Metal Spinning and Pressing Processes.
Before we end up with the final metal products, they have undergone several processes of refining and taking form. The metal spinning process involves rotating a metal disc at high speeds, the outcomes will be a symmetrical part. This process can be done by hand or through the use of a device specially made for the purpose.
In spinning of conventional wood there might be removal of some materials but with metal spinning there will be no extraction of any material. Spinning will just be molding a sheet of metal over an existing shape that it’s supposed to take after. Apart from commercial purposes, this process is used by artisans to produce beautiful pieces of metal art. The spinning process is not rocket science in case you thought it was hard, it starts by mounting the formed shape on the driving part of a lathe. The next step involves clamping of the metal disc against the shape through the use of pressure. The rotation effect is then applied to both the metal disc and the block together and at extremely high speeds.
As the spinning continues, pressurized levers with different amount of pressure are applied to the metal disc and it flows over the block with the shape that its intended to take. 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. There is a unique form of spinning were the metal being spun will be exposed to a hot torch as it continues to rotate . Compared to normal spinning, hot spinning goes a little faster due to the fact that heat makes metals easy to fold under pressure . In some cases this process will see heating that is followed by rapid cooling and this makes it a very effective.
Spinning of metal has some unique advantages that you wouldn’t find when using other metal forming methods. Metal spinning allows you to make alterations to the geometry but the benefit is that it will cost you less. 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 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.
