CNC Lathes & Machining Centers

Used Okuma MA-550: Sell or Buy at Auction

Okuma is a premium Japanese machine tool builder known for high-precision lathes, grinding machines, and machining centers. The Okuma OSP control system is proprietary and highly regarded for its user-friendly interface and thermal compensation technology. Okuma machines are common in aerospace, automotive, and precision manufacturing.

The Okuma MA-550V is a large-capacity, three-axis vertical machining center built for heavy, oversized work. It pairs a long worktable of roughly 1,300 by 560 mm and about 51 inches of X travel with a #50-taper (CAT-50) gear-driven spindle, all run through Okuma's proprietary OSP control. The gear-head #50 spindle is built for low-end torque rather than high rpm, so it holds up to large-diameter cuts in tool steel, cast iron, and other tough materials, and the long table carries big plates, dies, molds, and structural parts that a standard #40 vertical cannot. This is the machine die and mold shops, heavy job shops, and large-part manufacturers reach for when a workpiece is simply too big or too heavy for a typical VMC. The OSP control has a loyal following among experienced machinists, and a well-maintained MA-550V holds accuracy over long production runs, so it draws active bidding whenever KD Auctions lists one. Reaching our 500,000+ industry contacts surfaces the shops and dealers already running Okuma iron who know exactly what a #50-taper OSP machine is worth. At auction it tends to bring the most when its tooling is cataloged and sold with it: the #50 tool holders, any 4th-axis rotary table or fixturing, vises, and workholding.
