Okuma 800VH HORIZONTAL MACHINING CENTER

Technical Description

The 2007 Okuma Millac 800VH is a high-performance 5-axis horizontal machining center engineered for precision and versatility in complex multi-plane machining applications. It features substantial travel capacities of 40.15 inches along the X, Y, and Z axes, enabling machining of large workpieces with high accuracy. The worktable measures 31.49 by 31.49 inches and supports a maximum load capacity of 2,200 lbs, facilitating heavy-duty machining tasks. Its spindle operates from 100 to 10,000 RPM with a No. 50 taper, powered by a 40 hp motor that provides consistent torque and speed for a wide range of materials and cutting conditions. The spindle has a swivel angle of 150 degrees, allowing flexible orientation for multi-sided machining in a single setup, reducing the need for re-fixturing and improving overall part accuracy. Indexing precision is exceptionally high, with a Curvic coupling orientation angle accuracy of 5 degrees and numerical control (NC) arbitrary indexing accuracy down to 0.001 degrees, enabling intricate and detailed machining operations. The vertical distance from spindle nose to pallet top ranges from -3.94 to 35.22 inches, while horizontal reach extends up to 46.05 inches to the pallet top, providing great accessibility. The machine’s rigid box-type bed construction, wide rectangular sliding surfaces, and large pre-tensioned ball screws ensure superior machining stability and repeatability. Rapid traverse rates along the axes reach up to 1,181 inches per minute, supporting efficient cycle times and productivity. Overall, the Okuma Millac 800VH combines robust mechanical design, precise multi-axis control, and flexible spindle configuration to meet demanding production requirements in aerospace, automotive, and general manufacturing industries.
