Mori Seiki's original technology, DCG® (Driven at the Center of Gravity). This controls vibration, the main factor preventing high speed and high precision, by pushing structural components at their center of gravity with a twin drive using 2 ball screws.
Restricting vibration
For positioning, machines with DCG® virtually eliminate vibration, while machines without DCG® continue to vibrate for a long time. It controls the rotational vibration which appears at every acceleration start point, and which is proportional to the distance between the drive point and the center of gravity. This prevents deterioration of the quality of the machined surface. achining by advanced.

Outstanding acceleration performance
Machining by advanced DCG® technology generates little vibration at the beginning of acceleration, and it is possible to accelerate with maximum force from the very start.
Improved roundness
DCG® also minimizes the vibration that comes from changes in the direction of travel. This significantly improves roundness in circle cutting.
Table-in-Table Construction
The Table-in-Table Construction, in which the C-axis table is placed within the B-axis table, has been adopted. Its highly rigid structure allows stable machining accuracy.
Table rigidity
We used dynamic analysis to design a table with even higher rigidity.
The 4 guideways are located diagonally from each other, so they distort symmetrically in response to the heat generated y high-speed travel. This means that the center stays in the same position, offering high-speed, high-precision feed.
