Extreme Turning for the New Era!

TTL-Series offers high productivity and high accuracy performance through exceptional cutting capability and parts finish. The TTL-Series is your best choice for ultra-performance turning center. With Y axis function, TTL-Series can reach your needs for higher level and various cutting.

High Efficiency / High Accuracy

  • The one piece cast base incorporates FEM analysis to achieve its optimal ribbing and structure to further enhance machine rigidity and stability.
  • The 30゚ slant bed design has low center of gravity for easier swarf management and better ergonomic design.  The TTL-series also offers optional rear discharge chip conveyor.
  • Servo motors are directly coupled to ballscrew with high pretension to minimize backlash and thermal distortion and improve machining accuracy.
  • TTL-Series incorporates high quality linear guide system offering better accuracy, higher speed and lower friction than boxed way.  The TTL-Series can achieve maximum 30m/min axial rapid feed in both X and Z axis.

Head Stock

The spindle has labyrinths to prevents moisture and dust. The spindle is supported by NN double-row bearings combined with thrust ball bearing.


Hydraulic Turret (STD)/ Servo Turret (OPT)

Low noise and high torque DANFOSS hydraulic system is used to enhance the turret clamping force as well as station change time.
High speed servo driven turret changes tool position within 0.3 seconds with high precision and speed.


Direct Drive Spindle

Direct coupled ballscrew transfers energy without waste.


BMT Power Turret (TTL-20M/MY Series)

The highly rigid BMT turret has large torque output and stronger tool locking mechanism to handle heavier cutting conditions while improving tool interference. The BMT turret is ideal for heavy turning and milling applications.


True Y-Axis (TTL-20MY Series)

The true linear Y-axis can make operation more easily. Compare to fake Y-axis, it can provide great straightness, and also ensure excellent positioning accuracy. To satisfy high precision cutting needs.


Manual Tailstock

Highly rigid tailstock structure and hydraulic tailstock center reduces cutting vibration.
The tailstock can be easily positioned through manual connection with turret.


Manual/ Auto Tool Presetter(OPT)

The tool presetter shortens tool set up time and can easily measure tool wear to ensure machining accuracy.


Load Monitor Function(OPT)

FANUC control system: Extra load monitor function to control tooling working to axial loading value, which can notice tool consumption in advance and reduce loss rate of production efficiently.


Rear Type Chip Conveyor(OPT)

The optional rear discharge chip conveyor reduces valuable shop floor space and allows you to centralize your chip removal system.


Upright Control Panel

The agronomical control panel can be swiveled 90˚ for easier operator access.


Front Discharge Coolant Tank

Coolant tank can be removed in the front simple access to clean and maintain.

Ergonomically Designed Coolant

Ergonomically designed for easy machine set up and parts loading and unloading.

Tool Cabinet

Tool cabinet under the control panel offers extra storage space for operator to use for storing tools.
