Hydraulic Expansion Arbor has VERO-S Quick-Change Capabilities

With more than 75,000 implemented, customer-specific solutions, SCHUNK has been developing and manufacturing  hydraulic expansion arbors for high-precision applications in milling, hobbing, turning, grinding, assembly, inspection and balancing for over 35 years. The hydraulic expansion technology is now with VERO-S Module quick-change capabilites.

There are many benefits to using SCHUNK hydraulic expansion arbor with VERO-S Module quick-change system for customer-specific clamping solutions, including:

Top tool change in seconds, which allows quick and easy flexing of machine, rigid assembly with up to 25,000 Newtons of pull down force created by the VERO-S Module, ease of operation (VERO-S Module is spring clamp-air to unclamp), maximum runout and repeat accuracy of <= 0.005 mm, (when used with 0.000 mm axial runout spindle) and excellent vibration damping.

Related Glossary Terms

  • arbor


    Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • turning


    Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
