Metal Spinning and Pressing Processes.

The process of making polished metal products is a detailed one that sees the metal undergo several processes. The process of metal spinning is a process through which a discs or tubes of metal are rotated at high speeds and we end up having a different symmetrical makes. Rotating can be done by hand or through the use of a device known as a CNC lathe.

In spinning of conventional wood there might be removal of some materials but with metal spinning there will be no extraction of any material. This process will just form sheet of metal over an existing shape. You will find artists using this process to make creative pieces and when going large scales there are plants that produce metal discs for commercial purposes through this way. The spinning professional starts by mounting an already formed shape on the driving part of the lathe, this shape is one from which the metal sheet will take shape from. The next step involves clamping of the metal disc against the shape through the use of pressure. The next step will involve rotating the metal disc and the block together and extremely fast as well.

As the two are spinning , different levers with varying amount of pressure are brought in where they force the metal disc to flow over the block gradually to a point that its completely covered. In an event where the piece of metal to be made is a multi-piece, a multi piece block will be used. Ice can also be used in making the blocks for spinning because after the work is done it, melts away. The spinning process can also include the high temperatures from a hot torch, this process is known as hot spinning. Compared to normal spinning, hot spinning goes a little faster due to the fact that heat makes metals easy to fold under pressure . In metal works after metal has been worked on when hot it’s cooled rapidly so as to have the results just the way the artists wants.

Spinning of metal has some unique advantages that you wouldn’t find when using other metal forming methods. This can be seen in the ease of making alterations and usually at very low costs. Metal pressing on the other hand involves placing metal sheets in a machine that will make them into a net shape. Metal pressing involves a lot of processes that can be explored so as to turn the metal into the desired shape. Bending is among the most common metal pressing procedures, here the metal is bent and usually along a line. Ironing is another metal pressing technique, the metal here is forced against a surface and the desired result will be reducing the thickness of the metal.
