Machine Structure

High Rigidity Body Structure For Heavy-duty Machining

NL4000-6000_Basic_Information
 1 One-Piece Casting Bed  

One-piece 45-degree slant bed made out of Meehanite cast iron, which has superb vibration absorption characteristics, provides rigid foundation for all machine components. Such design endures long-term machining accuracy and consistency.

 2 Turcite Precise Scraping Carriage
carriage

Z-Axis High Performance Motor
Z-axis is equipped with high performance feed motor for better travel ability.
Z-axis rapid traverse rate: 20 m/min [787 ipm]

Wide box guideways and Carriage
Hexahedral design and wide box guideways, machined from one piece casting, promote heavy duty machining.
Wide carriage promotes less vibration and allows high precision machining.

 3 Main Spindle
NL4000-6000_main_spindle

Double row cylindrical roller bearings in the front and back, coupled with angular thrust bearing, ensure high rigidity for heavy cutting and excellent surface finishes

 4 Turret
NL2000_Turret_cut

Heavy-duty turret driven by high torque AC servo motor ensures rapid rotation, correct positioning and fast indexing time. Also the design features large diameter Curvic coupling ensure accurate positioning and strong clamping power.
