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.

High-efficiency machining from simultaneous 4-axis turning

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.

Prevents chatter with steadyrest support
Balanced cutting prevents chatter during machining of long workpieces

Powerful machining and rapid movements mean shorter cycle times

High-performance simultaneous (heavy) turning with power to spare (Actual data)

Note: The “actual data” referred to above represent examples, and may not be obtained due to differences in specifications, environmental conditions during measurement, tooling, cutting, and other conditions.

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)
