L-370II
CNC LATHE
| 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. |
|
| Headstock |  |
|
● 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.) |
|
| Rigid, Robust Tailstock | |
| L-290/M ● 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. |
