The Whittemore Co. represents manufacturers of several products and services in the workholding systems and accessories arena. From simple machine vises to complete custom fixtures; standard chucks, mandrels, centers and face drivers, to completely engineered chucking solutions for rotating and non-rotating workpieces, we have the answer.
Whether your project calls for a simple standard chuck or vise, or a fully-engineered fixture or workholding system for production machining, we have the solution. We have the right product for nearly every workholding application.
Kurt’s mission is to provide the highest quality workholding products and solutions while developing the most innovative new products and services to meet our customer’s changing needs.
Since 1960, Kurt has been providing solutions to CNC machine workholding problems with a deep understanding of how workholding integrates into today’s quality driven manufacturing process. Our experience is unparalleled.
At Kurt, we provide the complete spectrum of workholding solutions, from a full line of single and double station vises, our DX6 and HDL vises, 5-axis vises, complete modular vise systems, a wide variety of vise accessories and jaws, to custom engineered workholding packages and sub-systems. We’ve built our reputation as workholding specialists by assisting automotive, aerospace and other metalworking-intensive industries to improve quality and reduce cycle times.
The HDL Anglock® Vises are high density long vises with two clamping stations which are either manually or hydraulically actuated. They provide repeatable clamping to 0.0002″. They combine high density with heavy duty features. Designed on a rugged 80,000 PSI induction hardened ductile iron body with steel components, both models provide strength, rigidity and long term accuracy while absorbing machining vibration.
