In today’s machining environment, where rapid change-overs, multi-tasking centres and high precision finishing are the norm, the tool-holder interface has transformed from a passive element to a strategic enabler. The CNC PSC Tool Holder (Hydraulic/Internal Cooling) embraces this evolution by leveraging the PSC (Polygon Shank Conical) standard under International Organization for Standardization (ISO 26623) and pairing it with advanced clamping and cooling features to meet demanding production realities. According to XiRay’s website, the PSC series emphasises compatibility, rigidity and versatility across static and driven tool applications. https://www.xiray-tools.com/psc-tool-holder-series/ Product Overview This CNC PSC tool holder utilises the PSC shank interface which is increasingly adopted for multi‐machining centres. The hydraulic clamping variant with internal coolant feed ensures the holder remains rigid and thermally stable even under heavy duty conditions. Its modular design allows adaptation across skid-style lathes, turn-mill centres and high-speed milling machines. Key Features & Benefits PSC Interface Advantage: The polygonal shank coupling under the ISO 26623 standard offers dual-contact (taper + face) and large contact area, delivering high torsional rigidity, excellent repeatability and fast tool changes. Hydraulic Clamping & Internal Cooling: With hydraulic clamping, uniform radial pressure delivers minimal run-out and high stiffness; the internal coolant feed ensures stable thermal conditions and coolant delivery right to the cutting edge—crucial for finishing and high feed operations. Versatility & Modularity: This tool holder fits both driven and static operations — a key trend as manufacturers rationalise interfaces across turning and milling machines. Modular adaptors allow quick change-over, reducing downtime. Improved Productivity & Tool Life: By utilising the PSC interface’s rigidity and precision fit, vibration is reduced, surface finish improves and tool life is extended. These benefits align with broader market demand for high-precision manufacturing in automotive, aerospace and medical segments. Why Choose This CNC PSC Tool Holder? For workshops upgrading to flexible machining centres or striving to simplify tooling inventories, this holder delivers significant advantages: Interface consolidation: One interface covers static and driven, turning and milling — helping reduce inventory and complexity. Enhanced machining outcomes: Better rigidity, minimal run-out and strong coolant control lead to tighter tolerance parts and improved finishes. Reduced downtime: Quick-change ready and repeatable mounting minimize change-over time — important in high-mix production. Application & Best Practice To reap full benefit: ensure your spindle and turret interfaces are rated for ISO 26623/PSC; follow correct hydraulic clamping and coolant feed setup; in a multi-task cell select the PSC modular adaptors to switch between driven milling and static turning quickly. Over-spanning the holder’s designed rpm or feed can reduce benefits.
