Okuma MILLAC 800VH VERTICAL MACHINING CENTER

Technical Description

The Okuma MILLAC 800VH is a high-performance 5-axis vertical machining center designed for precision and efficiency in complex part production. Featuring a robust box-type bed and wide sliding surfaces, the machine delivers exceptional rigidity and stability, minimizing vibration and ensuring accuracy during high-speed operations. The table measures 31.5 x 31.5 inches and supports workpieces up to 2,205 lbs, making it suitable for large and heavy components. The vertical spindle utilizes a Big Plus CAT #50 taper, capable of reaching speeds up to 10,000 RPM, with a 30 hp (30-minute rating) motor for powerful cutting performance. The machine is equipped with an 80-station automatic tool changer, enabling rapid tool changes in just 0.4 seconds, and a standard 2-pallet changer (expandable to 6) for increased productivity and reduced setup times. Axis travels are 40.16 inches in X, Y, and Z, with a maximum feed rate of 472 ipm and rapid traverse speeds of 1,181 ipm on all linear axes. The A-axis offers 150° of rotation, supporting multi-face machining in a single setup to improve part accuracy and reduce re-fixturing. The MILLAC 800VH is controlled by Okuma’s OSP CNC system, ensuring reliable operation and advanced programming capabilities. With its combination of speed, rigidity, and versatility, this machining center is ideal for demanding applications in aerospace, automotive, and mold manufacturing industries.
