In the ever-evolving world of precision machining, manufacturers face growing pressure to deliver shorter cycle times, sharper tolerances and seamless tool changes. The CNC PSC Tool Holder from Jiaxing XiRay is designed exactly for such demands — it integrates the modern PSC (Polygon Shank Conical) interface standard with high-rigidity shrink-fit and modular tooling strategies, offering a platform built for next-generation machining. According to XiRay, the PSC series combines “the high rigidity of the Polygon Shank Coupling (PSC) system with the precision and clamping strength of shrink fit technology.” https://www.xiray-tools.com/psc-tool-holder-series/ Product Overview The CNC PSC Tool Holder is engineered around the PSC interface (ISO 26623 standard) and offers variants including one-piece shank holders, turning-milling adaptors, and modular driven/static formats. XiRay’s PSC series lists sub-categories like “PSC one-piece shank,” “PSC holder for turning-mills series,” and “Modular PSC turning holder.” This single interface strategy allows shops to unify tooling across both milling and turning operations, reducing complexity while maintaining high performance. Key Features & Advantages PSC Interface Compatibility: The polygon-shank conical coupling enables large contact surfaces, superior torsional rigidity and consistent repeatability — especially important in driven-tool and high-speed operations. Shrink-Fit Based Clamping & Precision: XiRay emphasises the use of shrink-fit technology to provide uniform 360° clamping force, minimal run-out (≤3 µm at 3×D) and balanced high-RPM performance. Modular Flexibility for Turn/Mill Applications: The “PSC holder for turning-mills” family includes configurations such as double-side, 45°, radial and axial turning holders — enabling the CNC PSC Tool Holder to adapt across a wide range of machine types. Targeted Industry Reach: XiRay positions the PSC series for sectors like automotive, electronics, medical devices and precision parts manufacturing — environments where tool change-over speed, surface finish and tool life are critical. Why Choose the CNC PSC Tool Holder? For manufacturing operations moving toward agile, multi-task or high-precision cells, the CNC PSC Tool Holder delivers strong strategic advantages: Unified tooling interface: One interface supports both static and driven tooling across turning and milling, simplifying inventory and tool-holder management. Improved machining quality: High rigidity coupled with precision clamping means fewer vibrations, better finishes and extended tool life. Faster change-overs & higher utilization: The repeatability and robust clamping of the PSC interface support rapid, reliable tool changes — essential in high-mix production. Application & Best Practice To maximise performance: Ensure your machine spindle and holder pocket conform to PSC specification tolerances; follow the induction heating or clamping protocols recommended by XiRay; in turn-mill or multi-task setups select the modular PSC-turning holders to standardise your tooling across static and driven applications.
