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.
Box-in-Box construction
The Box-in-Box design, which supports the saddle from both sides, guides and drives the moving parts by its center of gravity in a more balanced manner.
Twin drivePushing at the center of gravity of a moving object using two ball screws controls vibration, which is the greatest factor preventing high speed and precision. |

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.
Transmitting the drive power directly to the rotary axes without using gears eliminates backlash. Compared with conventional worm gear systems, this dramatically improves transmission efficiency and offers high-speed feed. And Mori Seiki makes them in-house, so if they ever do break down, we can fix them quickly, significantly reducing recovery time.
