1996 OKK MCV820 VERTICAL MACHINING CENTERS

Technical Description

The 1996 OKK MCV820 is a 3-axis vertical machining center manufactured by OKK (Osaka Kiko Co., Ltd.), a Japanese precision machine tool builder. The MCV820 occupies the large-format segment of OKK's vertical machining lineup, with a table measuring approximately 78.7 by 32.3 inches that supports heavy workpieces and multi-station fixturing for large mold bases, die plates, and structural components. Axis travels of 63 inches in X, 32.3 inches in Y, and 28.4 inches in Z provide a substantial three-dimensional work envelope. A 25 to 30 HP gearbox-driven spindle through No. 50 CAT taper tooling operates at maximum speeds of 3,500 to 4,500 RPM, depending on spindle configuration and production year, prioritizing torque for heavy steel and cast iron milling over high rotational speed. The CNC system on 1994 to 1996 production units is typically a Mitsubishi Meldas 335M-V or Meldas 500, providing reliable G-code execution, canned cycles, and rigid tapping. Overall machine dimensions of approximately 200 by 209 by 149 inches and a weight in the range of 30,000 to 34,000 pounds reflect the structural mass OKK builds into its large-format machines to maintain precision under production cutting loads. The MCV820 is well suited to mold and die shops, heavy job shops, and industrial manufacturers requiring reliable large-format three-axis milling capability.
