OKUMA V920EX CNC LATHES

Technical Description

This CNC vertical machining center features a robust main spindle with a maximum turning diameter of 36.220 inches and a maximum turning length of 33.860 inches, enabling it to handle large and long workpieces efficiently. The spindle accommodates a 24-inch diameter chuck and delivers a maximum speed of 1,250 RPM, powered by a 40 HP motor, providing substantial torque for heavy-duty turning operations. The machine supports a single simultaneous cutting tool, ideal for precise turning tasks. High-speed linear travel along the X, Y, and Z axes, each at 78 inches per minute, allows for swift and accurate tool positioning and complex multi-axis machining capabilities. This three-axis travel capability extends machining versatility beyond conventional 2-axis setups, facilitating milling or off-center operations alongside traditional turning. The combination of large capacity, powerful spindle, and controlled axis movement ensures high efficiency, precision, and repeatability suitable for demanding industrial applications, from large shaft manufacturing to detailed contour turning. The 40 HP spindle motor provides sufficient power for cutting tough materials or performing deep cuts, while the max RPM balances speed and torque requirements. The generous chuck size and axis travels support a wide range of part sizes and geometries, making this vertical machining center versatile for diverse manufacturing needs. Overall, this machine is engineered for high-capacity, precise, and flexible CNC turning, delivering consistent quality in medium to large workpiece production.
