CNC Milling Machine LK-S600/S800 With 0.003mm Positioning Precision
HT300 Class Cast Iron Construction: The machine frame is made of high-quality HT300 class cast iron, offering exceptional stability, durability, and vibration damping for smooth, precise milling operations.
High-Rigidity Linear Guideways: The 3 axes are equipped with wide, high-rigidity linear guideways, ensuring superior support and minimal deflection during high-speed operations, which results in improved precision and reliability.
Large Pre-Stretched Ball Screws: The 3 axes feature large pre-stretched ball screws, which enhance the machine’s rigidity and reduce thermal deformation, ensuring long-term precision and accuracy during heavy-duty milling.
Slant Disc Type Tool Magazine: Equipped with a Slant Disc type tool magazine offering 21-tool/16-tool capacity (depending on the model), it allows for rapid tool changes, improving productivity and reducing downtime in multi-tool operations.
Fast Tool Changing: The machine’s tool magazine is designed for fast tool changes, optimizing cycle times and enabling efficient transitions between various milling tasks.
Precision Performance: With a positioning accuracy of 0.003mm and repeatable positioning accuracy of 0.003mm, the machine guarantees consistent, high-precision results, even in complex milling operations.
