YL7120 vertical external lathe is a machine tool used as a cutting tool to machine through holes, flat surfaces, and forming surfaces of workpieces. Grinding can achieve high dimensional accuracy and small surface roughness, with high productivity, suitable for mass production in batches. Most lathes only have the main motion of linear cutting with a lathe blade, without feed motion. In 1898, J.N. Lapyant of the United States manufactured the first mechanically driven horizontal internal lathe. In the 1930s, a double cylinder vertical internal lathe was made in Germany, and a large flat side lathe for processing cylinder blocks was manufactured in the United States. In the early 1950s, continuous bunk beds emerged.
