Metal spinning is a traditional manufacturing process used to obtain spun parts by deforming a rotating disc of sheet metal.
This pre-cut disc-shaped blank rotates at high speed on the lathe and, by means of a tool consisting in a roller wheel attached to a lever, is pressed against a steel-made mold, also called mandrel, which shapes the part to be obtained.
The whole process can be hand-crafted or CNC controlled with state-of-the-art CNC spinning lathes for large quantity productions with minimum tolerances.
Metal spinning is suitable for a wide range of metals such as mild steel, aluminium, stainless steel, zintec, copper and brass, with thickness up to 3 mm according to the material.
Spun products are characterized by a symmetric hollow shape, like cylinders, cones, hemispheres and rounded parts in general. Finally, spinnings can be easily recognized by an exceptional finishing which gives brightness and shininess to the part.
