OKUMA VH-40 VERTICAL MACHINING CENTER

Technical Description

This high-performance 5-axis CNC machining center offers extensive travel ranges with 22.05 inches on the X-axis, 17.72 inches on both Y and Z axes, and full rotary motion via a B-axis with ±90° tilt and a C-axis capable of 360° rotation, enabling complex multi-sided machining in a single setup. The machine supports a maximum table load of 551 lbs, making it suitable for heavy-duty workpieces. It features a robust 15 HP spindle motor with a speed of 8,000 RPM and a BT-40 spindle taper, ensuring high torque and precision for demanding milling operations. The automatic tool changer (ATC) has a capacity of 30 tools, allowing for efficient, uninterrupted production. Cutting feed rates reach up to 394 inches per minute (IPM), while rapid traverse speeds achieve 1181 IPM, significantly reducing non-cutting time and boosting overall productivity. The combination of high-speed spindle, generous axis travel, and advanced rotary capabilities makes this machine ideal for intricate aerospace, automotive, and mold components, as well as high-precision industrial parts. Its rigid construction and high dynamic performance ensure consistent accuracy and surface finish across a wide range of materials, including metals, plastics, and composites.
