1997 OKK KCV500 VERTICAL MACHINING CENTERS

Technical Description

The 1997 OKK KCV500 is a 3-axis vertical machining center manufactured by OKK (Osaka Kiko Co., Ltd.), a Japanese precision machine tool builder. The KCV500 is a large-format VMC built on a box-way construction that delivers the rigidity required for heavy-duty milling in ferrous materials. The machine table measures approximately 50 by 25.2 inches and accommodates workpieces up to the table load rating, providing a generous work envelope for medium to large prismatic parts, fixtures, and mold bases. Axis travels of 42 inches in X, 21 inches in Y, and 21 inches in Z define the cutting envelope. A 30 HP spindle drives No. 50 CAT taper tooling at up to 6,000 RPM, providing the torque and rigidity characteristic of OKK's Japanese manufacturing philosophy favoring structural stiffness over high spindle speeds. A 30-tool automatic tool changer supports complex multi-operation programs. The OKK Neomatic M520-ME CNC control, a Mitsubishi-based system used on OKK machines of this era, provides ISO G-code programming, canned cycles, rigid tapping, and helical interpolation. Box-way guideways provide high damping capacity and resistance to cutting shock loads, making the KCV500 well suited to steel roughing, heavy face milling, and large-part finishing operations. The 1997 build year places this machine in OKK's period of peak domestic Japanese production quality before the restructuring of the late 1990s machine tool industry.
