Advantages 5. Limitations 6. Applications and Uses 7. Lubrication. Meaning of Spinning: Spinning is a sheet metal forming process in which a metal blank is pressed over a rotating chuck or form mandrel with the help pressing tool to obtain axisymmetric hollow shell. The sheet metal parts that have circular cross-section can be made by this process. This limit is determined by the properties of the material and the conditions of the forming process, such as the type of tooling, sheet metal gauge, and lubrication used during the forming process. Two common tests which can be conducted to test the forming limit of sheet metal is the cupping test (the Erichsen test) and the Bulge test.
Metal forming is a complex process that requires a high level of skill and expertise. The success of the process depends on many factors such as the type of material being formed, the equipment being used, and the experience of the operator.
