MB-5000HⅡ: That will enable various forms of fabrication, from mass production to variable-mix, variable-volume applications, to achieve optimum, full-scale processing at the fastest speed possible, with the MB-5000HⅡ.

Demonstration: The MB-5000HⅡ offers quick acceleration, short tool changes, and high power to improve productivity.

Aluminum Frame: High-speed machining of aluminum mass-produced parts.

Y-Strainer: Okuma's premium solution, Turning Cut, integrates turning in a machining center.

Engine Cover: Reducing not only machining time, but also the time for non-cutting processes such as tool changes.

Gear box housing: Fast machining of aluminum parts in mass production.

3D Machine View: This video presents a 3D representation of the MB-5000HⅡ.

Achieving high-speed performance in the world's fastest class

Fast machining of aluminum parts in mass production

With fast acceleration/deceleration axis feeds for shorter positioning times, high-speed B-axis rotation (table), high-speed ATC, plus high-speed hole making
— all effective toward achieving world’s fastest class level cycle times.

High-speed machining example of aluminum mass production

The cycle time became 34% less compared to the previous machine.

Reduced positioning times

With fast accel/decel axis feeds designed to reduce positioning times:

Rapid traverse acceleration (max) :

X axis: 1.0 G
Y axis: 1.1 G
Z axis: 1.0 G
Machining Time Shortening Function

MTSF shortens machining time in operations with repeated rapid traverse (G00) and cutting feed (G01) movements for parts with many drilled holes.

(The amount by which machining time is reduced will differ depending on machine setup, machined part shape, and part program.)
Reduced table indexing times
A roller gear cam mechanism is used for the 0.001-degree indexing table (Optional), and that has minimized indexing time. Fast indexing has been achieved.
- 90° indexing: 1.0 sec^*
- 180° indexing: 1.2 sec^*
*With 0.001° indexing table (Optional)
Reduced ATC times
The ATC disk magazine provides faster operations.
The farthest tool magazine indexing time possible is 5.1 seconds.
- ATC tools: 48 (No. 40 spindle)
- T-T time:
  
  0.9 sec (tool mass: 4kg or less)
  1.3 sec (tool mass: 4kg or higher)
- Farthest pot indexing:
  5.1 sec (With 48-tool magazine)

The lineup of highly rigid and highly torqued spindles: Also handles powerful cutting of steel; The lineup of spindles with roller bearings, compared to ball bearings, has higher rigidity. (Optional)
In addition to No. 40 spindles, No. 50 spindles are also available. With large-diameter side cutters and long boring bars etc, deep hole and protruding cut applications can be handled.
[Max tool length: 510 mm, max tool weight: 12 kg (No. 40 spdl), 15 kg (No. 50 spdl)]

Chip discharge designed to achieve maximum operating times: Machining chamber with accumulated chips and biting into covers — thoroughly removed; In-machine covers renewed. Flat covers are used to drastically improve chip discharge. Moreover, with simpler designs, chip accumulation and biting-in troubles have been prevented. The machine has the high durability fully capable of withstanding the long continuous runs required for mass production at maximum rapid-traverse rates and machining capacity.
