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.

  • High-speed machining example of aluminum mass production
  • MB-5000HⅡ
  • 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 table indexing times
  • 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)
    Reduced ATC times
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.
