The Process Of Turning Steel

Turning Steel

Turning is a machining process used to make a cylindrical surface by passing a hardened cutting tool past a supported, rotating part. Very accurate parts of a variety of shapes and sizes can be produced. The machine used to turn a cylindrical shaped surface is called the lathe. Typical turned objects related to mold base technology are leader pins and bushings, ejector and core pins, inserts, sprue bushings, and angle pins. Shown here is a computer numerical control (CNC) production lathe used to turn cylindrical shapes.
