A metal lathe is a machine tool used for shaping metal or other materials. It works by rotating the workpiece against a cutting tool, allowing for precise shaping, drilling, and finishing. Metal lathes are commonly used in manufacturing and metalworking industries to create parts for machinery, automotive components, and various other applications. These machines come in various sizes and types, including CNC lathes for automated processes and manual lathes for hands-on operation. Operators can adjust the speed and feed rate to achieve desired results, making metal lathes versatile tools for both professionals and hobbyists in the field of machining.
