The first is the patented CentroteX System, which allows changeover of any workholding device on a machine within five minutes while maintaining accuracies, eliminating the need for an operator to indicate the workholding system during changeovers and dramatically decreasing machine downtime. This system has a common flange plate that is fitted to the machine spindle along with a bayonet mount on the drawtube. The sub plate with chuck or fixture is then coupled to this interface, rotated 15 degrees and locked via quick connect fasteners. The user-friendly CentroteX System can be mounted on any CNC machine and with most any workholding or fixture device allowing manufacturers to schedule their production scenarios according to their customer needs and not according to the workholding set-up on the machines. The second quick change system is Hainbuch's Spanntop Modular Chuck System. This one-of-a-kind system utilizes Hainbuch's original 10-second collet change for OD clamping. What if you want to changeover from OD clamping to precise ID clamping, without changing the clamping device? Not a problem with the Mando Adapt mandrel. Place the mandrel in the mounted clamping device and tighten three screws to lock the mandrel in the clamping device for extreme rigidity and precision. For rotating products, concentricity of 0.005 mm between taper and mandrel taper can be achieved. For stationary clamping devices repeatability of 0.003 mm is possible. This can be accomplished without adjusting. New to the Hainbuch modular system is the Jaw Module which is small and flexible; can be quickly changed; and covers a large clamping range. The result is a quick-change clamping solution for all situations. The new Jaw Module completes the circle of modularity and gives a new clamping dimension that opens up even more possibilities for users. All this with less weight and a smaller interference contour. In short: ID clamping, OD clamping and 3-jaw clamping all-in-one. Hainbuch America will be at Booth W-2413 in the Tooling & Workholding Systems Pavilion.
