OKUMA ES V4020 VERTICAL MACHINING CENTER

Technical Description

The OKUMA ES-V4020 Vertical Machining Center is a high-performance CNC machine designed for precision milling operations. It features a robust table size of 47.24" x 20.08" with a maximum table load capacity of 1,500 lbs, supporting heavy-duty workpieces. The machine offers generous travel ranges: 40" on the X-axis, 20" on the Y-axis, and 20" on the Z-axis, enabling versatile part machining. The spindle nose to table top distance ranges from 7.8" to 27.8", accommodating various tooling setups. The spindle delivers speeds from 40 to 8,000 RPM with a CT 40 taper, ensuring compatibility with a wide range of cutting tools. The main motor provides 15 HP (10 min.), 10 HP (30 min.), and 7.5 HP (continuous) output, balancing power and endurance. Equipped with a 20-position automatic tool changer (ATC), the machine streamlines tool changes for increased productivity. Rapid traverse rates reach 984 IPM across all axes, while the cutting feed rate is 314 IPM, supporting efficient material removal. The machine occupies a floor space of 110" x 90" x 117" and weighs approximately 8,800 lbs, reflecting its sturdy construction. It is controlled by the OSP10M CNC system, known for reliability and ease of use. Additionally, the machine includes a 4th axis rotary table, expanding its capability for complex multi-axis machining tasks.
