Overview
The Mazak SYNCREX 20/9 is the advanced-configuration model in the 20 mm SYNCREX range, offering 9 axes of CNC control for complex Swiss-type production. With 20 mm (0.787 in) maximum bar capacity and an additional axis over the 20/8, this machine enables more sophisticated simultaneous machining operations and expanded milling capability for intricate small parts in medical, dental, electronics, and automotive applications.
The main spindle delivers 5.5 kW (7.5 hp) at 8,000 RPM through a collet system accepting bar stock up to 20 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 model, 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 22-26 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 3,000 kg (6,614 lb) with a footprint of roughly 2.7 x 1.4 meters. Competitors include the Citizen L20-XII, Star SR-20J II Type C, and Tornos SwissDECO 26. New machines price between $230,000 and $350,000.

Strengths & Limitations
Strengths
- 9 axes of simultaneous control enable complex multi-plane machining operations that the 7 and 8-axis 20 mm models cannot perform efficiently
- 20 mm bar capacity covers a wide range of precision turned parts including dental abutments, hydraulic fittings, and electronic housings
- MAZATROL SmoothG conversational programming reduces setup time compared to traditional Swiss G-code programming on Citizen and Star platforms
- 22-26 tool positions provide ample tooling for complex multi-feature parts with both main and sub-spindle operations
- Removable guide bushing provides flexibility for Swiss mode or chucker mode depending on part geometry and material utilization requirements
- Additional axis over the 20/8 enables compound-angle features and multi-plane milling directly in the Swiss-type cycle
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 10,000-12,000 RPM in this bar range
- Higher price point than the 20/7 and 20/8 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 and Star platforms

Frequently Asked Questions
01
Base SYNCREX 20/9 configurations start around $230,000. Production-ready setups with bar feeder, parts catcher, high-pressure coolant, and full live tooling complement run $290,000-$350,000. The additional axis commands a premium over the 20/7 and 20/8 models.
02
The 20/9 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 that the 8-axis model handles less efficiently. The 20/9 also supports more tool positions (22-26 vs 20-24). For standard Swiss turning with cross-working, the 20/8 is sufficient; for parts requiring complex milling operations, the 20/9 provides the additional capability.
03
If your parts require standard Swiss turning with drilling, cross-drilling, and basic milling, the 20/8 is sufficient and costs less. Step up to the 20/9 when parts require compound-angle features, multi-plane milling, or you need the additional tool positions for complex multi-feature parts that would otherwise require multiple setups.
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.
