High rigidity plus minimal run-out means better surface finish
-
In modern machining environments where high-speed milling, multi-task turn-mill centres and ultra-tight tolerances are the norm, the tool-holder interface becomes a strategic component—not just a fixture. XiRay’s CNC PSC Tool Holder series answers that shift by combining the PSC (Polygon Shank Conical) interface standard with advanced clamping methods—particularly shrink-fit—and flexible configurations for both milling and turning operations. According to XiRay’s website, the PSC Tool Holder Series “are advanced tool holding solutions designed to combine the high rigidity of the Polygon Shank Coupling (PSC) system with the precision and clamping strength of shrink fit technology.”
Product Overview
The CNC PSC Tool Holder supports the PSC interface (ISO 26623) and is available in multiple forms: one-piece shank holders, dedicated holders for turning/milling centres, and modular turning holder versions. XiRay lists the sub-categories: “PSC one-piece shank”, “PSC holder for turning-mills series” and “Modular PSC turning holder”. With this unified interface strategy, manufacturers can standardise on one tool-holder family that spans high-speed finishing, drilling/reaming, static milling and driven/live-tool turning operations.Key Features & Benefits
PSC Interface Compliance: Because the polygon-shank conical coupling provides large contact surfaces and high torsional rigidity, the mounting is far more repeatable and suitable for driven and multi-task machines.Shrink-Fit Clamping & Precision: XiRay highlights uniform 360° clamping force, very low run-out and strong stability under high-speed conditions. According to their data, run-out accuracy is ≤ 3 µm at 3× D and speed capability up to ~40,000 rpm (depending on size).
Flexible Multi-Mode Application: The “PSC holder for turning-mills” series supports configurations like double-side turning, 45° turning, radial/axial holders—letting front-line operations deploy one interface platform across multiple machine tool types.
Industry-Targeted Design: The series is geared toward automotive, electronics, medical device and precision part manufacturing—areas where cycle-time, surface finish and tool life are under high pressure.
Why Choose This CNC PSC Tool Holder?
For manufacturing operations looking to upgrade to agile, high-mix, multi-axis setups—or those seeking to rationalise tooling across turning and milling—this tool-holder series offers multiple strategic advantages:Tool-holder standardisation: One interface across static and driven tooling, turning and milling, reduces inventory types and simplifies logistics.
Improved machining outcomes: High rigidity plus minimal run-out means better surface finish, tighter tolerances and longer tool/spindle life.
Faster change-overs and higher uptime: The repeatable and robust PSC interface supports quicker, more reliable setup and tool changes—critical in flexible production.
Application & Best Practice
To extract full value: ensure your machine spindle and holder pocket comply with PSC/ISO 26623 tolerances; for shrink-fit versions follow the induction-heating or clamping protocols suggested by XiRay; in turn-mill centres choose the modular PSC turning-mill versions to standardise interface across both static and driven tooling.
