Specifications & Market Value

This is a heavy-duty 2-axis CNC horizontal turning center designed for large-scale component machining operations. The machine operates on two linear axes—the X-axis controlling diameter by moving the cutting tool inward and outward, and the Z-axis controlling length by moving the tool along the workpiece. With a turning diameter capacity of 63 inches and a swing over bed of 63 inches, this lathe accommodates exceptionally large workpieces. The 196.85-inch machining length enables extended turning operations for lengthy components up to 3,000mm in length. Powered by a robust 134.1 hp motor, the machine delivers substantial cutting force necessary for precision turning of large, heavy components. The maximum spindle speed of 710 RPM is specifically optimized for this size class, providing adequate torque while maintaining surface finish quality on large-diameter parts. The CNC control system enables precise, repeatable cutting operations and rapid traverse rates that reduce cycle times. The machine incorporates a slant bed construction characteristic of heavy-duty turning centers, enhancing rigidity and thermal stability. This configuration is ideal for manufacturing large-diameter components in high-volume production environments, including heavy industrial applications, aerospace components, and large-scale automotive parts. The combination of substantial spindle power, generous machining envelope, and CNC automation makes this machine suitable for both simple and moderately complex geometries requiring precision and repeatability on oversized workpieces.
