High-performance vertical machining center debuts


During its Innovation Days event in mid-May 2006 at the company's Chicago Technical Center, Mori Seiki debuted its most advanced vertical machining center, the NV6000 DCG, in North America. Among NV6000 DCG's attributes is the ability to contour more accurately and produce "significantly less" residual vibration than earlier machines. Mori Seiki stresses the machining center's "unrelenting quality, accuracy, safety, and productivity."

Up time and ease of service received prime attention at every stage of design with the NV Series. The latest computer design techniques and dynamic analysis was applied to reduce machine footprint and weight, while improving overall machine rigidity and metal cutting capability, according to Mori Seiki. Permanent and disposable parts count also was minimized.

A variety of other machines on exhibit at Innovation Days showed Mori Seiki's depth of products. One noteworthy machine in the lineup was NZ-S1500, a new 2-turret shaft lathe making its regional debut. NZ-S1500 employs a symmetrical design in which the two turrets are aligned with the spindle and mounted on the vertical bed. This layout is said to increase productivity and also reduces heating effects, improving accuracy during continuous machining. Thermal displacement is held to under
