Many types of machining with the flexibility of 4 axes
Huge reduction in machining time with simultaneous 4-axis machining on upper and lower turrets
In other words, simultaneous OD/OD or ID/OD operations drastically reduce cycle times. In addition with optional turnaround stand and/or a steadyrest attached to the lower turret—the possibilities are endless.
Turning long shafts with a steadyrest—without chatter
A steadyrest (optional) mounted on the lower turret does provide steady workpiece support. With an NC programmed upper turret and simultaneous control, long shafts will always be supported near the cutting point.
Balanced cutting for highly efficient turning of long workpieces
With balanced turning, tool passes can be reduced by a half. Cycle times are also reduced considerably, and chatter-free.
Powerful machining and rapid movements mean shorter cycle times
High-performance simultaneous (heavy) turning with power to spare (Actual data)
Achieve the best production system with our wide-ranging lineup
Complete multitasking with Y-axis functions
One chuck machining even with irregularly shaped workpieces
A variety of milling operations can be accommodated with high-accuracy, wide-range Y-axis travel using a double slide system. Achieves complete multitasking with a single chucking (MY specifications).
| LU3000 EX | LU4000 EX | |
| Y-axis-travel | 120 mm (+70 to −50) | 140 mm (+70 to −70) |
| Y-axis rapid traverse | 12.5 m/min | 12.5 m/min |
Sub-spindle for integrated front/back (1 machine) operations
With a sub-spindle, front and back machining can be done on a single machine. Since machining of both ends can be completed on one machine, workpiece storage space and post-process machines are unnecessary. (LU3000 EX only)
