OKUMA MC-3VA VERTICAL MACHINING CENTER

Technical Description

This vertical spindle CNC machining center features a robust 39.3" x 15.7" work table with 1100 lbs. load capacity, providing ample workspace for mid-sized production runs. The machine delivers 22.8" X-axis, 14.1" Y-axis, and 19.6" Z-axis travel, accommodating diverse workpiece geometries and complex multi-axis machining operations. The #40 spindle taper with variable speed ranging from 60 to 6000 RPM enables versatile material processing from rigid steel boring to precision finishing in aluminum and composites. Rapid traverse rates of 630 IPM on X/Y axes and 472 IPM on Z-axis ensure efficient non-cutting movements between operations. The dual-speed 10/7.5 HP spindle motor delivers consistent torque across the speed range, supporting up to 20 tools with maximum diameter of 3.5" and length of 11.8". The adjustable spindle nose height (3.9"–23.6" to table top) accommodates varied part heights and setups. Weighing 9920 lbs. with overall dimensions of 133.2" L x 108" W x 93.6" H, this machine provides industrial-grade rigidity and thermal stability essential for maintaining positioning accuracy during extended production cycles. The machine's substantial construction and comprehensive specifications suit applications in tool and die making, aerospace components, and precision metal fabrication requiring reliable repeatability and surface finish quality.
