Kurt’s HD and HDL vises and towers are designed for faster setups, larger workholding capacity, and greater flexibility and precision to handle a variety of part configurations. They replace the company’s DL430 DoubleLock and CT430 ClusterTowers.
The vises and towers, which are available in manual and hydraulic models, feature quick-change jaws and fewer components to reduce change-over time. With a half-turn of a hex key, the stationary jaw lifts off the vise or tower body, then resets and self-aligns quickly, without special tools.
The towers provide 0.0002" repeatable clamping accuracy from part to part and feature a self-adjusting holding block for clamping the same- or dissimilar-sized parts. An adjustable pre-load feature reduces handle turns for opening and closing clamping stations on the manual models. The towers are available with four, eight or 12 stations and a variety of jaw options.
The rigid, two-station HDL vises deliver as much as 6,316 lbs of clamping force at 70 lbs of torque. They feature an 80,000-psi ductile iron body with precision-machined steel components and a 4" opening in each station using a standard hard-jaw system. The manual model converts to hydraulic operation using a simple conversion kit.
The HD690 pull-type vise features a 9" jaw opening to clamp larger parts with minimal stationary jaw deflection, the company says. Designed with a rigid stationary jaw, the vise features top-down bolting to reduce deflection, and a tall body to reduce stress. High-precision roller bearings and a hardened vise screw mechanism are designed to enhance precision clamping and smooth operation.
