise jaw against the fixed jaw that supports it. Tightening the screw on the wedge-shaped moving jaw creates the "pull down action" that provides the clamping force, the company says. Up to nine workpieces can be clamped simultaneously on the same base. The hardness of the components is 60 HRC, allowing the system to resist wear.
