HANKOOK · PROTURN 90/7000
Specifications & Market Value

This CNC machine features a **swing capacity of 39.3 inches** and a **maximum machining length of 294.41 inches**, enabling it to handle long, slender workpieces with substantial diameter. It is controlled via a computer numerical control (CNC) system, which automates precision machining by interpreting programmed instructions to move cutting tools along multiple axes with high accuracy. The machine frame provides structural rigidity to maintain dimensional stability during operations, while the spindle system rotates the cutting tools at controlled speeds optimized depending on the material and tooling requirements. Typical CNC parameters to ensure efficient and precise cutting include spindle speeds ranging from thousands to tens of thousands of revolutions per minute (RPM), feed rates in thousandths of an inch per tooth, and depth of cut tailored to the workpiece material. This configuration allows for high repeatability and tight tolerances, essential for industries demanding precision such as aerospace and automotive manufacturing. Advanced CNC control enables complex tool paths, automated tool changes, and in-process monitoring, which collectively enhance productivity and surface finish quality. The substantial machining length combined with the swing diameter supports producing long shafts, cylinders, or large structural components with consistent geometric accuracy. Proper workpiece clamping and probe-based inspection during and after machining ensure adherence to specified dimensional and surface finish standards, often to tolerances of ±0.1 mm or better. Overall, this CNC lathe or turning center is designed for high-precision, large-format turning applications, balancing speed, power, and control for reliable manufacturing performance.
