Makino V77 #50 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust working table measuring 55.1 inches in length and 27.6 inches in width, capable of supporting workpieces up to 5,500 lbs. The machine operates with a vertical spindle equipped with a standard #50 taper, offering an optional upgrade to an HSK-A100 taper for enhanced tooling compatibility. The spindle achieves a maximum rotational speed of 12,000 RPM, with an optional high-speed variant reaching 18,000 RPM, powered by a 25 HP motor rated for 30-minute operation and an optional 23 HP motor. The tool handling system includes an automatic tool changer (ATC) with a capacity of 30 tools, optionally expandable to 60 tools, enabling efficient tool changes within 5 seconds to reduce cycle times. The machining center operates on three axes (X, Y, Z) with travels of 47.2 inches, 27.6 inches, and 25.6 inches respectively, all capable of rapid traverse speeds up to 787 inches per minute, supporting high-speed machining and feed rates. The machine is designed without a U axis or pallet changer, focusing on 3-axis milling operations. The combination of a heavy-duty large table, powerful spindle, and fast tool change system makes this vertical machining center suited for heavy and precise milling tasks requiring high rigidity, accuracy, and productivity. Its specifications support machining of large and heavy parts with high dimensional accuracy and efficient workflow in automotive, aerospace, or heavy equipment manufacturing environments.
