Overview
The Tsugami M08SY-II is the most capable machine in Tsugami's M-series turret lathe family, combining an 8-inch main chuck, 6-inch sub-spindle, Y-axis, live tooling, and C-axis into a single platform. It's the top of the line for shops that want maximum mill-turn capability from a compact turret lathe.
Capacity reaches 280 mm (11.02 in) on chuck work and 65 mm (2.56 in) bar stock. The main spindle runs 200-4,500 RPM with a 7.5/11 kW (10/14.8 HP) motor, while the 6-inch sub-spindle also delivers 200-4,500 RPM powered by a 5.5/7.5 kW (7.45/10 HP) motor. Live tooling spins at 5,000 RPM, and the 12-station turret serves both spindles. The FANUC 0i-TF control handles all the axis coordination.
The Y-axis provides ±50 mm of cross travel for off-center features, and rapid traverse rates are 24 m/min on X, 12 m/min on Y, 27 m/min on Z, and 30 m/min on the sub-spindle A-axis. At 5,900 kg (13,007 lb) and 2,470 x 1,850 x 1,930 mm, it's the heaviest machine in the M-series. Box-way construction on X and Y axes combined with linear roller guide ways on Z provide the right mix of rigidity and speed.
The M08SY-II also features 300 PSI through-coolant capability, which is critical for deep-hole drilling and working with gummy materials like stainless and titanium. This machine is built for shops that want one machine to do the work of three, producing complete parts with front turning, back turning, off-center milling, and cross-drilling in a single uninterrupted cycle.

Strengths & Limitations
Strengths
- Most complete mill-turn capability in the M-series with sub-spindle, Y-axis, live tooling, and C-axis
- 5,000 RPM live tooling and 300 PSI through-coolant enable effective milling and deep-hole drilling
- Box-way construction on X and Y axes provides exceptional rigidity for stable milling operations
- 5,900 kg mass delivers industry-leading vibration damping for a compact turret lathe
- 8" main and 6" sub chucks handle a wide range of medium-sized mill-turn components
- FANUC 0i-TF control is proven, reliable, and widely supported
- Single-setup part completion eliminates multiple operations and improves accuracy
Limitations
- Highest cost in the M-series lineup, requiring high utilization to justify the investment
- 12-station turret shared between two spindles, live tools, and all operations can limit tool count
- Y-axis 12 m/min rapid is slower than other axes, adding time on Y-heavy programs
- Machine complexity demands skilled programmers and maintenance personnel
- 5,900 kg weight requires adequate foundation and makes relocation difficult

Frequently Asked Questions
01
New M08SY-II machines typically price in the $200,000-$280,000 range depending on options, tooling packages, and accessories. This is the top-spec machine in Tsugami's M-series and includes features like Y-axis, sub-spindle, live tooling, and 300 PSI through-coolant. Used units from recent years may appear in the $120,000-$180,000 range.
02
Both are sub-spindle Y-axis turret lathes, but they come from different design philosophies. The Tsugami emphasizes precision, thermal stability, and compact footprint. The Haas offers more raw power and a larger work envelope at a lower price point. The Tsugami's box-way construction and precision grinding give it an edge on tolerance-critical parts. The Haas is typically easier to source and service in North America.
03
The 300 PSI through-coolant system delivers high-pressure coolant directly through the cutting tool, which is essential for deep-hole drilling, chip evacuation in blind holes, and maintaining tool life when machining gummy materials like 316 stainless steel or titanium. It significantly improves hole quality and tool life compared to flood coolant alone.
04
Yes, the FANUC 0i-TF control supports simultaneous X, Y, Z, and C axis interpolation for complex milled contours. This enables features like helical milling, contoured pockets, and complex surface profiles on turned parts. Most modern CAM systems can generate toolpaths for this configuration.
05
Absolutely. Pair it with a bar feeder for 65 mm bar stock and you've got a fully automated mill-turn production cell. The sub-spindle picks up parts before cutoff, back-end operations complete automatically, and finished parts drop into the parts catcher. It's ideal for high-volume production of complete mill-turn parts from bar.
