Overview
The Mazak SYNCREX 25/9X is the flagship of the 25 mm SYNCREX range, combining 25 mm (0.984 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, bridging the gap between Swiss-type precision turning and multi-tasking machining for complex mid-size parts. This is the sweet spot machine for shops needing both Swiss-type precision and 5-axis contoured features in the most popular bar capacity range.
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.
What distinguishes the 25/9X 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. The 25 mm bar capacity combined with 5-axis opens up complex medical implants, aerospace fittings, and hydraulic manifold work. Typical configurations include 24-28 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 3,600 kg (7,937 lb) with a footprint of roughly 3.0 x 1.5 meters. Competitors include the Citizen M32-VIII, Star SB-20R Type G, Tornos SwissDECO 26, and Tsugami SS267 5AX. New machines price between $280,000 and $420,000.

Strengths & Limitations
Strengths
- 9-axis configuration with true 5-axis contouring through B-axis milling enables complex contoured surfaces and undercuts in the most popular 25 mm Swiss bar range
- 25 mm bar capacity is the sweet spot for medical, automotive, and hydraulic parts making this the most versatile 5-axis Swiss in the SYNCREX lineup
- 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
- Eliminates secondary milling operations by completing complex parts in a single Swiss-type cycle with 5-axis contouring capability
- Removable guide bushing provides flexibility for Swiss mode or chucker mode depending on part geometry requirements
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 10,000-15,000 RPM in this bar range, reducing surface speed on smaller diameters
- Starting price near $280K is significantly above the 25/7 and 25/8 models with the 5-axis capability adding substantial cost over conventional Swiss configurations
- As a newer platform, the SYNCREX 25/9X has limited application knowledge and setup best practices compared to established 5-axis Swiss machines

Frequently Asked Questions
01
Base SYNCREX 25/9X configurations start around $280,000. Fully equipped machines with bar feeder, parts catcher, high-pressure coolant, full live tooling complement, and B-axis milling setup run $360,000-$420,000. The 5-axis capability commands a premium over the standard 25/8 and 25/9 models.
02
Both share 9-axis 5-axis contouring capability with B-axis milling. The 38/9X has larger 38 mm bar capacity, more powerful spindles (7.5 kW main), and more tool positions but costs more and takes more floor space. The 25/9X is better suited for the majority of Swiss parts in the 12-25 mm range where the 38 mm capacity is unnecessary. Choose the 38/9X when parts exceed 25 mm diameter or require more spindle power for aggressive cutting in superalloys.
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
For bar-fed parts up to 25 mm diameter, the 25/9X can genuinely replace a small multi-tasking machine while adding Swiss-type rigidity and precision. The 5-axis milling and 9 axes of control bridge the gap between Swiss-type and multi-tasking. However, for parts requiring heavy milling, large work envelopes, or chucked operations on larger diameters, a dedicated multi-tasking machine remains the better choice.
