SCHUNK is introducing their new hydraulic expansion extension TENDO-SVL. The extension transforms almost every precision toolholder into a highly versatile device for narrow spaces independent from the spindle interface. The precise run-out, excellent vibration dampening and the internal coolant supply ensure outstanding machining results and a long tool life.

Due to the radial clamping actuation, tools can even be changed in the machine. The maximum torque of the hydraulically clamped extension ensures that tools are held securely for all drilling, reaming and finish milling operations. All theses features make the extension the benchmark for quality, ergonomics, set-up time and cost.

TENDO-SVL extensions are available in both inch and metric versions.

Related Glossary Terms

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • gang cutting ( milling)

    gang cutting ( milling)

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

  • 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.

  • toolholder


    Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
