2020 HAMAI MC3VA VERTICAL MACHINING CENTERS

Technical Description

The 2020 Hamai MC3VA is a 3-axis precision vertical machining center manufactured by Hamai Co., Ltd. of Japan, a builder known for high-accuracy machine tools used in precision component manufacturing and mold applications. The MC3VA is configured as a twin-spindle machining center, featuring two independent spindles mounted on a shared column with a center distance of 17.7 inches, enabling simultaneous dual-part machining to double productive output without increasing cycle time. Each spindle is rated at 8 HP continuous and reaches a maximum speed of 8,000 RPM, accommodating a BT40/CAT40 taper tooling interface standard in the precision machining industry. Axis travels measure 29.5 inches in X, 17.7 inches in Y, and 17.7 inches in Z, supported by a 51.2-by-20.5-inch table providing adequate surface area for dual-part workholding setups. Hamai's precision-ground guideways and ballscrews are characteristic of the manufacturer's emphasis on geometric accuracy and repeatability, making the MC3VA well suited to tight-tolerance components where positional accuracy and surface finish consistency are critical. Each spindle head features a 24-position automatic tool changer, enabling complex programs across multiple features without operator intervention. The machine is controlled by a Fanuc OM CNC system, a reliable and widely supported platform in precision manufacturing environments. At approximately 13,600 pounds, the MC3VA provides substantial structural rigidity relative to its work envelope. It is particularly suited to precision job shops, mold component manufacturers, and production facilities where dual-part processing improves throughput on smaller workpieces.
