Chicago, Illinois, September 27, 2007 – Mori Seiki has announced the inclusion of a 20-station tool turret on
two new models in its NL Series of CNC lathes. Available on the NL1500 and NL2000 machines, the 20-
station turret allows the machining of more complex parts on the NL Series.
Since the new 20-station turret can hold up to 20 tools, it is perfectly suited for jobs with a high number of
processes that made them impossible to complete with just 12 tools. By using the high-rigidity, compact
tooling system found in Mori Seiki’s NT Series and NZ Series, the company has increased the machining ability
and versatility of the NL Series to match those of machining centers.
Like all machines in the series, the new models of the NL1500 and NL2000 feature a milling motor inside the
turret directly coupled to the milling tool. This patent-pending design drastically reduces the transmission
losses and inherent vibration associated with competing designs, which use a series of gears and belts to
provide a milling feature. When compared to conventional models, the direct-coupled milling motor reduces
tool spindle acceleration time by 2/3 and diminishes vibration and noise by 1/2.
To further reduce vibration while cutting, machines in the NL Series employ a rigid triangle structure in the
bed, spindle and tailstock. The box way construction further reduces vibration and increases rigidity, resulting
in greater cutting depth and feed rates, and reducing cycle times by up to 50%.
The machines feature a digital tailstock in which a servo drive provides all movement. This allows position and
thrust to be controlled from the operation screen rather than manually setting them. Additionally, by adjusting
the tailstock from within the part program, setup time can be reduced by up to 50%.
The NL1500 and NL2000 further increase accuracy by minimizing the effects of heat on machining operations.
Specially placed coverings isolate heat radiating from the oil controller and hydraulic unit, redirecting heat to
the outside of the machine. Heat transfer devices also control the heat emanating from the headstock and
servomotors. The design of the turret with a direct-coupled milling motor also reduces heat generation to
1/15 of the conventional model.
