Overview
The Mazak SYNCREX 38/9 is the high-axis-count model in the largest SYNCREX bar capacity range, offering 38 mm (1.496 in) bar capacity with 9 axes of simultaneous CNC control including a B-axis milling spindle for true 5-axis contouring. This machine represents the most capable standard configuration in the 38 mm SYNCREX lineup, bridging the gap between the 8-axis 38/8 and the top-tier 38/9X with its extended feature set.
The main spindle delivers 7.5 kW (10 hp) at 7,000 RPM through a collet system accepting bar stock up to 38 mm diameter. The sub-spindle provides 5.5 kW (7.5 hp) at 7,000 RPM for back-working operations including part pickup, back-face turning, drilling, and finishing. The powerful spindle package supports aggressive cutting in stainless steel, titanium, and Inconel at the largest SYNCREX bar diameters. 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 9-axis configuration adds a B-axis milling spindle over the 38/8 layout, enabling angular milling, compound contour machining, and off-axis features that would otherwise require secondary operations. This capability is critical for complex medical implants, aerospace fittings, and hydraulic components with angled ports, cross-holes at compound angles, and contoured surfaces. Typical configurations include 24-30 tool positions combining fixed turning tools, rotary live tools, B-axis tools, and back-working stations.
The MAZATROL SmoothG CNC control brings Mazak’s conversational programming interface to the most complex Swiss-type configurations. Programming 9-axis simultaneous operations conversationally reduces the barrier for shops transitioning from conventional Swiss machines. The machine weighs approximately 4,200 kg (9,259 lb) with a footprint of roughly 3.3 x 1.6 meters. Competitors include the Citizen M32-VIII, Star SR-38, Tornos SwissDECO 36, and Tsugami SS38. New machines price between $320,000 and $450,000.

Strengths & Limitations
Strengths
- 9 axes including a B-axis milling spindle enable true 5-axis contouring on Swiss-type parts, eliminating secondary operations for compound-angle features and contoured surfaces
- 38 mm bar capacity covers the largest precision parts in the SYNCREX lineup including medical implants, hydraulic manifolds, and aerospace fittings
- 7.5 kW main spindle provides the power needed for aggressive material removal in stainless steel, titanium, and Inconel at large bar diameters
- MAZATROL SmoothG conversational programming simplifies 9-axis setup compared to traditional G-code programming on Citizen and Star platforms
- Removable guide bushing supports both Swiss mode for long slender parts and chucker mode for shorter parts with better material utilization at 38 mm bar cost
- 24-30 tool positions accommodate complex multi-feature parts with main spindle, sub-spindle, cross-working, and B-axis operations in a single cycle
Limitations
- 7,000 RPM spindle speed is the lowest in the SYNCREX range, limiting surface speed on smaller-diameter features within the 38 mm capacity envelope
- Newer entrant to Swiss-type market means limited SYNCREX production track record versus Citizen, Star, and Tornos with decades of proven performance
- B-axis milling adds programming complexity that requires operators trained in multi-axis Swiss programming beyond standard 7 or 8-axis operations
- Higher price point than the 38/7 and 38/8 models may be difficult to justify for shops whose parts do not require the B-axis contouring capability

Frequently Asked Questions
01
Base SYNCREX 38/9 configurations start around $320,000. Production-ready setups with bar feeder, parts catcher, high-pressure coolant, and full tooling complement run $380,000-$450,000. The 38/9 sits between the 38/8 ($270,000-$400,000) and the flagship 38/9X in both capability and price.
02
The 38/8 has 8 axes optimized for standard Swiss turning with cross-working and live tooling. The 38/9 adds a B-axis milling spindle for angular and contoured machining as a ninth axis. The 38/9X extends the 38/9 with additional travel, tool capacity, and enhanced B-axis capability for the most complex Swiss-type parts.
03
The Citizen M32-VIII is the established leader in larger Swiss-type machining with decades of production history but maxes out at 32 mm bar capacity. The SYNCREX 38/9 offers 38 mm capacity with 9 axes including B-axis milling and MAZATROL conversational programming. For parts requiring 33-38 mm bar or B-axis contouring, the SYNCREX 38/9 provides capabilities the M32 cannot match.
04
The B-axis milling spindle enables angular milling, compound contour machining, and off-axis features that would otherwise require secondary operations. Typical applications include medical implants with contoured bone-contact surfaces, aerospace fittings with angled port intersections, and hydraulic components with ports at compound angles.
