Overview
The Mazak SYNCREX 25/9 is the advanced-configuration model in the 25 mm SYNCREX range, offering 9 axes of CNC control for complex Swiss-type production of mid-size precision components. With 25 mm (0.984 in) maximum bar capacity and a ninth axis over the 25/8, this machine enables more sophisticated simultaneous machining operations and expanded milling capability for intricate parts in medical, automotive, aerospace, and hydraulic applications.
The main spindle delivers 5.5 kW (7.5 hp) at 8,000 RPM through a collet system accepting bar stock up to 25 mm diameter. The sub-spindle provides 3.7 kW (5 hp) at 8,000 RPM for back-working operations and part pickup. The guide bushing supports the bar at the cutting zone for Swiss-type rigidity, and is removable for non-guide-bushing mode on shorter parts.
The 9-axis configuration adds a dedicated milling axis over the 8-axis 25/8, enabling more complex simultaneous operations including multi-plane milling, advanced cross-working, and compound-angle features. Live tooling stations provide high-speed milling, cross-drilling, angular machining, and tapping. Typical configurations include 22-28 tool positions combining fixed turning tools, rotary live tools, and back-working stations.
The MAZATROL SmoothG CNC control supports both conversational programming for standard Swiss operations and full G-code for complex multi-axis features. The machine weighs approximately 3,400 kg (7,496 lb) with a footprint of roughly 2.9 x 1.4 meters. Competitors include the Citizen L25-VIII, Star SR-20R Type C, Tornos SwissDECO 26, and Tsugami SS267. New machines price between $250,000 and $370,000.

Strengths & Limitations
Strengths
- 9 axes of simultaneous control enable complex multi-plane machining operations that the 7 and 8-axis 25 mm models cannot perform efficiently
- 25 mm bar capacity hits the most popular Swiss-type size range, covering bone screws, dental implants, hydraulic fittings, and automotive components
- 22-28 tool positions provide ample tooling for complex multi-feature parts with both main and sub-spindle operations
- MAZATROL SmoothG conversational programming reduces setup time compared to traditional Swiss G-code programming on Citizen and Star platforms
- Additional axis over the 25/8 enables compound-angle features and multi-plane milling directly in the Swiss-type cycle
- Removable guide bushing provides flexibility for Swiss mode or chucker mode depending on part geometry and material utilization requirements
Limitations
- 9-axis programming complexity requires more skilled programmers or advanced CAM software compared to simpler 7 and 8-axis Swiss configurations
- 8,000 RPM main spindle speed is lower than some competitors offering 10,000-15,000 RPM in this bar range
- Higher price point than the 25/7 and 25/8 may not be justified for shops primarily running standard Swiss turning operations
- Newer entrant to Swiss-type market with limited SYNCREX-specific track record compared to established Citizen L25 and Star platforms

Frequently Asked Questions
01
Base SYNCREX 25/9 configurations start around $250,000. Production-ready setups with bar feeder, parts catcher, high-pressure coolant, and full live tooling complement run $310,000-$370,000. The additional axis commands a premium over the 25/7 and 25/8 models.
02
The 25/9 adds a ninth axis of control, providing a dedicated milling axis for more complex simultaneous operations. This enables multi-plane milling, compound-angle drilling, and advanced cross-working features. The 25/9 also supports more tool positions (22-28 vs 20-25). For standard Swiss turning with cross-working, the 25/8 is sufficient; for parts requiring complex milling, the 25/9 provides the additional capability.
03
The 25/9X adds a B-axis on the milling spindle for true 5-axis contouring capability. The standard 25/9 has 9 axes optimized for advanced Swiss turning with expanded cross-working but cannot produce complex contoured surfaces or undercuts. If your parts require 5-axis contoured features, the 25/9X is required; for complex turned parts with multi-plane milling, the 25/9 is sufficient and costs less.
04
For standard Swiss operations, MAZATROL conversational programming handles most turning, drilling, and simple milling. For advanced 9-axis operations, dedicated CAM software such as Esprit (by Hexagon), GibbsCAM, or SOLIDCAM supports the SYNCREX platform. Post processor development may be needed for the 9-axis configuration.
