LT2000 EX with Gantry Loader OGL5
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
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.

Bar dia Standard spindle ø51mm ø65mm*2
Big-Bore spindle ø65mm*1 ø80mm
  • *1. Left spindle only
  • *2. Up to ø69 mm is possible with 10-inch chuck.
  • 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.

Rapid traverse X axis: 30 m/min, Z axis: 40 m/min
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.

Spec variations
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.
Example of spool
45% shorter
Y-axis specifications (Optional) added on all turrets
Simultaneous upper/lower Y-axis machining possible.
