The MF-4000 Bridge Type Milling Machine is specifically designed to provide a combination of heavy cutting and precision cutting with superior acceleration-deceleration control, making it the best choice for medium-to-large parts and mold machining. Its foundational rigidity comes from a solid casting structure and a unique 65-degree slant beam design with three sliding ways, which offers robust support to the headstock and enhances heavy cutting performance. All three axes feature box ways that are meticulously hand-scrapped to guarantee low friction, high stiffness, and maintain excellent dynamic level accuracy. The machine provides a generous work envelope with an X-axis travel of 4-200 mm and a table size of 4-200 mm by 2-050 mm, supporting a maximum load of 13-000 kg. Precision is ensured through a direct-driven device on the Y-Z axis transmission using large servo motors, while the X-axis employs a gear reducer to boost driving torque. To maintain consistent geometric accuracy and prevent thermal deformation during continuous operation, the machine is equipped with an independent cooling device for the 3-axis ball screws and separated oil coolers for the spindle. The standard setup includes a 4-000 RPM 2-step gear spindle and a rapid traverse rate of 12 m/min on all three axes.
