Mass production turning centres introduced in an attractive and modern design.
Tongtai’s CNC Lathes have been widely popular because of their high reliability and high cost-performance rate. Now, Tongtai has launched a new CNC Lathe series – TMT 2000 Series – that has twin spindles and two individual machining areas. The turrets and spindles are designed in parallel to each other. This design allows components, which need two machining processes, to be finished on one machine.
Moreover, by adding a gantry type robot on this model it not only improves the utilisation of the floor space but also decreases labour costs. Depending on the cycle time required (mostly, the cycle time of turning processes of automotive small parts is within 60 sec), a single robot arm or twin robot arms can be added to increase automatic production efficiency.
The Tongtai TMT 2000 Series are state-of-the-art, high-precision CNC turning centers cast from Meehanite iron. They are loaded with high tech features not found on any comparable machines. Features such as a 75 degree mono-block slant bed for excellent rigidity, chip flow and unparalleled ergonomics are included.
In addition, the optional true linear (perpendicular) Y-axis leads to simplified programming while high power synchronised spindles provide superior acceleration and deceleration times. Two servo driven turrets provide high speed indexing. The optional live turret with the rigid BMT-65 tool system with available Y-axis on the upper turret adds productivity and reduces cycle times.
Both precision spindles are built using precision double row roller bearings in conjunction with angular contact ball bearings for high rigidity and accuracy. The spindle quill inner and outer linings are precision ground for fit with the spindle, thus ensuring extreme concentricity and accuracy.
The main 4500 rpm spindle with 64mm bar capacity is driven by a 15kW high torque motor which provides power and unsurpassed acceleration while the synchronous sub-spindle has 18,5kW, 6000 rpm and a 50mm bar capacity. Both spindles feature an optional full contouring Cs axis.
Other machine specifications include a pitch of the two spindles of 440mm, maximum swing diametre of 210mm, maximum turning diametre of 210mm and turning length of 145mm.
