HEYLIGENSTAEDT HEYNUMAT 21U/6000 CNC LATHE

This CNC lathe is engineered for high-precision, heavy-duty turning operations, featuring a distance between centers of 239 inches, allowing for the machining of exceptionally long workpieces. The maximum swing over the bed is 21.65 inches, while the maximum cutting/turning diameter reaches 25.98 inches, accommodating large-diameter parts. Rapid traverse is rated at 468 inches per minute, ensuring efficient tool movement and reduced cycle times. The machine is equipped with an 18.0-inch hydraulic 3-jaw chuck, providing secure and consistent workholding for a variety of part geometries. The spindle bore measures 5.50 inches, supporting the passage of bar stock or long workpieces, and the spindle speed is capable of up to 1,800 RPM, driven by a robust 75 HP spindle motor for demanding cutting applications. The tool turret offers 12 positions, enabling versatile tooling setups and minimizing changeover time. Control is managed via a Siemens Sinumerik 840D CNC system, delivering advanced programming, diagnostics, and operational flexibility. The lathe also features a programmable tailstock, enhancing setup automation and part support for extended machining runs. This configuration is ideal for high-volume production and complex turning tasks requiring accuracy, repeatability, and adaptability.
