Overview
The Mazak SYNCREX 25/7 is the entry-level configuration in the 25 mm SYNCREX range, offering 7 axes of CNC control for cost-effective Swiss-type production of mid-size precision components. With 25 mm (0.984 in) maximum bar capacity, this machine hits the most popular Swiss-type size range, covering the majority of medical, automotive, and electronic precision turned parts while keeping the axis count streamlined for simpler programming and faster setup.
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 including cutoff pickup, back-facing, and secondary drilling. 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 where material savings matter.
The 7-axis configuration provides the essential Swiss-type motions for main and sub-spindle turning with cross-working capability. This streamlined axis count reduces programming complexity compared to 8 and 9-axis models while still enabling simultaneous main and sub-spindle operations with live tooling. Typical configurations include 18-22 tool positions with fixed turning tools and live rotary tools.
The MAZATROL SmoothG CNC control provides Mazak's signature conversational programming, making the SYNCREX 25/7 accessible to shops without specialized Swiss programming expertise. The machine weighs approximately 3,000 kg (6,614 lb) with a footprint of roughly 2.7 x 1.3 meters. Competitors include the Citizen L25-VIII, Star SR-20J, and Tsugami S25. New machines price between $200,000 and $310,000.

Strengths & Limitations
Strengths
- 25 mm bar capacity hits the most popular Swiss-type size range, covering orthopedic bone screws, dental implants, hydraulic fittings, automotive sensor housings, and electronic connectors
- 7-axis configuration simplifies programming and setup compared to 8 and 9-axis models while maintaining simultaneous main and sub-spindle capability
- MAZATROL SmoothG conversational programming reduces setup time by 30-50% compared to traditional Swiss G-code programming on Citizen and Star platforms
- Removable guide bushing provides flexibility to run Swiss mode for long slender parts or chucker mode for shorter parts with better material utilization
- Lower entry price than the 25/8 and 25/9X makes this the most affordable entry point into 25 mm Swiss-type production on the SYNCREX platform
- 5.5 kW main spindle provides adequate power for cutting stainless steel and titanium at 25 mm bar diameters
Limitations
- 7-axis configuration lacks the additional cross-working and milling axes found on the 25/8, limiting simultaneous operation complexity and off-center feature capability
- 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 small-diameter aluminum and brass
- Fewer tool positions (18-22) than high-end Swiss machines from Citizen and Star that offer 30+ positions in the 25 mm class
- Newer entrant to Swiss-type market means limited SYNCREX-specific track record compared to Citizen L25 and Star SR-20J with decades of proven production history

Frequently Asked Questions
01
Base SYNCREX 25/7 configurations start around $200,000. Production-ready setups with bar feeder, parts catcher, high-pressure coolant, and live tooling complement run $260,000-$310,000. The 7-axis model is the most affordable entry point in the 25 mm SYNCREX range.
02
The 25/8 adds an eighth axis of control, providing additional cross-working capability for more complex simultaneous operations. The 25/8 accommodates 20-25 tool positions versus 18-22 on the 25/7, and enables off-center milling and hexagonal machining that the 7-axis model cannot efficiently produce. For standard Swiss turning with back-working, the 25/7 is sufficient; for complex multi-feature parts, step up to the 25/8.
03
The Citizen L25-VIII is the dominant machine in 25 mm Swiss with a massive installed base. It offers higher spindle speeds (10,000 RPM), more tool positions, and Citizen's proven Cincom programming. The SYNCREX 25/7 counters with MAZATROL conversational programming and a simpler 7-axis configuration that reduces the learning curve. For dedicated Swiss production, Citizen has the track record; for shops wanting easier programming, the SYNCREX is compelling.
04
Yes. The guide bushing is removable, allowing the machine to operate in non-guide-bushing (chucker) mode for shorter parts where the length-to-diameter ratio does not require guide bushing support. This reduces bar remnant waste and improves material utilization on parts with L/D ratios under 3:1.
