ToolingToolingCartridges Precision (μm) Polygonal Taper Shank SumiPolygon ■ General Features SumiPolygon shanks feature keyless couplings with the characteristic polygonal shape, which bear cutting torque evenly on three surfaces, providing high rigidity and high index accuracy. G For support with non-standard design specifications, contact us directly. ■ Features ■ Coupling Structure ● Sizes Tapered + · Shank size PSC32 (DCSFMS = 32mm) to PSC80 (DCSFMS = Supported by 2 Faces 80mm) supported ● High Rigidity/High Precision · 1/20 polygon tapered shape supported on 2 faces for high rigidity · Keyless coupling distributes cutting torque uniformly to 3 faces, reducing fluctuations in cutting edge height · Repeatability when tools are changed is within ±2μm on all 3 axes ● Reduced Tool Change Time · Changing inserts on the machine is not needed so the tool change time is significantly reduced Improved Centring ● Coolant supported (up to 1MPa) ■ Repeat Accuracy Repeatability when tools are changed is within ±2μm on all 3 axes X-Axis (Radial Direction) Y-Axis (Centre Height Direction), Z-Axis (Lengthwise Direction) 3 X-Axis (Radial) Z-Axis (Centre Height) X-Axis±2μm Y-Axis ±2μm 2 Y-Axis (Length) 1 Z-Axis ±2μm 0 1 2 3 4 5 Tool Change Count (Times) G8
