The MB-3020 is a Bridge-type Double Column Milling Machine in the MB Series, renowned for its highly rigid structure and precision manufacturing, primarily achieved through the use of box ways with precision hand-scrapping on the X, Y, and Z axes. This careful construction ensures minimal friction, maximum stiffness, and superior dampening of cutting vibration for efficient and accurate cutting. The base structure-with its wide base, solid columns, and beam-is designed as full casting components, providing the best structural stiffness to maintain exceptional geometric accuracy throughout the entire 3-axis travel.

The machine offers an ample working area, with an X-axis travel of 3-100 mm and a Y-axis travel of 2-000 mm, capable of handling a maximum table load of 11-000 kg. Power is delivered by a robust spindle motor, rated at 18-5 – 22 kW continuously, driving a standard 4-000 RPM 2-step gear spindle. Precision is enhanced by a Z-axis twin hydraulic cylinder plus pressured nitrogen accumulator balancing design, which ensures smooth, accurate feeding performance and safety by maintaining the ram’s position at power failure. The MB-3020 also features efficient operations with a quick 3-second tool-to-tool change time from its side-mounted, cam-type ATC, making it a reliable workhorse for precision part manufacturing.
