The Shapes You can make with Metal Spinning

metal spinningIf you have ever wondered how it is possible for aircraft and crucible to have that round shape despite the toughness of steel, you should know that these are products of the process of metal spinning. Through the use of spinning tools like a lathe, metalworkers can create pieces of different shapes. There are many types of metal fit for spin forming, but regardless of the material, there are four shapes you can make in this process.

Hemispheres

The back part of light bulbs is a product of metal spinning. From a flat piece of aluminium, a lathe can easily mould the work piece into something that resembles a bowl. Laboratories often use crucibles, and these are just one type that spin forming can create. Across the fields of architecture and aerospace, there are more complicated items that feature the hemisphere shape.

Cans

No, this does not pertain to the usual aluminium cans from which you drink soda. The cylindrical shape of a can is a little tricky to master, but it is doable. The trick here is to use a special mould that attaches to the lathe, which helps in shaping the metal into the right thickness and shape.

Lids

Perhaps the easiest type of shape to form in this technique is a lid. Most raw work piece materials come in the form of flat discs, which means that all the operator has to do is apply some slight pressure on the edges to create a shallow-depth, dome-like shape. The final touch in making a lid is to roll it over with a few special tools and ensure that the piece does not have rough, sharp edges.

Cones

Missile warheads and airplane beaks are two common examples of a metal cone. Like the shape of a can, perfecting the manufacturing of this can be a little difficult. To create a perfect cone, operators should use a special mould.

For every starting metalworking whiz, it is important to be familiar with the different machines and techniques to use; but beyond that, there is a need to know what a piece of equipment is capable of finishing.
