Heavy Duty CNC Precision Lathe Machines  

Optimal Structure Design High Precision! High Rigidity!
● The main structure castings of the machine are manufactured from high quality cast iron, stress relieved for better stability.
● One-piece Cast iron base features increased rigidity and superior machining stability.

● The headstock is ruggedly constructed to resist heavy duty turning with excellent heat dissipation performance. Equipped with 3,000/4,200 RPM precision spindle.

● The spindle has a labyrinth circulation design to prevent moisture and dust from entering into the spindle.

CAD/CAE Computer Analysis

● The machine structure is designed by CAD computer software.

● Advanced CAE computer software is also applied for optimal structure design. In addition, this software also provides analysis of dynamic, static stress and thermal stress.

Box ways on X and Z-axis

● Rapid traverse on X-axis is 20M/min(L-290/M)

● Rapid traverse on Z-axis is 25M/min(L-290/M)

● Box ways are hardened and precision ground.

High Speed, Precision Turret  

● V8 hydraulic turret(STD.)
● V12 hydraulic turret(OPT.)
● V8 NC turret (OPT.)

Rigid, Robust Tailstock  
● Tailstock quill diameter 60mm, MT NO.4 (STD.)
● Tailstock quill diameter 90mm, MT NO.5 (OPT.)
L-370 II
● Tailstock quill diameter 80mm,MT NO.5 (STD.)
Top Quality Electronic Components  
● The electronic parts and connectors meet the rigorous military specifications and industrial specifications. These top quality electronic parts provide extremely stable control performance and long service life.
● Outstanding control circuit layout combines with modular design to simplify maintenance, while ensuring control performance at all times.
Oil Fluid Separation Device  
● The coolant system is designed with oil fluid separation to prevent coolant from deterioration or odor.
