Machine Structure

High Rigidity Body Structure For Heavy-duty Machining

 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

Z-Axis High Performance Motor
Z-axis is equipped with high performance feed motor for better travel ability.
Z-axis rapid traverse rate: 30 m/min [1,181 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

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

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.

 5 Tailstock

NL 2000/2500/3000 are equipped with heavy-duty programmable tailstock with built-in spindle quill as standard to ensure high rigidity and machining quality.
