Higher floor space productivity with larger work envelope

Optimal travels for the large parts applications

The X-axis travel is longer and the maximum loadable workpiece size has also increased to handle a wider range of applications.

Machine structurally designed for ease of use

Good accessibility to the spindle and workpiece

● 800 mm from the operation panel to the spindle

Operation panel mounted on the left Swivel movement improves
visibility and workability

● Workpiece and operation screen XYZ directions are the same
● Operator can be close to the screen, for less fatigue

Open ceiling for setup station and workspace area

● Easy part load/unload by crane
● Lighting is good, and coolant doesn’t drop in the workspace area

Outstanding dimensional stability even for long-run machining of large workpieces

Thermo-Friendly Concept

The unique approach of “accepting temperature changes.”

Outstanding dimensional stability

Okuma’s Thermo-Friendly Concept achieves high dimensional stability not only when the room temperature changes, but also at machine startups or when machining is resumed. To stabilize thermal deformation, warming-up time is shortened and the burden of dimensional correction during machining restart is reduced.

Machine is structurally designed to achieve outstanding accuracy

● Highly rigid 3-point supported bed
Easy installation thanks to bed that does not twist. Supporting stable, high accuracy over a long period.

● Ball screw bracket
The ball screw brackets at both ends of the X-Y-Z axes are reinforced and combined for highly accurate drive and positioning.

● Ball screw cooling
X-Y-Z axes ball screw cooling and Y-axis motor bracket cooling are standard. Assuring stable accuracy during high rates of operation.

● Indexing table and pallet Highly accurate indexing table
• Standard: Curvic coupling (1 degree indexing)
• Optional: NC (0.001 degree indexing)
The pallet seating on a tapered cone achieves highly accurate positioning and excellent durability.

Productivity improved by shortening non-cutting time

Shorter tool change times are possible when using thru-spindle coolant

● Suction of excess coolant in spindle Removes residual coolant in the tool and spindle in one draw: 0.4 seconds (drill actual data). In-spindle coolant suction eliminates the need for an air blow (minimum 15 seconds) to remove residual coolant, shortening tool change time.

Coolant suction time: 0.4 seconds*1 *1. Coolant suction time varies depending on the tool.

Shorter table indexing times

Table indexing time is shortened by the SERVONAVI Rotary Axis Inertia Auto Setting function.

Table indexing time [1 degree indexing]
1.6 sec/90°*2 20% reduction (compared to previous model)

Table indexing time [0.001 degree indexing]
1.4 sec/90°*2 44% reduction (compared to previous model)

High speed operations

Rapid traverse60 m/min (X-, Y-, Z-axis)
Rapid acceleration0.7 G (max)
Tool change2.0 sec (T-T) / 3.7 sec (C-C)
/ 3.7 sec (CTC min)
Pallet change time12 sec / 13 sec

Chip discharge that maximizes uptime

With simple workspace covering and reinforced coolant applications, efficient chip discharge and long-run applications possible

Just Z-axis travel single cover and a smooth X-,Y-axis telescopic covers suppress chip accumulation. Moreover, in dry machining without coolant, washing only the lower workspace area with coolant is possible. In-machine washing prevents likely areas of chip accumulation, by cleaning away chips to maintain long-run production runs.

Chip discharge and workspace area designed to prevent chip accumulation

In-machine wash coolant: 450 L/min (18% improvement compared to previous machine)

Stronger workspace lower area wash and hinge conveyor smoothly removes large-volume coolant and accumulated chips out of the machine.

From the upper area of the workspace, a shower coolant system (option) and coolant from the X-,Y-axis telescopic covers suppress chip accumulation.

Preventing chip accumulation with smooth X-,Y-axis telescopic covers and Z-axis stainless steel single cover

Flat covers in the workspace prevent chip accumulation

Center trough design enhances large amount of chip discharge out of the machine

Out-of-machine chip discharge

Optional a lift-up chip conveyor that discharges chips to the outside of the machine, and a Sludgeless Tank (recommended option) that efficiently collects sludge are available.

“Sludgeless Tank” enhances stable operations
(recommended option)

Suppresses sludge accumulation in the coolant tank. Dramatically reducing troublesome tank cleaning work

Coolant sludge removal, less environmental impact when disposing coolant

Sludge removal rate 99% (for castings) 97% (for aluminum)

No tank cleaning required for two years!

Unidirectional coolant flow in the Sludgeless Tank also suppresses coolant deterioration due to stagnation. Coolant replacement frequency is greatly reduced, and the environmental impact is less when coolant disposal amounts are also reduced.

Keeping spindle tapers clean

The three filtration devices in the Sludgeless Tank and coolant suction inside the spindle reduce dirt on the spindle taper and lessen defective machining.

Compact—integrated with the through-spindle coolant tank

The thru-spindle coolant tank is integrated, and the coolant heater/cooler (option) can be mounted on the tank, saving space.
