OKUMA CROWN 762SBB CNC LATHE

Technical Description

This CNC lathe features a 10-inch chuck and a bar capacity of 3.15 inches, designed for efficient turning of medium-sized workpieces. It operates on 2 axes (X and Z), with travel distances of 7.28 inches on the X-axis and 20.47 inches on the Z-axis, supporting precise manipulation of tool position. The machine delivers 22 kW of power, driving a spindle that achieves speeds up to 3,500 RPM with variable spindle speeds ranging from 65 to 3,500 RPM. Its maximum turning diameter is 10.63 inches, supported by 21.65 inches swing over the bed and 15.75 inches swing over the cross-slide, enabling machining of workpieces with considerable radial dimensions. The spindle bore diameter stands at 3.15 inches, with an outer spindle diameter of 4.72 inches, facilitating the accommodation of sizable stock materials. The tailstock features a quill diameter of 3.54 inches with a Morse Taper #5 and a stroke length of 4.72 inches, allowing additional support for long or slender parts during machining. Rapid traverse rates of 590 IPM on the X-axis and 787 IPM on the Z-axis ensure quick positioning between cuts, promoting high productivity. The lathe’s distance between centers is 22.29 inches, suitable for mid-length parts. Electrical requirements specify a 220 V three-phase power supply. This setup is ideal for precision turning tasks requiring consistent accuracy and repeatability, suitable for components needing moderate swing and power capabilities in automotive, aerospace, or general manufacturing environments.
