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

Reduced positioning timesWith fast accel/decel axis feeds designed to reduce positioning times. |
Machining Time Shortening FunctionMTSF shortens machining time in operations with repeated rapid traverse (G00) and cutting feed (G01) movements for parts with many drilled holes. |
Reduced table indexing timesA 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.
*With 0.001° indexing table (Optional)
|
Reduced ATC timesThe ATC disk magazine provides faster operations.

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.

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.
