The MS-2120 Portal Mill Machine is a double-column milling center from the MS Series, offering a combination of rigid structure and high precision for a wide range of machining applications, including auto parts, small car molds, and mechanical hardware. It is designed with a table dimension of 2-000 mm by 1-800 mm and can support a maximum table load of 8-000 kg. The machine provides a generous work envelope with an X-axis travel of 2-100 mm and a Y-axis travel of 2-000 mm.

The machine’s performance is secured by its advanced structural features. It utilizes heavy-duty roller ways on the X and Y axes, providing the benefits of low friction and high stiffness. The driving system incorporates a direct-driven X-Y transmission device and a torque enlarger unit on the X-axis, which work together to enhance moving accuracy and offer combined control of speed and precision. The Z-axis features twin hydraulic cylinders plus a pressured nitrogen accumulator balancing design, ensuring smooth and accurate feeding performance, allowing the Z-axis to reach 0.5G acceleration, and securing the holding position in case of a power failure. The machine’s spindle has a continuous power rating of 18.5 kW, offering a standard speed of 4-000 RPM or 6-000 RPM through a 2-step gearbox, with options for direct-driven speeds up to 12-000 RPM. Rapid traverse rates reach 24 m-min on the XY axes.
