The Swiss slitting machine tool, also known as the Swiss lathe or core lathe, differs from a conventional knife lathe in that it features longitudinal cutting via spindle extension movement rather than tool rest extension movement. Its primary advantage lies in its ability to turn slender shaft parts with diameters below 3mm and length-to-diameter ratios greater than one.
