Overview
The Mazak SYNCREX 38/7 is the entry-level configuration in the largest SYNCREX bar capacity range, offering 38 mm (1.496 in) bar capacity with 7 axes of CNC control. This machine brings the largest Swiss-type bar capacity in the SYNCREX lineup to shops that need the 38 mm capacity but prefer the simpler 7-axis configuration for standard Swiss turning operations with lower programming complexity and setup time.
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 cutoff pickup, back-facing, and secondary drilling. The powerful spindle package handles the increased cutting forces required at 38 mm diameters across stainless steel, titanium, and Inconel. The guide bushing is removable for non-guide-bushing mode on shorter parts.
The 7-axis configuration provides the essential Swiss-type motions for main and sub-spindle turning with cross-working capability. This streamlined axis count keeps programming accessible while enabling simultaneous main and sub-spindle operations with live tooling. Typical configurations include 20-24 tool positions with fixed turning tools and live rotary tools.
The MAZATROL SmoothG CNC control provides Mazak's conversational programming for the largest SYNCREX bar capacity. The machine weighs approximately 3,800 kg (8,378 lb) with a footprint of roughly 3.1 x 1.5 meters. Competitors include the Citizen M32-VIII, Star SB-20R, Tornos SwissDECO 36, and Tsugami SS38. New machines price between $250,000 and $360,000.

Strengths & Limitations
Strengths
- 38 mm bar capacity is the largest in the SYNCREX lineup, accommodating larger medical implants, hydraulic components, automotive drivetrain parts, and industrial fittings
- 7.5 kW main spindle provides the power needed for aggressive cutting in stainless steel, titanium, and Inconel at the largest Swiss-type bar diameters
- 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 compared to traditional Swiss G-code on Citizen and Star platforms
- Removable guide bushing provides flexibility for Swiss mode or chucker mode depending on part geometry requirements
- Lower entry price than the 38/8 and 38/9X makes this the most affordable way to access 38 mm Swiss-type capability on the SYNCREX platform
Limitations
- 7-axis configuration lacks the additional cross-working and milling axes found on the 38/8, limiting simultaneous operation complexity and off-center feature capability
- 7,000 RPM spindle speed is the lowest in the SYNCREX range, limiting surface speed on smaller-diameter features within the 38 mm range
- Fewer tool positions (20-24) than high-end Swiss machines from Citizen that offer 30+ positions in this bar size class
- Newer entrant to Swiss-type market with limited SYNCREX track record compared to established Citizen, Star, and Tornos platforms with decades of production history

Frequently Asked Questions
01
Base SYNCREX 38/7 configurations start around $250,000. Production-ready setups with bar feeder, parts catcher, high-pressure coolant, and live tooling complement run $310,000-$360,000. The 7-axis model is the most affordable entry point in the 38 mm SYNCREX range.
02
The 38/8 adds an eighth axis of control, providing additional cross-working capability for more complex simultaneous operations. The 38/8 accommodates more tool positions and enables off-center milling and hexagonal machining. For standard Swiss turning with back-working at 38 mm, the 38/7 is sufficient; for complex multi-feature parts, step up to the 38/8.
03
Choose the 38/7 when your parts require bar stock between 32 mm and 38 mm diameter. If your parts fit within 25 mm or 32 mm, the smaller SYNCREX models with 8 axes provide more complex machining capability at a lower price. The 38/7 is specifically for shops that need the 38 mm capacity but do not need the complexity of 8 or 9-axis programming.
04
Yes. The guide bushing is removable, allowing the machine to operate in non-guide-bushing (chucker) mode for shorter parts. This reduces bar remnant waste and improves material utilization on parts with L/D ratios under 3:1. At 38 mm bar diameter, the material savings from non-guide-bushing mode can be significant.
