1985 OKUMA CADET V4020 VERTICAL MACHINING CENTER

Technical Description

The 1985 Okuma CADET V4020 is a 3-axis vertical machining center manufactured by Okuma Corporation, a Japanese precision machine tool builder and one of the industry's longest-established VMC producers. The CADET V4020 is one of the most widely deployed VMC models in North American manufacturing history, valued for its exceptional reliability, ease of operation, and consistent dimensional accuracy across decades of production service. The machine table measures approximately 47 by 20 inches with axis travels of 40 inches in X, 20 inches in Y, and 20 inches in Z, providing a practical work envelope for a wide range of medium to large prismatic workpieces. A 15 HP spindle through CAT40 taper tooling reaches 8,000 RPM, delivering reliable performance for steel, cast iron, aluminum, and non-ferrous machining. The maximum table load of 1,100 pounds and a 20-station automatic tool changer support versatile production setups. This early production unit runs the Okuma OSP5000M control, an earlier generation of Okuma's proprietary operating system that established the foundation for decades of Okuma CNC development. Overall machine dimensions of approximately 150 by 92 by 99 inches and a weight of approximately 11,000 pounds reflect the solid cast iron construction underlying the CADET's reputation for longevity. The CADET V4020 remains one of the most sought-after used VMC platforms in the North American market.
