Overview
The Hyundai WIA LM2200TTSYY/TTSYYC is a twin-turret, twin-spindle CNC turning center with dual Y-axes, representing Hyundai WIA's most versatile twin-turret configuration. The TTSYY variant features 8-inch main and sub chucks at 4,500 RPM, while the TTSYYC steps up to a 10-inch main chuck at 3,500 RPM with an 8-inch sub. The dual Y-axis architecture — Y1 on the upper turret and Y2 on the lower turret — enables off-center milling on both turrets simultaneously, a capability not available on standard TTSY machines.
The TTSYY features a belt-driven spindle delivering 18.5/15 kW (25/20 hp) at 4,500 RPM with 206/125 N.m of torque through an 8-inch main chuck. The TTSYYC increases the main chuck to 10 inches at 3,500 RPM with 286/214 N.m of torque for larger-diameter work. Both variants use dual 12-station turrets (24 total tool stations) with 5,000 RPM live milling capability and 20/32 mm tooling.
The dual Y-axis configuration with travel of 100 mm on both Y1 and Y2 axes is the machine's key differentiator. While standard TTSY machines only have Y-axis on the upper turret, the TTSYY/TTSYYC provides Y-axis on both, enabling simultaneous off-center milling operations on both spindles. Axis travels of X1/Y1/Z1/X2/Y2/Z2/ZB = 165/100/700/165/100/700/730 mm with rapid traverse of 20/10/36/20/10/36/36 m/min provide the work envelope for complex multi-operation programs.
New LM2200TTSYY/TTSYYC machines price between $220,000 and $320,000. The series competes with the Nakamura-Tome NTRX-300 and DMG MORI CLX 450 TC in the dual-Y twin-turret segment. For shops machining complex parts requiring off-center milling on both front and back operations simultaneously, the TTSYY/TTSYYC provides unmatched flexibility in the 8-10 inch chuck class.

Strengths & Limitations
Strengths
- Dual Y-axes on both upper and lower turrets enable simultaneous off-center milling on front and back operations
- 24 total tool stations with live milling on both turrets handle the most complex multi-operation parts
- TTSYYC variant with 10-inch main chuck handles larger workpieces while maintaining dual-Y versatility
- Twin-turret simultaneous machining reduces cycle times by 30-50% compared to single-turret alternatives
- 36 m/min rapid traverse on Z-axes provides good positioning speed for multi-operation production programs
- LM guide construction optimized for production speed and accuracy on complex small-to-medium parts
Limitations
- Dual-Y twin-turret programming is among the most complex CNC programming, requiring specialized CAM software and expert operators
- 230 mm max turning diameter limits the machine to small-to-medium diameter parts despite 8-10 inch chuck capacity
- Belt-driven spindle is less smooth at high RPM than the built-in spindle used in the LM1800TT
- High investment ($220K-$320K) requires clear production volume justification for the dual-Y capability

Frequently Asked Questions
01
TTSYY: 8-inch main and sub chucks, 4,500 RPM, 206 N.m torque. TTSYYC: 10-inch main chuck with 8-inch sub, 3,500 RPM, 286 N.m torque. The TTSYYC handles larger-diameter parts with more torque at the cost of some spindle speed. Both have identical dual Y-axis and twin-turret configurations.
02
A standard TTSY has Y-axis only on the upper turret. The TTSYY/TTSYYC has Y-axis on both turrets. This means the lower turret can also perform off-center milling, cross-drilling, and tapping — either on the main spindle or sub-spindle. This enables simultaneous off-center milling on both ends of a part, cutting cycle time on complex components.
03
The TTSYY with 8-inch chucks starts around $220,000-$270,000. The TTSYYC with 10-inch main chuck reaches $270,000-$320,000. The dual-Y capability adds approximately $40,000-$60,000 over an equivalent single-Y TTSY configuration.
04
Advanced multi-channel CAM is essential: GibbsCAM, ESPRIT (Hexagon), and SolidCAM support dual-Y twin-turret configurations. The Fanuc 31i-B control manages the multi-channel synchronization, but the CAM system must properly handle 7+ simultaneous axes across two turrets and two spindles with independent Y-axes.
