2001 OKUMA MA550VB VERTICAL MACHINING CENTER

Technical Description

The 2001 Okuma MA550VB is a 3-axis vertical machining center from Okuma's MA-VB series, featuring a CAT50 Big-Plus taper spindle and a large worktable suited for heavy-duty aerospace, mold, and die applications. The MA550VB is built on a double-column bridge frame with Thermo-Friendly Concept (TFC) thermal management and linear guideway construction for high-speed, high-accuracy performance. The worktable measures 51.18" x 22.05" (1,300 x 560 mm) with a maximum table load of approximately 2,200 lbs. Axis travels are 51.18" in X, 22.05" in Y, and 22.05" in Z, with rapid traverse of 1,181 IPM (30 m/min). The gear-head or built-in spindle motor delivers approximately 30 HP (22 kW) continuous with a maximum speed of 6,000 RPM, providing high torque for aggressive stock removal in steel and cast iron. A 32-tool arm-type ATC performs chip-to-chip changes in approximately 4 seconds. The Okuma OSP-U100M control features G-code and conversational programming, Okuma's Collision Avoidance System (CAS) for crash prevention, servo drives with absolute encoders, and standard Ethernet connectivity. Overall machine footprint is approximately 126" x 112" (L x W) with a height of 114" and a weight of approximately 29,960 lbs. The MA550VB is well suited for production environments requiring a reliable large-table VMC platform with decades of OEM support.
