- LT2000 EX with Gantry Loader OGL5
- Highly efficient, repeated machining of complex-shaped parts on 3 turrets. Long-run continuous operation is also possible with auto bar feeder and unloading systems.
Achieve ideal balance for 1-2 processes
Highly efficient machining with spindles with same capacity on left and right
Left and right spindles equipped with high accuracy integral motor/spindles make part transfer possible during spindle operation with synchronized C axis control.

Note: The chuck/cylinder used may limit machinable bar diameters.
Turrets with the same upper and lower capacity enable full process-intensive machining
V16 turrets are used on both top and bottom to handle complex shape, multi-process, high mix production. Setup change time can be shortened with permanent tool sets.

Achieve the best production system with our abundant lineup
Achieve even greater productivity and process-intensive machining by selecting specifications matched to use, such as simultaneous machining with 3 upper/lower turrets or simultaneous upper/lower Y-axis machining.
Minimize takt time with third turret (Optional)
Well-balanced cycle times achieved with simultaneous machining using upper left and right turrets and lower turret. Cycle times can be significantly shortened.
Y-axis specifications (Optional) added on all turrets
Simultaneous upper/lower Y-axis machining possible.
