Milltronics USA, Inc. MB20 VERTICAL MACHINING CENTER

Technical Description

The Milltronics MB20 is a 4-axis vertical machining center designed for precision metalworking applications. It features a 54" × 16" work table with a maximum workpiece capacity of 2,500 pounds, accommodating medium to large-scale components. The machine is equipped with an ISO-40 spindle taper operating at speeds up to 4,000 RPM, powered by a 7.5 HP motor with an optional 10 HP upgrade for demanding operations. The three linear axes provide substantial travel distances: 40" on the X-axis, 20" on the Y-axis, and 24" on the Z-axis, enabling machining of complex geometries. Rapid traverse speeds reach 500 IPM across all axes, while programmable feed rates up to 300 IPM ensure efficient material removal. The machine utilizes manual tool changing with a quill depth of 6 inches for additional versatility. The rigid, heavily ribbed cast-iron construction eliminates weldments, providing structural stability and thermal consistency essential for holding tight tolerances. A selectable high-torque backgear with 8:1 gear reduction enhances low-speed cutting capabilities for tough materials like steel and aluminum. Suitable for producing precision components including gears, brackets, and complex molds, the MB20 combines advanced CNC technology with robust mechanical design, making it ideal for job shops and production environments requiring reliable, high-precision vertical machining.
