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. This process can be done by hand or through the use of a device specially made for the purpose.
In the process of metal spinning there will be no removal of materials as you would find with other processes such as conventional wood. This process will just form sheet of metal over an existing shape. The process is applied in artistic work by professionals skilled in producing art work of this kind. 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 metal sheet will then be clamped against the block through pressure clamps. The metal discs together with the block are then rotated together at very high speeds.
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. Surprisingly hard ice can be used in the process of making the metal adopt the shape because it conveniently melts after the process is complete. There is a unique form of spinning were the metal being spun will be exposed to a hot torch as it continues to rotate . The heating process makes the spinning go a little faster because it is easier to alter metal when it is hot. 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. There are a variety of metal processes that could be used in metal pressing. Among the most common metal stamping processes bending tops the list, to bend the metal sheet will need you to use a straight 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.
