2015 OKK DGM400 VERTICAL MACHINING CENTER

Technical Description

The 2015 OKK DGM400 is a 5-axis high-speed vertical machining center manufactured by OKK (Osaka Kiko Co., Ltd.), a Japanese precision machine tool builder. The DGM400 is engineered for high-speed graphite electrode milling and die-mold cavity work, featuring a bridge-type construction that provides exceptional rigidity while accommodating the rapid traverses required for high-speed cutting. The machine table measures approximately 30.3 by 18.7 inches, providing ample workholding area for electrode blanks and medium-size mold inserts. A 30,000 RPM integral spindle motor drives small-diameter end mills at surface speeds that minimize cutting forces and tool deflection in fine detail work, while the 10 HP continuous rating delivers sufficient torque for productive material removal rates. Axis travels of 22.2 inches in X, 16.1 inches in Y, and 16.1 inches in Z, combined with the additional rotary/tilt axes, provide the five-axis interpolation needed for complex contoured surfaces in a single setup. The OKK Neomatic 635 CNC control provides high-speed look-ahead processing and smooth surface finish algorithms essential for graphite and copper electrode production. A 24-tool automatic tool changer supports unattended operation across multiple electrode profiles. Rapid traverse rates of 1,890 IPM minimize non-cutting time between features. With a machine weight of approximately 11,000 pounds, the DGM400 is a specialized high-speed platform designed for toolrooms and mold shops requiring premium surface quality and geometric accuracy on complex three-dimensional workpieces.
