Overview
The DN Solutions PUMA TT 2500 SY is the fully-loaded variant of the TT 2500 platform, adding Y-axis capability to the already impressive twin-turret, twin-spindle architecture. With 120 mm (5 in) of Y-axis travel, a 10-inch chuck, and 26 kW (35 hp) on both spindles, this is DN Solutions' answer to shops that need to produce complex mid-size parts complete in a single cycle without any secondary operations.
Both the main and sub-spindle deliver 26 kW (35 hp) with 433 Nm (319 ft-lb) of torque at 3,500 RPM. That's matched power on both ends with enough grunt to hog material in 4140, stainless, and Inconel without breaking a sweat. The 10-inch chuck swings parts up to 390 mm (15 in) in diameter with 350 mm (14 in) of turning length. Each turret carries 12 stations with 5,000 RPM live tooling.
The Y-axis provides 120 mm (5 in) of cross-travel — that's 20 mm more than the smaller TT models, which makes a difference when you're milling wider flats or cutting deeper keyways. X-axis travel is 255 mm, Z gives you 800 mm. Rapids run 20 m/min on X and 24 m/min on Z.
At 12,700 kg (27,999 lb), this machine sits on a rock-solid foundation that keeps vibration in check during simultaneous twin-turret cutting. The FANUC multi-path control coordinates everything: synchronized spindle handoff, collision avoidance, and multi-axis interpolation for complex milling operations. For shops that have outgrown the TT 1800/2100 size class and need Y-axis milling on bigger parts, the TT 2500 SY fills the gap between compact multi-taskers and full-size mill-turn machines.

Strengths & Limitations
Strengths
- 120 mm Y-axis travel is 20% more than smaller TT models, enabling wider flats and deeper keyways on mid-size parts
- 433 Nm (319 ft-lb) matched torque on both spindles handles heavy roughing in tough materials without hesitation
- Twin 12-station turrets with 5,000 RPM live tooling plus Y-axis delivers true mill-turn capability
- 390 mm turning diameter covers a wide range of mid-size production parts the smaller TTs can't reach
- 12,700 kg mass provides excellent rigidity for aggressive simultaneous twin-turret cutting
- Done-in-one production eliminates secondary operations, WIP inventory, and inter-machine handling
Limitations
- Top-of-range pricing makes this a serious capital investment requiring consistent high-volume production to justify
- 24 m/min Z-axis rapids are slower than smaller TT models, impacting cycle time on long-travel programs
- 3,500 RPM spindle ceiling limits high-speed finishing on small-diameter aluminum parts
- 12,700 kg weight and 4+ meter length demand substantial floor space and foundation preparation
- Complex multi-path programming with Y-axis requires experienced operators and longer setup times for new jobs

Frequently Asked Questions
01
The SY variant typically runs $30,000-$50,000 more than the MS due to the Y-axis drive, linear guide, and associated servo system. The premium is worth it if your parts have off-center features; if they don't, save the money and go with the MS.
02
The TT 2500 SY's 120 mm Y-axis travel is generous for a twin-turret lathe. The smaller TT 1800/2100 models only offer 100 mm. Dedicated mill-turn machines like the Mazak Integrex series may offer more, but they're also significantly more expensive and have a larger footprint.
03
The Y-axis is typically associated with one turret at a time during Y-axis milling operations. Both turrets can still cut simultaneously for standard turning operations while the Y-axis is in use on one turret. The FANUC control manages the coordination and collision avoidance.
04
It runs a FANUC multi-path control with iHMI touchscreen interface. The multi-path architecture manages independent programming for each turret, synchronized spindle handoff, Y-axis interpolation, and collision detection. It's the same FANUC ecosystem used across DN Solutions' turning center lineup.
05
Twin-turret machines are primarily production machines. If you're running batches of 50+ identical complex parts regularly, the TT 2500 SY will pay for itself through cycle time reduction. For one-off and small-batch work, a single-turret Y-axis lathe like the PUMA 2600SY offers more flexibility at a lower investment.
