Okuma MILLAC 853PF-5X VERTICAL MACHINING CENTER

This vertical machining center features a large worktable measuring 126" x 33.47" capable of supporting workpieces up to 6,600 lbs, enabling the machining of heavy, large components. It is equipped with a vertical spindle featuring a #60 taper and a top speed of 12,000 RPM, powered by a 60 HP motor rated for 30 minutes, with an optional upgrade to 75 HP, providing robust cutting power for demanding milling operations. The machine supports 5-axis simultaneous machining with travels of 120" (X), 33.46" (Y), 27.56" (Z), and rotary axes A and B each with ±70° rotation for complex contouring and multitasking capabilities. The tool management system includes a 30-tool automatic tool changer (ATC), with a 9-second tool change time and a 16-second chip-to-chip time, optimizing production efficiency. A 2-pallet changer is available as an option for continuous operation and quick setup changes. Rapid traverse rates of 1,181 inches per minute on linear axes ensure fast positioning, while feed rate capability reaches up to 945 inches per minute. This heavy-duty, high-precision machining center is designed for versatile industrial applications requiring strong spindle performance, large workpiece handling, and complex multi-axis machining. It integrates advanced tooling, high rigidity, and substantial travel ranges to deliver precision milling for large parts and heavy production workloads.
