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.
