DMG Mori Seiki NZX 4000 suits heavy turning

A twin-turret turning centre, designated NZX 4000, has been introduced by DMG Mori Seiki for machining long workpieces with large diameters, such as crankshafts for marine engines or oil pipeline applications. The trapezoidal, deformation-resistant machine bed and wide, flat guideways in all axes are primarily responsible for the rigid structure.

The top 12-station, 11/7.5 kW turret features an optional ±70 mm Y-axis and a direct drive, allowing the turning centre to achieve a milling performance equivalent to that of an SK 40 machining centre, says DMG Mori Seiki. The beltless, gear-driven main spindle is rated at 37/30 kW (30 minutes/constant).

The maximum turning diameter is 660 mm, while the distance between centres can be either 1, 2 or 3 m. Rapid traverse rates in X and Z are 20 and 24 m/min respectively, while control is provided by DMG Mori Seiki's ERGOline control with the Industry 4.0-complaint CELOS or MAPPS from Mitsubishi.
