Cold finishing is a metalworking technique that involves changing the shape of metal without heat, resulting in a stronger finished product. This process can be used on various metals, including steel, and can be done by hand or with equipment that applies pressure. The end result is a smooth surface and components that resist wear, making them ideal for use in machinery and construction projects.
A cold finish, or cold finish, is a strategy used to alter the shape and improve the strength of different types of metal. Commonly used with steel and similar metals, this approach involves using an approach other than heating the metal to change the shape of the metal into rods or other shapes while also hardening the finished metal product. In fact, the process is sometimes referred to as cold quenching in reference to the result of using this particular method in metalworking.
While the name “cold finish” conjures up images of using extreme cold to manage the process, this approach is more about the absence of heat than the application of cold. A simple example of handling a cold finish on a metal has to do with changing the shape of a section of copper pipe. Using simple tools like a hammer to flatten the pipe will eventually result in a new shape that is much less flexible and has a higher degree of strength than the original rounded section. This flatter, stronger section can then be used in applications that would not have been possible before.
This same process of using pressure to flatten and then strengthen metals for use in specific applications can be employed with a number of metals. For example, steel can be reshaped in this way, gradually adding strength to the reshaped sections and making the finished product ideal for specific uses. Cold finished steel bar can easily be used in construction projects to add a degree of stability to construction that would be difficult to achieve using other materials. As part of the forming process, cold finishing also allows the shape of objects to be molded and refined to any required size. The end result can also include a smooth surface which is achieved with the use of constant pressure exerted on the surface of the metal while performing this method of metal shaping.
The use of a cold finishing technique allows a wide range of components to be formed that can be used in machinery and construction projects. Gears and other machine parts can be formed using this approach, creating components that resist a great deal of wear. While it is possible to cold finish a metal by hand in some cases, using equipment that can deliver immense pressure to the metals is a more common approach today.
