Minimize set-up times and costs while achieving maximum precision with Schunk toolholders

Story added 18 February 2010.

MORE NEWS

The customised hydraulic expansion toolholders from Schunk are an effective way to minimize set-up times and costs while achieving maximum precision. For this purpose, the extremely large hydraulic expansion toolholders and arbors are often adjusted to the users&rsquo special requirements. This ensures that high precision and process reliability can be maintained in the long run. The latest example from Schunk is an arbor for components with a bore-diameter of 500mm.

Stators for large electric motors, gearbox parts for wind power plants, large components for power plants and the petroleum industry can all be clamped quickly and precisely with the micron-precision specialist solutions from Schunk. When working with specialist orders, the toolholding and workholding experts follow the process from the first enquiry through to engineering design, assembly and then follow through with subsequent maintenance to provide a complete solution for the end user.

Highly Precise Clamping - Even For Heavyweights

Even the largest of components can be clamped safely and precisely with the new XXXL-size hydraulic expansion arbor from Schunk. The diameter of this arbor amounts to more than 500mm. Instead of clamping claws or large lathe chucks, the arbor assures that the large and heavy workpieces, weighing more than a ton are precisely held within seconds. The XXXL hydraulic expansion arbor clamps workpieces deformation-free and gently with an excellent repeat accuracy of <0.01mm. This value cannot be achieved on the workpiece dimension with other clamping devices. Locating pins additionally guarantee exact alignment. Mounted on a rotary table, the heavy duty arbor from Schunk allows machining with one single set-up.

The large size of the hydraulic expansion chucks and arbors from Schunk are capable of achieving maximum precision with a very short set-up time. Process reliability is increased and the costs are also reduced. The fields of application for special solutions are extremely diverse ranging from quick-change chucks for machining large gears and applications on lathes or grinding machines up to sophisticated inspection devices. The solutions are designed specifically for the individual workpieces, machines and individual process. Schunk has the capability to deliver solutions for all clamping requirements whether O.D or I.D clamping, manual or automatic actuation &ndash almost anything is possible.
