Performance beyond Comparison!  
Strong casting and the perfect boxway structure provides excellent cutting capacity for TTB-20MW Series. Sub-spindle with Milling function and Y-axis can satisfy customers' multiple needs.
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-20MW Series also offers optional rear type chip conveyor.
To make sure the usage life of Y-axis ballscrew will get longer, there are three bearings on Y-axis ballscrew to enhance the support for pressure from top.
The TTB-20MW Series can achieve maximum 20 m/min for X axis and 25m/min for Z axis. And the servo motors adopt absolute encoders for faster and more reliable positioning.
Spindle 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 reinforce the spindle radial cutting capacity and avoid the belt strength damage bearings.
The belt adopt V belt to enhance horsepower transmission.


Sub-spindle ttb
One-piece transmission base for sub-spindle, getting rid of the design that sub-spindle motor is fixed on sub-spindle box to strengthen the overall rigidity and increase the maintain convenience. Collocating with power turret can complete a multiple processes in one procedure and upgrade working efficiency!
True Y axis ttb
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.
BMT Power Turret ttb
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.
Widen Boxways ttb
Increase bed track thickness about 30% which upgrade the machining affordability and transmissibility.


Inverter Hydraulic Unit ttb
To install inverter hydraulic unit can save more than 35% power consumption. It not only can achieve environmental protection, but also can save much production cost!
Load Monitor Function(OPT) ttb
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.
Manual/ Auto Tool Presetter(OPT) ttb
The tool presetter shortens tool set up time and can easily measure tool wear to ensure machining accuracy.
Workpiece Pusher Device(OPT) ttb
Push out workpiece from sub-spindle automatically can not only save the time for taking out workpiece without manpower, but also increase working efficiency.


Parts Catcher(OPT) ttb
The parts catcher is a synchronized design for quick collection of finished product.
Product Conveyor(OPT) ttb
The product conveyor is combined with the barfeeder, which allows the machine to perform fully automatic operations.
Barfeeder(OPT) ttb
Automatic feeding system can replace traditional artificial operating, substantial saving labor requirement.
Upright Control Panel ttb
The ergonomical 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.
Lubrication Unit ttb
To make the daily maintenance easier, we put the lubrication unit at right side of machine without cover.
Hydraulic Unit ttb
Gather up hydraulic units at the ear side for easy access on daily maintenance.
