Go to technical specs

The TB series of Tongtai's CNC lathes has a saddle with 60 degree slant design provides high rigidity structure. With symmetrical saddle design for better air circulation, it decreases the chance of heat distortion. Modular structure design for spindle module, turret module, tailstock and sub-spindle module to achieve the multi-tasking applications purpose and create the best investment. 

The preloaded ball screw reduces thermal distortion and ensures the machine's continuous performance and precision.
