In hardware processing, lathe processing is a relatively common processing mode. Although metal spinning can be carried out by hand, the use of metal spinning machinery such as lathe to achieve the effect of metal spinning is a very common method in industrial and personal machine workshops.
Metal spinning uses a rotating metal disk to shape a work piece by “flowing” metal into a predetermined shape. The process is often used to make round metal parts and products ranging from aerospace parts to decorative household items.
Its reliance on rotary metal forming makes metal spinning somewhat similar in principle to lathe metalworking. Unlike lathe processing, however, metal spinning relies on a mandrel that complements the internal curvature of the workpiece, rather than the clamping device needed to hold the metal blank in place. Despite these differences, many lathes can be installed to perform metal spinning operations.
It is important to note that the lathe manufacturer should be consulted before changing machine Settings, and a trained professional is required to operate the lathe and metal spinning skills to ensure safe and efficient production.
Metal spinning operation
In its basic process, metal spinning is centered on a metal workpiece or blank, sandwiched between a rotating manspindle and a spindle tool. As the mechanism rotates these parts, the rotary roller is pressed against the workpiece using manual or automatic control.
The workpiece is then positioned on the mandatore, which shapes the metal into the desired design through a series of axial trips transmitted by rotation. This process may change the material thickness of the workpiece, and due to its unique method, the metal may “flow” into shape as if it were malleable and soft.
Metal spinning usually results in parts that are symmetrical and have a circular cross section, although these parts are often cut and reassembled into new products. The final assembly is usually smaller than the diameter of the blank piece, but has a similar surface area.
While it was once limited to softer metals and short-term production runs such as prototyping, current metal spinning methods can produce highly durable materials in large quantities. Likewise, size restrictions have become less of a concern.
The metal spinning process can now produce parts dozens of feet long and up to three inches thick, depending on the metal.
