Before we end up with the final metal products, they have undergone several processes of refining and taking form. The metal spinning process features the rotation of a metal disc or a tube at very high speeds and we end up having a symmetrical part. This process can be done by hand or through the use of a device specially made for the purpose.
Some spinning processes such as in conventional wood, you will discover that there will be removal of some materials in the process but with metal spinning there is no such thing. This process will just form sheet of metal over an existing shape. Apart from commercial purposes, this process is used by artisans to produce beautiful pieces of metal art. 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 rotation effect is then applied to both the metal disc and the block together and at extremely 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. Ice is also popular with multi piece blocks because it melts after he work is done leaving the metal disc with the shape. The spinning process can also include the high temperatures from a hot torch, this process is known as hot spinning. Hot spinning is faster in comparison to the normal way of spinning with no application of heat, hot metal is easy to fold. Artisans will usually heat and rapidly cool the metal as that way you can achieve results that you are after.
Using metal forming techniques has some benefits that you wouldn’t find in other metal forming methods. This can be seen in the ease of making alterations and usually at very low costs. Metal pressing also referred to as stamping is placing metal sheets in a machine so they can be made into a net shape. Metal pressing does not involve one activity , there are options that can be used to turn that metal into the desired shape. 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 in metal pressing reduces the thickness of the metal by pressing it against a surface.
