2000 OKUMA ESV4020 VERTICAL MACHINING CENTER

Technical Description

The 2000 Okuma ESV4020 is a 3-axis vertical machining center manufactured by Okuma Corporation, a Japanese precision machine tool builder. The ESV4020 is the standard designation for Okuma's entry-level 40 by 20 inch VMC platform, closely related to the ES4020 and sharing the same fundamental work envelope, spindle system, and structural configuration. The machine table measures approximately 47 by 20 inches with axis travels of 40 inches in X, 20 inches in Y, and 20 inches in Z, providing a practical three-axis work envelope for medium to large prismatic parts. A 15 HP spindle through CAT40 taper tooling operates across a range from 50 to 8,000 RPM, delivering reliable performance for steel, cast iron, aluminum, and non-ferrous machining. A 20-station automatic tool changer supports multi-operation production programs. The Okuma OSP-U10M CNC control provides conversational and G-code programming, canned cycles, rigid tapping, and Okuma's proprietary thermal error compensation, making the machine accessible and capable across the full range of job shop production requirements. Overall dimensions of approximately 110 by 90 by 117 inches and a machine weight of approximately 8,800 pounds reflect a relatively compact footprint suited to facilities prioritizing floor space efficiency. The ESV4020 offers Okuma's proven engineering quality and control reliability at an entry-level price point, making it a practical choice for shops seeking Japanese precision machining capability with minimized capital investment.
