Overview
The DN Solutions Puma TT 1800SY is a twin-turret, twin-spindle turning center that doubles your cutting capability by running two turrets simultaneously on a single part — or processing two parts at once. The TT designation means dual turrets (upper and lower), and the SY adds sub-spindle and Y-axis. This is a production machine built for cycle time reduction, where every second shaved off translates to real money at volume.
Both spindles run at 5,000 RPM with 22 kW (29 hp) and 208 Nm (153 ft-lb) of torque. The 8-inch chuck handles parts up to 230 mm (9 in) turning diameter and 230 mm turning length — this is purpose-built for compact, complex parts like automotive components, fittings, and connectors. Each turret carries 12 tool stations with live tooling running at 6,000 RPM, and the Y-axis provides 100 mm of off-center travel for milling operations.
Axis travels are 165 mm on X, 100 mm on Y, and 700 mm on Z with rapids hitting 20 m/min on X and 40 m/min on Z. The Z-axis rapid is notably fast at 40 m/min, reflecting the production focus — fast tool changes and minimal non-cutting time. At 8,800 kg, the machine has enough mass to handle simultaneous cutting from both turrets without vibration issues. The Fanuc control manages the twin-turret synchronization that makes simultaneous cutting possible.

Strengths & Limitations
Strengths
- Twin turrets (24 total tool stations) enable simultaneous cutting from both sides, dramatically reducing cycle times on production parts
- Matched main and sub-spindle (both 22 kW, 5,000 RPM) ensure second-operation machining doesn't bottleneck the cycle
- 6,000 RPM live tooling on both turrets provides genuine milling capability for complex features without a second machine
- 40 m/min Z-axis rapid traverse minimizes non-cutting time during tool changes and positioning moves
- Y-axis with 100 mm travel enables off-center drilling, milling, and tapping operations on both spindles
Limitations
- 230 mm (9 in) max turning diameter and length limit this machine to compact parts — not suitable for larger chucking work
- Twin-turret programming complexity requires experienced operators or strong CAM support for simultaneous operations
- 8,800 kg weight and 3.9m length take significant floor space relative to the small part size capability
- Higher acquisition cost ($250K-$350K) requires high production volumes to justify over a single-turret SY machine

Frequently Asked Questions
01
New Puma TT 1800SY machines run $250,000-$350,000 depending on options and automation. The twin-turret platform commands a significant premium over single-turret SY machines. The production-level cycle time savings justify the investment at volumes above 10,000-20,000 parts per year.
02
The TT 1300SY is the smaller platform with a 6-inch chuck and lower turning capacity, designed for very small precision components. The TT 1800SY steps up to an 8-inch chuck with 230 mm turning diameter and more spindle power, handling a wider range of compact production parts.
03
Yes. The twin-turret design enables simultaneous cutting — the upper turret can rough while the lower turret finishes, or both can work on different features at the same time. The Fanuc control handles the synchronization and collision avoidance. Simultaneous cutting can reduce cycle times by 30-50% on suitable parts.
04
The TT 1800SY doubles your tool capacity (24 vs 12 stations) and enables simultaneous cutting that a single-turret machine can't do. The trade-off is higher cost, more complex programming, and a larger footprint. For high-volume production, the TT pays for itself through cycle time reduction. For low-volume job work, a single-turret SY machine is more cost-effective.
