A company is replacing a currently available model of machining vise with an upgraded version of an older model. The D688 features an 8.8-in. jaw opening and repeatability to within 0.001 in. It is replacing the D675. The new model produces up to 7968 lb of clamping force with 80 ft˚lbf input torque. The D688 has a jaw capacity that is 25% greater than that of the D675 model, and its clamping torque is greater by 36%. The distance from the keyway to the stationary jaw is identical in the two models, so they can be easily aligned on a vise table. The vise is designed with an alloy steel screw mechanism and high-precision roller bearings. The vise has a porosity-free ductile iron body, which is designed to provide overall vise rigidity while absorbing machining vibration.
