Overview
The Hyundai WIA LM1600TT Series is a twin-turret, twin-spindle CNC turning center available in multiple configurations: LM1600TTS (twin turret, sub-spindle), LM1600TTMS (twin turret, milling, sub-spindle), and LM1600TTSY (twin turret, sub-spindle, Y-axis). With a 6-inch main chuck and 6-inch sub-spindle, twin 12-station turrets, and a built-in spindle reaching 6,000 RPM, the LM1600TT is engineered for maximum throughput on small-diameter complex parts.
The built-in main spindle delivers 15/11 kW (20/15 hp) at up to 6,000 RPM with 208/140 N.m of torque. The built-in design eliminates belt vibration and enables smoother surface finishes at high RPM -- critical for the small-diameter precision parts this machine targets. The sub-spindle matches at 6,000 RPM for full-speed backworking capability. Both spindles use 6-inch chucks, providing symmetric capability for main and sub operations.
The twin turret configuration with 2 x 12 tool stations (24 total) is the LM1600TT's primary productivity advantage. Both turrets can operate simultaneously -- one on the main spindle and one on the sub-spindle, or both on the same spindle for balanced turning. LM guideways deliver the positioning speed needed for short-cycle production, with rapid traverse rates of 20/20/40/40/40 m/min across the five axes. The TTMS variant adds 5,000 RPM live milling to the upper turret, while the TTSY variant adds both live milling and Y-axis capability (100 mm travel) for off-center operations.
New LM1600TT Series machines price between $160,000 and $250,000 depending on configuration. The series competes with the existing Hyundai WIA LM1800TTSY (8-inch class), Nakamura-Tome SC-100/150, and Star SR-38. For high-volume production of small, complex parts in automotive, medical, and precision component manufacturing, the LM1600TT delivers twin-turret simultaneous machining in a compact 6-inch platform.

Strengths & Limitations
Strengths
- 6,000 RPM built-in spindle provides the highest speed in Hyundai WIA's lathe lineup, enabling maximum surface speed on small-diameter precision parts
- Twin turret with 24 total tool stations allows simultaneous cutting on both spindles, reducing cycle times by 30-50% versus single-turret machines
- Built-in spindle design eliminates belt vibration for superior surface finish quality at high RPM on precision components
- 40 m/min rapid traverse on Z-axes is exceptionally fast, minimizing non-cutting time in short-cycle production programs
- TTSY variant with Y-axis adds off-center milling capability for complete done-in-one production of complex parts
- Symmetric 6-inch main and sub chucks provide equal capability for front and back operations without workholding compromise
Limitations
- 6-inch chuck limits the machine to small-diameter parts only -- shops with larger part diameters need the LM1800TTSY or L-SY series
- 15 kW spindle power is modest for heavy roughing -- the machine is optimized for small parts rather than aggressive material removal
- Twin-turret programming complexity requires experienced programmers and multi-channel CAM software
- LM guides prioritize speed over vibration damping -- not ideal for heavy interrupted cuts on rough castings

Frequently Asked Questions
01
Hyundai WIA's distributors quote the LM1600TT per variant, and the variant is the single biggest driver: TTS is turning only, TTMS adds 5,000 rpm live tooling to the upper turret, and TTSY adds the 100 mm Y-axis on top of that. Beyond the variant, the bar feeder, chucks and collets, and holders for 24 turret stations across two turrets accumulate quickly on a twin-turret machine. Multi-channel CAM licensing for twin-turret programming is a real cost too, and it is not part of the machine quote.
02
TTS = Twin Turret + Sub-spindle (turning only). TTMS = Twin Turret + Milling + Sub-spindle (adds 5,000 RPM live tooling to upper turret). TTSY = Twin Turret + Sub-spindle + Y-axis (adds both live tooling and Y-axis for off-center milling). Each step up adds capability and cost.
03
The LM1600TT has 6-inch chucks (vs. 8-inch), faster spindle (6,000 vs. 5,000 RPM), and faster Z-axis rapids (40 vs. 30 m/min). The LM1800TTSY handles larger parts with more spindle power (18.5 kW vs. 15 kW). Choose the LM1600TT for small parts at maximum speed; the LM1800TTSY for larger parts requiring more power.
04
Multi-channel CAM is essential: GibbsCAM (strong multi-turret support), ESPRIT (Hexagon), Mastercam Mill-Turn, and SolidCAM all support twin-turret synchronization. The Fanuc 31i-B control handles the multi-channel G-code these CAM systems generate for coordinating two turrets and two spindles simultaneously.
