To continue driving down cost per part, a series of lathes that provides milling capability as robust as a machining center was developed. Engineered from the viewpoint of workpieces and tools, the NL Series of lathes focuses on increasing rigidity and minimizing thermal displacement as a means of improving precision and productivity. The NL Series features 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.
