Kurt Manufacturing says its high-density, long vises with two clamping stations can increase machining center productivity. Manual and hydraulic models are available in 4" and 6" capacities to increase existing machining center output.
The 4" capacity HDLM4 model is suited for machining precise medical devices, small electronic parts and other small parts on small machining centers. The 6" capacity HDLM6 model is suited for machining large parts such as precision aerospace and automation components on large machining centers. Both vises provide repeatability to 0.0002".
Featuring an 80,000-psi ductile iron body with precision-machined steel components, the rigid vises can deliver as much as 6,316 lbs of clamping force at 70 lbs of torque. According to the company, the vises provide strength, rigidity and long-term accuracy while absorbing machining vibration. Both feature two clamping stations, each of which feature a full 3" or 4" opening and use the company’s hard-jaw system.
Additional features of the manual model include an adjustable pre-load design that minimizes pre-load range, thus reducing the turns of the handle required to open or close the vise. A holding block allows clamping same- or dissimilar-sized parts and allows pre-loading in the front or back jaw. Also, the work envelope accommpdates multiple parts, providing better spindle utilization, reduced tool change time and reduced machine travel from part to part, the company says.
The manual-model vises can be converted to hydraulic operation using a simple conversion kit, the company says.
