1986 OKK MCV410 VERTICAL MACHINING CENTERS

Technical Description

The 1986 OKK MCV410 is a 3-axis vertical machining center manufactured by OKK (Osaka Kiko Co., Ltd.), a Japanese precision machine tool builder. The MCV410 represents OKK's mid-size VMC production of the mid-1980s, a period when Japanese machine tool builders were establishing global standards for CNC machining center quality and reliability. The machine table measures approximately 39.4 by 25.6 inches and accommodates medium-weight workpieces. Axis travels of approximately 30 inches in X, 16.1 inches in Y, and 20.1 inches in Z define the cutting envelope for this generation. A 20 HP spindle through No. 50 ISO taper tooling reaches up to 5,000 RPM, reflecting the moderate spindle speeds common to box-way VMCs of this era that prioritized torque and rigidity over high rotational speed. Control on 1986 production units is typically a Fanuc 11M system, which provided reliable G-code execution, canned cycles, and tool length compensation appropriate for the production demands of the period. The cast iron base and column construction of OKK machines from this generation is exceptionally robust, and many MCV410 units have remained in service for decades due to the quality of Japanese manufacturing practices of the era. At approximately 11,000 to 12,700 pounds, the MCV410 is a substantial machine well suited to toolroom and job shop applications requiring dependable three-axis milling capability.
