1996 OKK MCV660 VERTICAL MACHINING CENTERS

Technical Description

The 1996 OKK MCV660 is a 3-axis vertical machining center manufactured by OKK (Osaka Kiko Co., Ltd.), a Japanese precision machine tool builder. The MCV660 is a large-format VMC designed for heavy-duty milling of large mold blocks, die plates, and structural components. The machine table measures approximately 66.9 by 26 inches, accommodating large workpieces across the generous X-axis stroke of 59.8 inches, complemented by 26 inches in both Y and Z axes. A 25 HP spindle through No. 50 BT50 or CAT50 taper tooling reaches a maximum of 4,500 RPM on standard configurations, prioritizing torque and rigidity for steel and cast iron work over high-speed finishing capability. The OKK Neomatic 635, a Mitsubishi-based CNC system used widely across OKK's production of the 1990s, provides reliable ISO G-code programming, canned cycles, and rigid tapping. Box-way or wide linear guideway construction delivers the stiffness and vibration damping essential for heavy interrupted cuts. With overall machine dimensions of approximately 167 by 142 by 133 inches and a weight of approximately 26,400 to 26,500 pounds, the MCV660 is a substantial production machine that reflects OKK's Japanese manufacturing philosophy of building structural mass and rigidity as the foundation for long-term dimensional accuracy and reliability in demanding production environments.
