The customized hydraulic expansion toolholders from SCHUNK are an effective way to minimize set-up times and additional costs while still achieving maximum precision. For this purpose, the extremely large hydraulic expansion toolholders and arbors are often adjusted to the users’ special requirements. This ensures that high precision and process reliability can be maintained in the long run. The latest example is an arbor for components with a bore-diameter of 500 mm.
Stators for large electric motors, gearbox parts for wind power plants, large components for power plants, or the petroleum industry - all of these are clamped quickly and precisely with the micron-precision special solutions from SCHUNK. The experts in toolholding and workholding accompany special orders from the first enquiry to engineering design, through assembly and follow through with subsequent maintenance.

High precise clamping even of heavyweights
That even large components can be clamped safely and precisely, proves the present hydraulic expansion arbor in XXXL-size from SCHUNK. The diameter of this arbor amounts to more than 500 millimeters. 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. It clamps deformation-free and gently with an excellent repeat accuracy of < 0.01 mm - a value which cannot be achieved at this workpiece dimension with other clamping devices. Locating pins additionally assure exact alignment. Mounted on a rotary table, the heavy duty arbor from SCHUNK allows machining with one single set-up.
Manifold field of applications: Milling, turning, controlling, grinding
The fields of application for special solutions are very manifold and the spectrum comprises quick-change chucks for machining large gears, applications on lathes, or grinding machines up to sophisticated inspection devices. They are designed specifically for the individual workpieces, machines, and requirements. This makes the willingness possible to find solutions for all the requirements: O.D.- or I.D. clamping, manual or automatic actuation - almost anything is possible.
