Okuma MB-56V VERTICAL MACHINING CENTER

Technical Description

The Okuma MB-56V is a vertical machining center featuring a rigid double-column structure designed for precision manufacturing across aerospace, automotive, medical, and die/mold applications. The machine accommodates workpieces up to 1,980 lbs on its 51.18" x 17.72" table with optional support for index and rotary tables. The standard configuration includes a CAT #40 taper spindle operating at 8,000 rpm with 15 hp output, expandable to 30 hp with optional high-speed spindles reaching 15,000 rpm or higher. Three linear axes deliver 41.34" (X), 22.05" (Y), and 18.11" (Z) travel distances, with rapid traverse rates of 1,575 ipm on X-Y axes and uniform 787 mm/min cutting feedrates across all axes. The machine incorporates a 48-position automatic tool changer with 1.2-second tool change time, minimizing non-cutting cycles. Advanced thermal control ensures dimensional stability during extended production runs, while the ergonomic front-access design maximizes productivity within minimal floor space. Optional configurations include high-power spindles (up to 40 hp), alternative taper sizes (CAT #50), and pallet changer systems for unmanned machining. The MB-56V achieves exceptional accuracy with thermal compensation technology, producing flatness tolerances of 3 micrometers and roundness tolerances of 1.65 micrometers on aluminum components. This versatile platform processes materials from aluminum to hardened steel and titanium, making it suitable for both small and large production runs requiring high-precision complex part manufacturing.
