2006 Mori-Seiki NL2500/700 CNC Turning Center

The Mori-Seiki NL2500/700 is a slant-bed CNC turning center with a reputation for rigidity and thermal stability that has made it a staple in production job shops cutting steel, aluminum, and tougher alloys. This 2006 unit pairs a 10" hydraulic chuck and 3" bar capacity with a 4,000 RPM spindle, 27.5" distance between centers, and a 14" maximum cutting diameter across a 27" turning length. The 12-station single turret delivers full live tooling capability with integrated C-axis indexing, turning routine bar work into single-setup turned-and-milled parts. A programmable hydraulic tailstock with live center handles longer shaft work, while box-way construction across the slant bed gives the damping characteristics serious cutting demands. Stepped up from Mori-Seiki's earlier SL-25 and SL-253 platforms, the NL2500/700 was a generational rewrite — not a refresh. The NL series introduced redesigned box-way construction with improved thermal symmetry, a modernized control architecture, and faster rapid traverse rates than the SL-253 it replaced. Live-tooling integration also stepped up: where the SL series treated milling tools as an add-on, the NL's turret was engineered for integrated live tooling and C-axis interpolation from the ground up, opening the door to true turn-mill workflows. For buyers comparing a clean SL-25 or SL-253 against this NL2500/700, the NL is the meaningful upgrade — more rigid, more thermally stable, and more capable of single-setup production — at a used-market price that finally puts a true turn-mill platform inside reach of a one- or two-cell shop.
