The MN-4023 dash MN-4030 is a high-efficiency model in the MN Series of Double Column Milling Machines, specifically designed to handle large workpieces requiring complex, 5-face function and multi-angle cutting. The machine is built with a characteristic rigid structure and high precision for demanding operations. A key design feature is the use of roller ways on both the X and Y axes, significantly boosting the dynamic accuracy and overall speed of the 3-axis rapid traverse. The structure includes a solid beam with a big cross-section and a wide base supported by 3 roller sliding ways to strengthen stiffness across the Y-travel and improve dynamic load capacity.

The machine offers a substantial working envelope, with an X-axis travel of 4-100 mm and a Y-axis travel of either 2-300 mm or 3-000 mm, resting on a table capable of holding up to 16-000 kg. The box structure of the headstock, equipped with 6 guiding roller blocks, provides outstanding stiffness, minimizing interference between the spindle and the workpiece, which is critical for complete 5-face cutting. Power is delivered by a robust spindle motor rated at 18-5-22 kW, with a standard 2-step gear spindle speed of 4-000 RPM. This efficiency is compounded by high rapid traverse speeds of up to 18 m-min on the XY-axes, maximizing throughput for large part manufacturing.
