Haas ST-15Y vs Tsugami M08SY-II
Haas Automation vs Tsugami · CNC Lathes / Turning Centers
Summary
The Haas ST-15Y and the Tsugami M08SY-II are compact Y-axis turning centers of the same size: both turn 11 in (279 mm) in diameter, take bar of 2.5 in (64 mm) on the Haas and 65 mm (2.56 in) on the Tsugami, and carry 12 tools. The difference is in the spindles and the configuration. The Tsugami M08SY-II is aimed at finishing both ends of a part in one cycle; on the Haas ST-15Y that depends on the configuration including the sub-spindle.
The Haas has the stronger main spindle, 20 hp (14.9 kW) against 7.5/11 kW, a 6,000 rpm sub-spindle against 4,500 rpm (rated 4,000 rpm), and a slightly longer turning length, 16 in (406 mm) against 380 mm (15.0 in). The Tsugami main spindle reaches 4,500 rpm (rated 4,000 rpm) against 4,000 rpm, and it is the heavier machine at 5,600 kg (12,346 lb) against 7,900 lb (3,583 kg).

Advantages
Haas ST-15Y
- 20 hp (14.9 kW) main spindle against 7.5/11 kW
- 6,000 rpm sub-spindle against 4,500 rpm (rated 4,000 rpm)
- 16 in (406 mm) turning length against 380 mm (15.0 in)
Tsugami M08SY-II
- Aimed at both-end work, so complex bar parts leave the machine finished complete
- Main spindle to 4,500 rpm (rated 4,000 rpm) against 4,000 rpm
Verdict
For steel bar parts with flats, hexes and cross holes, where the cut is mostly turning and the main spindle does the work, the Haas ST-15Y brings 20 hp (14.9 kW) against 7.5/11 kW. For valve and hydraulic bodies and other complex parts that must leave the machine finished on both ends, the Tsugami M08SY-II is the one built for the job, replacing separate turning, milling and second-operation machines.
