OKUMA MC-4020 VERTICAL MACHINING CENTER

This CNC machining center features a robust 3-axis configuration with travel capacities of 40" on the X axis, 20" on the Y axis, and 17.7" on the Z axis. The table provides a working surface measuring 48" by 20" and supports a load capacity of up to 1,500 lbs, enabling the handling of sizable and heavy workpieces. Rapid traverse rates reach 1417 IPM on the X and Y axes and 1181 IPM on the Z axis, with the maximum feed rate across all axes capped at 1181 IPM, ensuring efficient and precise material removal for a wide variety of machining tasks. The spindle assembly includes a CAT-40 taper spindle with a power rating of 20 HP, capable of speeds ranging from 50 to 8,000 RPM, offering flexibility for multiple cutting and finishing operations. The distance from spindle face to table surface adjusts from 6.3" to 24", accommodating different workpiece heights. Tool management is facilitated by an automatic tool changer with a capacity for 32 tools, streamlining production by minimizing manual tool changes. Electrically, the machine operates on a 220V, three-phase, 60 Hz power supply. Its physical footprint measures approximately 114" by 111" with a height of 104" and a substantial machine weight of 16,000 lbs, reflecting a solid and stable build that reduces vibrations and supports machining accuracy. This combination of travel, spindle power, and feed capabilities makes it suitable for high-precision industrial milling applications involving complex, heavy, or large-format components.
