Overview
The Chiron FZ 12 FX S is a single-spindle 5-axis machining center from the Chiron FZ 12 platform family, configured with the FX swivel head and a direct-drive rotary table for simultaneous 5-axis interpolation. Designed for high-speed production of complex small-to-medium aluminum, titanium, and steel components, it combines Chiron's signature speed-oriented architecture with the geometric versatility required for aerospace, automotive, and medical applications.
The FZ 12 FX S uses a fork-type swivel head (A-axis) combined with a rotating table (C-axis) to achieve full 5-axis simultaneous interpolation with excellent accessibility to all workpiece faces. The direct-drive torque motor on the rotary axes eliminates mechanical backlash and enables continuous contouring at high feed rates — a critical characteristic for turbine blades, impellers, and complex structural components. The spindle runs up to 20,000 RPM with the standard configuration, with options for higher speeds in aluminum-focused applications.
Chiron integrates its SmartLine digital monitoring suite into the FZ 12 FX S, providing real-time process data, condition monitoring, and integration with MES/ERP systems. This makes the machine a natural fit for Industry 4.0 production environments where traceability and predictive maintenance are operational requirements alongside raw cycle time performance.
The FZ 12 FX S is a well-established choice for aerospace subcontractors producing structural brackets, fittings, and engine components, as well as automotive shops manufacturing complex aluminum castings and titanium suspension components. Its compact footprint relative to its capability makes it suitable for cell-based production layouts with robotic part handling.

Frequently Asked Questions
01
The FZ 12 FX S adds the FX swivel head configuration for simultaneous 5-axis interpolation, while the FZ 12 S is a 3-axis (or 3+2 indexed) vertical machining center. The FX S is designed for complex compound geometry that requires continuous 5-axis motion rather than indexed positioning.
02
Yes. Chiron offers the DZ 12 FX S, which is the dual-spindle variant of this platform. The DZ configuration doubles throughput for high-volume production where workpiece size fits within each spindle's work envelope.
03
Chiron offers its own automation solutions including the Variocell Uno and Variocell Pallet robotic loading systems designed to integrate directly with the FZ 12 FX S. Third-party robot integration is also supported through standard interfaces.
