Mori Seiki machining centers lead metalcutting industry in terms of both technology and original know-how. High-performance machining centers developed by concentrating the Mori Seiki wealth of knowledge and technological style.
Featured Machine:
Mori Seiki's NV4000 DCG™ To create the NV4000 DCG, Mori Seiki reexamined the very foundations of the design of vertical machining centers. By assembling 450 of the world's greatest engineering minds, new technology was created to eliminate machine vibration and the limitations it places on speed and accuracy.
Driven at the Center of Gravity (DCG™) uses twin ball screws to keep movement along the center of gravity.
Force Loop Advanced Shape (FLASH™) allows machining forces to traverse the arch-shaped column and into the bed, providing extra rigidity.
Minimum Moving Mass (M3™) uses digital analysis to determine ideal mass for improving accuracy and dynamic response without compromising strength or vibration dampening.
The combination of these innovations makes the NV4000 the most efficient vertical machining center to date. Maximum feed acceleration along the x, y and z axes is 19.4 ft/s2, 19.4 ft/s2 and 18.0 ft/s2 respectively. The maximum spindle speed of 12,000 min-1 can be reached in just 1.3 seconds. The automatic tool changer boasts a tool-to-tool changing time of just 1.0 second and chip-to-chip tool change time of only 2.8 seconds.
Along with increasing speed, Mori Seiki boosted the accuracy of the NV4000. Minimized vibration coupled with zero overhang result in extreme contouring precision and machined surface quality. Oil is circulated through a jacket surrounding the spindle to minimize thermal displacement, allowing stable machining over long periods of time.
