The VISION WIDE MS Series Portal Milling Machines are engineered for heavy-duty, large-part machining that requires exceptional stiffness and precision. They embody the typical VISION WIDE product philosophy of rigid structure and high accuracy in a bridge-type configuration. To achieve superior performance, the MS series incorporates a direct-driven X-Y transmission device coupled with a unique torque enlarger unit on the X-axis, which collectively boosts X-Y moving accuracy and offers precise control over speed and feed.

Stability and dynamic performance are ensured by a sophisticated motion system. The Z-axis employs twin hydraulic cylinders plus a pressured nitrogen accumulator balancing design, which delivers smooth and accurate feeding performance and allows the Z-axis to achieve a rapid acceleration of 0.5G. This balancing design is also critical for safety, as it helps keep a holding position in the event of a power failure. The machine structure relies on heavy-duty roller ways on the X-Y axis for high stiffness and low friction, while a high stiffness, light-weight table design facilitates high acceleration and deceleration even when loading heavy components up to 12,000 kg. Available spindle options include a 6,000 RPM 2-step gear type and high-speed direct-driven or built-in spindles up to 12,000 RPM, making the MS Series adaptable to both heavy cutting and fine finishing applications.
