1992 HAMAI MC6VA VERTICAL MACHINING CENTERS

Technical Description

The 1992 Hamai MC6VA is a 3-axis precision vertical machining center built by Hamai Co., Ltd. of Japan, representing the larger platform in the manufacturer's MC-VA series of high-accuracy vertical machining centers. The MC6VA provides substantially greater work envelope than the MC3VA, with axis travels of 49.2 inches in X, 25.6 inches in Y, and 21.7 inches in Z, accommodating larger precision components and mold bases that exceed the capacity of the smaller MC3VA configuration. The machine's 70.9-by-35.0-inch table offers generous support for large workpieces and multi-part fixturing setups. Spindle speed reaches a maximum of 4,000 RPM, reflecting the emphasis on torque and rigidity appropriate for precision cutting in harder materials and larger-diameter tooling common in this machine's class. As with other Hamai machines of this era, the MC6VA employs precision-ground guideways and ballscrews, high-accuracy spindle bearings, and thermally compensated structural components characteristic of the manufacturer's precision machining philosophy. The machine is controlled by a Fanuc Series O-M CNC system, one of the most widely supported and long-lived control platforms in the global machine tool industry, ensuring broad G-code compatibility and available support resources. At approximately 25,794 pounds, the MC6VA provides the structural mass associated with high-rigidity precision machining at this work envelope size. As a 1992 machine, it represents Hamai's precision engineering standards of that era and is well suited for facilities with existing Fanuc O-M programming experience requiring a larger-format precision VMC.
