Tongtai TMS-1800S

 CNC Machining Multi-tasking Turning Center B-axis mill-turn spindle

The TMS-1800S is engineered for highly complex part machining. Built on an FEM-optimized orthogonal structure and double-wall column design, it delivers exceptional rigidity for demanding applications. At its core, it features a zero-backlash B-axis roller cam and a high-precision cooled spindle with 0.001° positioning accuracy, ensuring stable performance during extended machining operations. With its sub-spindle configuration, the TMS-1800S enables automatic front- and back-side machining in a single setup. From fixed-angle operations and simultaneous five-axis machining to gear cutting, all processes can be completed in one clamping—eliminating repositioning errors and significantly reducing cycle times. It is the ideal solution for manufacturers seeking both maximum productivity and superior machining quality.

High-Rigidity Orthogonal Structure 

Utilizes wide-span roller-type linear guideways on all motion axes to effectively absorb cutting vibrations and maintain machining quality. The entire machine structure is optimized through FEM analysis and features a double-wall column design with an orthogonal X/Y/Z-axis layout, significantly enhancing overall rigidity and geometric accuracy. This robust structural foundation ensures excellent dynamic stability, enabling the machine to maintain outstanding performance during high-speed operation.

High-Precision B-Axis Roller Cam 

The B-axis adopts a roller cam mechanism, delivering high rigidity, zero backlash, and fast response. While maintaining exceptional turning rigidity, it also provides outstanding milling performance. It supports an ultra-wide travel range from -30° to +210° and offers 0.001° high-precision positioning, enabling highly accurate multi-surface and multi-angle machining in a single setup. This ensures consistent precision and long-term operational stability.

Machining with Main and Sub Spindles

Equipped with a sub-spindle, the machine supports automatic part transfer and reverse-side machining, enabling complete machining of both ends of the workpiece in a single setup.

This technology significantly reduces manual handling and cumulative errors caused by secondary clamping, while greatly improving machining efficiency—making it an ideal solution for high-precision, highly reliable automated production lines.

High-Precision Built-In Spindle

The built-in spindle delivers high responsiveness and incorporates a cooling system for synchronized thermal control, effectively minimizing thermal deformation and maintaining stable machining accuracy during extended operations. Paired with a CS-axis precision optical scale feedback system, it achieves ultra‑high positioning accuracy of 0.001°, enabling precise and versatile multi-angle machining for complex applications.
