Okuma MILLAC 1000VH VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a 39.37" x 39.37" table capable of handling workpieces up to 4,400 lbs, ideal for heavy-duty machining. It utilizes a vertical spindle with a BIG-PLUS CAT #50 taper, offering superior rigidity and precision through simultaneous taper and flange face contact, which reduces deflection and improves tool life and accuracy. The spindle delivers 30 HP (30-minute rating) with a top speed of 6,000 RPM, optionally up to 10,000 RPM, supporting a wide range of machining applications requiring high power and speed. Equipped with a 40-tool Automatic Tool Changer (ATC) standard, expandable to 120 tools, it achieves rapid 8-second tool changes and 16 seconds chip-to-chip cycle times to optimize productivity. The system includes a standard pallet changer with two pallets, expandable to six, facilitating continuous operation and efficient workpiece handling. The machine offers 5-axis capability (X, Y, Z linear axes plus 2 rotary axes) with travels of 64.96" (X), 51.18" (Y), and 39.37" (Z), and a 150° rotary axis, delivering versatile complex part machining. Maximum feed rates reach 393 inches/min with rapid traverses of up to 945 inches/min, enabling fast, precise positioning. This combination of high rigidity BIG-PLUS spindle technology, extensive machining envelope, high horsepower, and large tool capacity makes this machining center suitable for demanding aerospace, automotive, and heavy machinery manufacturing where precision, speed, and durability are essential.
