OKUMA MC-3VA CNC VMC VERTICAL MACHINING CENTER

Technical Description

The OKUMA MC-3VA is a compact vertical machining center engineered for precision production work. This machine features a 13" x 30" work table with a 660-lbs load capacity and delivers impressive rapid traverse rates of 797 IPM on the X and Y axes and 594 IPM on the Z axis, enabling efficient part-to-part transitions. The spindle operates across a 30-6,000 RPM range with a CT 40 taper, accommodating a 16-tool automatic tool changer for streamlined tool selection and changeovers. Equipped with a 10 HP spindle drive motor rated for continuous duty, the machine provides robust cutting performance across diverse applications. Travel specifications include 20" on the X-axis, 12" on the Y-axis, and 15.75" on the Z-axis, supporting mid-range workpiece dimensions. The machine is controlled by an OSP-500MG CNC control system, featuring a 9" monochrome CRT graphic display and conversational programming capabilities that facilitate ease of operation. Standard accessories include table chip guards, a remote manual pulse generator, and a multi-tap transformer. This configuration makes the MC-3VA suitable for general machining, including milling, drilling, and boring operations. The inclusion of all available manuals and a coolant tank ensures immediate operational capability. Originally manufactured in the late 1980s, this machine remains a reliable workhorse for job shops and manufacturing facilities requiring dependable precision machining in a space-efficient footprint.
