Industrial metal lathes Sinus 330/3000 D Knuth

Industrial metal lathes Sinus 330/3000 D Knuth

Country of origin: Germany, 24 months warranty period

The Sinus 330/3000 D Knuth industrial metal lathe is designed for the machining of large and long workpieces where stability, precision and reliability are required under intensive production conditions. The machine's robust solid cast base effectively dampens vibrations, while the 105 mm spindle opening allows for comfortable machining of long shafts, tubes and larger diameter parts. A mechanical multi-disc clutch ensures smooth spindle start-up even when working with heavy workpieces. The integrated 2-axis high-speed feed, removable bridge section, taper turning device and 3-axis digital position indication allow for more efficient, precise and flexible work in a wide range of metalworking processes.
