HANKOOK PROTEC-9E/4000 MANUAL LATHE

Technical Description

The HANKOOK PROTEC-9E/4000 is a heavy-duty manual lathe designed for high-precision turning of large workpieces. With a maximum swing of 37.3 inches and a distance between centers of 157.6 inches, this lathe is well-suited for machining long shafts and substantial components. The machine features a robust, one-piece cast iron bed with induction-hardened and precision-ground guide ways, ensuring exceptional rigidity, stability, and resistance to deformation during heavy cutting operations. The spindle bore measures 3.3 inches, allowing for the passage of large-diameter bars or workpieces. Powered by a 20.0 HP motor, the lathe delivers strong torque and consistent performance, supporting a maximum spindle speed of 1,120 RPM for efficient material removal and fine surface finishes. The headstock is engineered for durability, with precision spindle bearings and forced lubrication to minimize thermal growth and maximize spindle life. The lathe’s design incorporates a wide cross slide and extended saddle for enhanced stability during interrupted cuts and heavy-duty machining. Manual operation is facilitated by ergonomic handwheels and precise controls, making it accessible for both experienced and novice operators. The PROTEC-9E/4000 is ideal for applications requiring high load capacity—up to 5,000 kg between centers—and reliable performance in demanding industrial environments. Its sturdy construction, combined with attention to detail in component selection and assembly, ensures long-term accuracy and productivity for a wide range of turning tasks.
