HEYLIGENSTAEDT HEYNUMAT 21U CNC CNC LATHE

This is a heavy-duty CNC turning center engineered for high-capacity production of large cylindrical components. The machine features a 15.75-inch chuck and 3-inch bar capacity, accommodating substantial workpieces with a maximum turning diameter of 28.3 inches and swing clearance of 28.3 inches. The extended machining length of 157 inches enables production of lengthy shafts, tubes, and similar parts requiring significant axial access. Operating on two axes (X and Z), this machine provides precise cross-slide and longitudinal feed control essential for accurate turning, boring, and facing operations. The 75 hp main spindle motor delivers robust cutting power, operating at a maximum speed of 2,240 RPM, optimizing performance for heavy-duty roughing and finishing applications on ferrous and non-ferrous materials. The integrated automatic tailstock provides steady rest support for extended workpieces, enhancing surface finish quality and dimensional accuracy while reducing deflection during machining. Full CNC control ensures repeatability, programmability, and consistent precision across production runs. The rigid machine construction, typical of industrial-grade turning centers, minimizes vibration and maintains tolerances during sustained cutting cycles. This configuration is ideal for job shops and production facilities specializing in large component machining, including industrial shafts, rolls, and similar turned parts requiring dependable, high-capacity machining capabilities with extended workpiece support.
