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

Thermo-Friendly Concept
The unique approach of "accepting temperature changes."

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.

MA-600HⅢ Thermal deformation over time:
7 µm (room temperature change: 8℃)

Note: The "actual data" referred to above represent examples, and may not be obtained due to differences in specifications, tooling, cutting condition, and others.

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 *1 (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.

    *1. Coolant suction time varies depending on the tool.

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

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)

*2. At low inertia

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.

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

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

“Sludgeless Tank” enhances stable operations (recommended option)

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

It is important to remove impurities (sludge) contained in the coolant for stable operation of the machine, and coolant tank cleaning is indispensable. The Sludgeless Tank (recommended option) efficiently collects 99% of the amount of sludge and reduces coolant contaminants. By suppressing sludge accumulation in the tank, the frequency of troublesome tank cleaning can also be drastically reduced, enabling stable operations over long runs.
