The new SINO-R from Schunk Inc. is a maintenance free toolholder especially well suited for rough milling.

The universal toolholder is based on an expansion technology system with a solid body as a pressure medium quickly clamping the cutting tool by using a simple actuation wrench. This simple operation saves unproductive machine down-time.

The excellent interaction of high radial rigidity and great dampening characteristics are special features that increase the smooth running of the tool. The result is a high tool life and increased material removal rates.

An additional plus for the user: the toolholder is flexible thanks to the use of intermediate sleeves. Nearly all common tool shank diameters can be clamped.

SINO-R holds your tool securely, with a maximum torque transmission (850 Nm (627 Ft-lb)), at a clamping diameter of 32mm (1.25"). It is precision-balanced standard to G 6.3 at 15000 rpm.

  • 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.

  • shank


    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

  • toolholder


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