Overview
The Mazak SYNCREX 20/9X is the flagship of the 20 mm SYNCREX range, combining 20 mm (0.787 in) bar capacity with 9 axes of control and true 5-axis contouring capability. The X designation signifies the B-axis milling spindle that enables simultaneous 5-axis interpolation, setting this machine apart from conventional Swiss-type lathes and bridging the gap between Swiss precision turning and multi-tasking machining for complex small parts.
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.
What distinguishes the 20/9X is its 5-axis contouring capability through the B-axis milling spindle. This enables true simultaneous 5-axis interpolation for complex contoured surfaces, undercuts, and compound-angle features that conventional Swiss machines cannot produce. Live tooling stations provide high-speed milling, cross-drilling, and angular machining. Typical configurations include 22-26 tool positions.
The MAZATROL SmoothG CNC control supports both conversational programming for standard Swiss operations and full 5-axis G-code for complex contoured features. The machine weighs approximately 3,100 kg (6,834 lb) with a footprint of roughly 2.8 x 1.4 meters. Competitors include the Citizen L20-XII, Star SR-20J II Type G, and Tsugami SS207 5AX. New machines price between $260,000 and $380,000.

Strengths & Limitations
Strengths
- 9-axis configuration with true 5-axis contouring through B-axis milling enables complex contoured surfaces and undercuts that conventional Swiss machines cannot produce
- 20 mm bar capacity addresses the high-demand size class for medical implants, dental components, and electronic connectors
- B-axis on the milling spindle enables compound-angle drilling, contoured surface milling, and undercut features directly in the Swiss-type cycle
- MAZATROL SmoothG supports both conversational programming for standard operations and full 5-axis G-code for complex contoured work
- Removable guide bushing provides flexibility for Swiss mode or chucker mode depending on part geometry requirements
- Combines Swiss-type precision turning with multi-tasking 5-axis capability in a single compact machine, eliminating secondary operations
Limitations
- 5-axis contouring requires advanced CAM software (Esprit, GibbsCAM, or similar) and skilled programmers beyond standard Swiss expertise
- 8,000 RPM main spindle speed is lower than some competitors offering 10,000-12,000 RPM in this bar range
- Starting price near $260K positions this significantly above the 20/7 and 20/8 models with the 5-axis capability adding substantial cost
- As the most complex 20 mm SYNCREX model, application knowledge and setup best practices are still being developed across the user community

Frequently Asked Questions
01
Base SYNCREX 20/9X configurations start around $260,000. Fully equipped machines with bar feeder, parts catcher, high-pressure coolant, full live tooling complement, and B-axis milling setup run $320,000-$380,000. The 5-axis capability commands a premium over the standard 20/8 and 20/9 models.
02
The X designation means the 9-axis configuration includes a B-axis on the milling spindle for true 5-axis contouring capability. The standard 20/9 has 9 axes optimized for advanced Swiss-type turning with expanded cross-working. The 20/9X can produce complex contoured surfaces, compound-angle features, and undercuts that the 20/9 cannot. Both share the same bar capacity and spindle specs.
03
For standard Swiss operations, MAZATROL conversational programming handles most turning, drilling, and simple milling. For 5-axis contouring, dedicated CAM software is required. Esprit (by Hexagon), GibbsCAM, and SOLIDCAM all support the SYNCREX platform. Post processor development may be needed for the 9-axis configuration with B-axis.
04
If your parts primarily require standard Swiss turning with cross-drilling and basic milling, the 20/7 or 20/8 provides better value. The 20/9X is justified when parts require contoured surfaces, compound angles, or undercuts that would otherwise need secondary operations on a mill. The 5-axis capability adds both cost and programming complexity.
