Turning is a common method of manufacturing, where a rotating workpiece is fixed on a machine tool, and a cutting or grinding tool is used to create the desired shape and size on the surface. In the production of heat sinks, machining is often used to process smaller parts with higher precision, such as connecting brackets for fan bearings and fan frame.
Turning requires the use of a lathe machine and corresponding tools. The lathe machine can cut and grind the desired shape on the workpiece surface according to the required dimensions and shape, while the shape and material of the cutting tool can affect the efficiency and processing quality of machining.
