With jaw openings of 8.8 in. and repeatabilities within 0.001 in., D688 vises generate up to 7,968-lb clamping forces with 80-ft-lb input torque. According to the manufacturer, this is up to 36% greater clamping force than comparable vises.
High-precision roller bearings and hardened vise-screw mechanisms distribute clamping forces precisely and evenly across jaw surfaces. And Anglock spherical segments in D688 movable jaws further reduce jaw lift. Porosity-free, 80,000-psi ductile iron vise bodies provide rigidity and absorb machining vibrations, while thick, baked epoxy finishes protect from corrosion and chipping.
