Screw Rod Lathes  Manufacturers, Traders, Suppliers

The NILES-SIMMONS N series is a closed series of CNC inclined bed lathes, graduated in five sizes from N10 to N50, designed for economical turning operations on workpieces with a swing diameter of up to 1,250 mm and a turning length of 7,500 mm. Your advantages at a glance: - Consistent machine series with tailored design solutions - High continuous accuracy with high cutting performance and long service life - Minimum non-productive times due to high accelerations and rapid traverse rates of the axes - Productivity increase through adapted process combinations - Hard turning as a substitution for the grinding process - Resource-efficient applications, environmentally friendly dry machining - Tailored automation solutions and workpiece handling

N10 * modular machine design for efficient 2- and 4-axis shaft machining or chuck part machining with pick-up spindle * high basic accuracy and thermal stability as prerequisite for hard and precision machining * prepared for automatic loading and unloading by means of portal or integrated loading device * separable work area for simultaneous 2-step machining on left and right work spindle * lowerable tailstock can be combined with counter spindle * in-feed and outfeed * automatic loading and unloading by means of gantry or integrated loading deviceProcess and post-process measuring strategies N20 * Latest machine generation for efficient 2- and 4-axis shaft machining or chuck part machining with pick-up spindle * Machine bed in composite design (Hydropol) with highest damping capacity and thermal stability * Reduced energy consumption by using energy-efficient components and consumption-optimized mechatronic assemblies * Machine also available as turn-broaching or milling machine, Extension stage as BAZ with turning-drilling-milling head and automatic tool change possible * Turning length variants up to 3000mm for long shafts * Automatic loading and unloading by means of portal when used in production lines N30 * Adjusted turning length stages up to 4500mm for flexible shaft machining with one or two tool turrets * Left and optional right turning spindle as powerful motor spindle or gear spindle with high torque also as backlash-free rotary axis * 2 independent NC-Steady rests can be used * Machine can be equipped with support * Process combination o Turning/cam form milling o Turning/pushing o Turning/brilling/milling with driven tool spindles N40 * Free access to the work area, obstacle-free crane or portal loading * left and right turning spindle as powerful gear spindle with high torque also as backlash-free rotary axis * adapted automation levels for low-operator production z.e.g. with automatic tool head change in left and right turrets * cut-to-size machine variants, e.g. for heavy roughing of railway axles N50 * heavy turning with turret or monobloc tools * internal machining with drilling sleeve * precision machining with integrated measuring concept as well as temperature and thermal response compensation
