2 SCHUNK hydraulic expansion Toolholders More than 75,000 implemented, customer-specific s and tool clamping in the micron range. For more than 35 years SCHUNK has been developing and manufacturing hydraulic expansion toolholders and hydraulic expansion arbors for high-precision lathing, milling, boring, serrating, grinding, checking, mounting and balancing. With us, you'll profit from the know-how of the world's largest supplier and the market leader for hydraulic expansion technology. Tailor-made perfection. From the initial discussion through to integration of the finished clamping element in your processes, you benefit from our customer-orientation and development expertise. By providing an individualized engineering design, we guarantee optimum adaptation of the clamping device to the workpiece and machine. As more than 75,000 successful customerspecific solutions for extreme requirements show: SCHUNK offers perfect, tailor-made hydraulic expansion toolholders. You benefit from the No. : Customer-specific clamping solutions Can be installed anywhere Optimal surface clamping for very high torques Multiple workpieces can also be clamped Very easy handling Maximum run-out and repeat accuracy < mm - Increases the tool's service life Excellent vibration damping - Better surface quality - Prevents micro-blowouts on the tool's cutting edge

3 SCHUNK hydraulic expansion Technology Customer-specific s Our Experience. Your Benefit. Turning and milling of a stator housing Engine production, mechanical engineering, automotive Machining at a high centering and run-out accuracy, whereby the unmachined contact surface of the workpiece also complicates this operation. The hydraulic expansion arbor is designed to hydraulically cushion the workpiece support. Therefore the uneven, unmachined workpiece surface has no influence on the accuracies. DMB turn/mill center is done directly via a hand pump. High-precision use of printing sleeves Printing industry Centering and clamping of the printing sleeves has to be done at a high run-out accuracy. The printing sleeves are clamped on an expansion arbor, which allows fast retrofitting and exchange of the rollers on flexographic printing presses. This solution considerably lowers set-up times and costs. Due to the high run-out accuracy of the expansion arbor, an excellent print image is ensured. Printing machines with cylindrical and centric mounting Manual clamping. Hobbing of cylindrical gear teeth Tool and mold making industry, machine building industry The cylindrical gear has to be exactly clamped and simultaneously centered. The hydraulic expansion arbor centers the cylindrical gear. Axial clamping is carried out via a counter support. The system is automatically loaded at a high cycle rate. Gleason P60 and P90 This solution is based on axial force clamping.

4 SCHUNK Hydraulic Expansion Toolholders Customer-specific s Grinding Brake Disks Automotive Axial clamping is necessary in addition to workpiece clamping. The workpiece is clamped on a permanently clamped hydraulic expansion arbor. The system can be unclamped via the machine's pressure cylinder. The hydraulic expansion arbor centers the brake disk during the machining process. The axial clamping is ensured by an additional screw and nut. Cylindrical grinding machine from Haas The system is permanently clamped by a spring. Gear grinding of a gear (bevel gear) Machine building, vehicle construction, tool and mold making industry The workpiece requires additional centering during the clamping procedure. 3 The workpiece is automatically loaded onto the hydraulic expansion arbor at a high cycle rate. The workpiece is clamped by the hydraulic expansion arbor and is simultaneously centered. Axial clamping is done via an on-line counter-support and a pendulum disk. Controlling the air system ensures secure workpiece positioning and clamping. Reishauer RZ400 or Kapp KX300 3 Counter-support with pendulum disk is done via power clamping. Vertical gear slotting of an internal gear Machine building, vehicle construction, tool and mold making industry The internal gear needs to be centered during the clamping operation and axially clamped by a rotary finger. The entire clamping operation should be as low-deformation as possible. The internal gear is clamped and centered with little deformation in a hydraulic expansion toolholder. Axial clamping is via an additional draw bar. Gleason / Liebherr Customer-specific hydraulic expansion toolholder Radial clamping is performed manually, axial clamping is via the machine cylinder.
