Turned metal has revolutionized the manufacturing industry, offering precision, versatility, and efficiency in producing a wide range of components. This article delves into the fascinating world of turned metal, exploring its processes, applications, and significance in various industries.
Turned metal refers to the process of shaping metal through a turning operation, typically performed on a lathe. This method involves rotating a workpiece while a cutting tool moves along its surface, removing material to create the desired shape and dimensions.
The turning process is fundamental to the creation of turned metal components. It involves several key elements:
1. Workpiece: The raw material, usually a cylindrical piece of metal, that will be shaped.
