External Tool Holders Polygon - Shank Holder PSC Features The Sumitomo polygon shank holders enable an extremely high stiffness connection between machine and tool. The conical polygon can take high bending and torque moments based on the combination of the face contact to the spindle. This self-guiding coupling system offers high precision and a repeatability of ± 2µm in X, Y and Z axis. While using this easy and quick coupling system it is pos- sible to gain higher machine utilization time as the set-up and tool change times are reduced. The compact design and the high stiffness connection to the spindle offer a versatile use e.g. on multi-task machi- nes, machining centers and turning-milling centers.
