TTB-20A

Outstanding Performance of the New Era！
TTB-20 Series make a limited space can be used with more flexibility. Excellent cutting performances with its compact floor space satisfy customers' needs of heavy duty cutting.
SLANT BED CNC LATHE
●	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-20 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-20 Series can achieve maximum 20 m/min for X axis and 25 m/min for Z axis. And the servo motors adopt absolute encoders for faster and more reliable positioning.
Head Stock
●	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.
Boxway Structure
The Boxway design satisfies your rigidity needs for heavy cutting and interrupted cutting.

Servo Turret
High speed servo driven turret changes tool position within 0.2 seconds with high precision and speed.
Direct Coupled Motor
Driect coupled ballscrewtransfres energy without waste.
βP/ αP Series Motor (TTB-20C Series)
To installβP/ αPseries motor,the large low-speed torque can be obtained which satisfy customers’ diverse needs of cutting.
BMT Power Turret (TTB-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 (TTB-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.
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.
Manual/ Auto Tool Presetter(OPT)
The tool presetter shortens tool set up time and can easily measure tool wear to ensure machining accuracy.
Parts Catcher(OPT)
The parts catcher is a synchronized design for quick collection of finished product.
Product Conveyor(OPT)
The product conveyor is combined with the barfeeder, which allows the machine to perform fully automatic operations.
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.
