Great Performance Beyond Your Imagination!  
TTB-25 Series has strong boxway structure with wide range spindle motor, and performs efficient cutting ability. Best choice for who are looking for machine with excellent performance and reasonable price!
Widen span boxway structure  
Widen span and Thicken goove to enhance the stability to meet optimal cutting performance. Slant bed structure design to achieve optimal turning performance and force conduction.
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 TTB-25 series also offers optional rear type chip conveyor.
Servo motors are directly coupled to ballscrew with high pretension to minimize backlash and thermal distortion and improve machining accuracy.
The TTB-25 Series can achieve maximum 20 m/min for X axis and 20 m/min for Z axis. And the servo motors adopt absolute encoders for faster and more reliable positioning.
Head Stock  ttb
The spindle has labyrinths to prevent moisture and dust.
The spindle is supported by NN double-row bearings combined with thrust ball bearing.
The belt adopt V belt to enhance horsepower transmission.
Servo Turret  ttb
The high speed servo drive turret changes tool position directly with high precision and speed.


Direct Coupled Motor ttb-25
Direct coupled ballscrew transfers energy without waste.
Wide range spindle motor ttb-25
Low rpm and high torque motor characteristic satisfy customers' diversified working needs.
BMT Power Turret ttb-25
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.
Manual/ Hydraulic Steady Rest (OPT) ttb-25
The steady rest is ideal for long bar turning application and can be manually adjusted to reduce the vibration and maintain machining stability.


Manual/ Auto Tool Presetter(OPT) ttb-25
The tool presetter shortens tool set up time and can easily measure tool wear to ensure machining accuracy.
Load Monitor Function(OPT) ttb-25
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.
Inverter Hydraulic Unit(OPT) ttb-25
To install inverter hydraulic unit can save more than 35% power consumption. It's not only environmental protection, but also can save you much production cost!


Upright Control Panel ttb-25
The agronomical control panel can be swiveled 90゚ for easier operator access.
Front Discharge Coolant Tank
(Side type chip conveyor)
Coolant tank can be removed in the front for simple access to clean and maintain.
Tool Cabinet  
Tool cabinet under the control panel offers extra storage space for operator to use for storing tools.
