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).

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)

Cycle time minimized with high-speed loading and powerful milling

Machine structure for high-speed loading and powerful machining

Workpiece load/unload time has been reduced to 4 seconds, and machining-to-part transport line takt time has been minimized. Moving component (headstock, turret) centers of gravity have also been positioned over sturdy slide guides.
Powerful, accurate machining has been achieved with the best machine structure possible for mass production.

Productivity improved with significantly stronger spindle

The spindles are faster and more accurate with integral motor/spindle drives. The milling tool spindles also have higher output of 7.1 kW, increasing torque to 1.25 times that of the previous machine and doubling end millling capacity to 65 cm3/min. Process-intensive mill/turn operations have become possible.

The shortest line takt times with a high-speed loader

During workpiece load/unload, the headstock moves to that position. The loader can enter the machine regardless of turret position.
In addition, with servo-driven hand rotation and faster speeds of all movements, workpiece load/unload time of 4 seconds* has been achieved.

* Does not include upper door open/close time.
The load/unload time of 4 seconds is actual data; different operating conditions may require more time.

Long-run, stable machining with high accuracy

Split bed for high-quality machining

A split construction is used for the bed. Transmission of vibration during cutting is inhibited by separating the right and left sides.

This is also effective when high surface roughness is required.

Ideal for mass production of parts up to ø250 mm

The 2SP-2500H can take on loader-delivered workpieces up to ø250 mm in size, and achieves minimum takt times for mass-produced parts.
With M specifications, the milling tool spindle capacity is strengthened, enabling a greater diversity of process-intensive machining.

Process-intensive machining with powerful milling

More powerful, can use greater number of tools

Turning, drilling, end milling all done on a single machine to accommodate a wide range of applications. A much more powerful milling tool spindle than on previous machines enables more powerful cutting and a wider range of process-intensive machining. The turret minimizes interference with neighboring tools so that millling tools can be attached in all 12 locations.

Applications from turning to milling can be done with a single chucking, reducing the work in progress storage space and between process waiting times. Chucking error during workpiece installation can also be eliminated for higher machining accuracies.

Innovative shop floor productivity in many types of production

High productivity with 2 roles by 1 machine (2SP-V760EX, 2SP-V920EX)

The 2-spindle spec 2SP-V760EX, 2SP-V920EX combines a standard R (right) machine and reverse structure L (left) machine and is operated with a single controller.

This gives the maximum productivity with the minimum floor space by shortening lead times and cutting down on intermediate work in progress.

The separated right-left structure also enables stable machining that is unaffected by the machining vibration of the other spindle.

• Compact lines that minimize robot travel can be built.

Stable accuracy

• Powerful machining of medium to large cubic and odd-shaped workpieces
• The box-type base and column make a highly dependable, highly rigid structure
• Workpiece deadweight pressed on vertical chuck helps stabilize machining

Highly rigid construction A strong, square column is positioned on a large, rigid base with good damping properties, and a highly rigid, reliable structure with wide box ways on both the X and Z axes is used. Smooth, stable feeds are achieved during low- to high-speed cutting with a counterbalance not affected by feed rate changes.	Turret Large 12-station turret has adequate space for easy and also permanently set tooling arrangements. The large-diameter coupling enables high accuracy indexing and powerful heavy-duty cutting with strong hydraulic clamps.

Stable machining achieved with workpiece deadweight sitting tight on chuck

The workpiece deadweight itself helps provide a firm seat on the chuck reference surface. Without excessive workpiece restraint, distortion and pressure marks can be prevented to achieve highly accurate machining of thin to large and heavy workpieces.
Manual part load/unload, without holding it, is also easy for irregularly shaped workpieces that require clamps.

Powerful machining

• Using motors with wide constant-power ranges
• Headstock with flange construction to minimize effects of thermal deformation and vibration

Spindle

• The headstock has a flange construction and is solidly fixed to a box-type base. This minimizes the effects of thermal deformation and vibration.
• A powerful motor with a wide constant-power range is used for the spindle. Combining this with a big bore spindle enables powerful heavy-duty cutting.
