A metal spinner fabricates symmetrical metal parts with the use of specialized equipment. Traditionally, this requires working metal by hand, but modern equipment may allow workers to use a computer numerical control (CNC) lathe. Metal spinners determine the most appropriate materials and construction method for projects ranging from custom-shaped cones for use in rocket construction to mass-produced metal light fixtures. This work requires familiarity with industrial environments and comfort with a range of metalworking equipment.
In traditional metal spinning, a worker takes a block form and clamps a piece of sheet metal over it. The next step involves rotation while applying pressure to encourage the metal to deform and flow over the block, taking on the shape of the form. The metal spinner can finish the process with polishing to smooth the surface, eliminate any burr along the edges, and even out the texture. These projects vary widely in the time required to complete them, depending on complexity and supplies needed.
The metal spinner needs to be able to determine which metal to use for the project and may need to design a form if a facility does not have a suitable shape. The process can also involve making test pieces to show the client, demonstrating the range of options available. For complex, custom projects, several client meetings may be necessary to go over specifications and other issues. This assures a high quality finished product for the customer.
Facilities can also utilize CNC metal spinning for their products. In this case, the metal spinner does not actually work the metal, but does need to be able to program the equipment to perform the desired task. The work also requires an understanding of the properties of various metals to select the most appropriate for the client. The fabrication of test components is also necessary to check the tolerance level of the equipment which may help to address any concerns the client may have about the project before production begins.
To become a metal spinner, people may train on the job under the supervision of experienced technicians. They can also attend a technical school to learn metalworking techniques, study the properties of metals, and get training on the type of equipment they may use. The work can require subscriptions to trade publications and other continuing education opportunities to keep up with developments in metalworking, like the invention of new alloys and production methods. This ensures that clients get access to the latest techniques and technology.
