There are two categories of finishing operations: those that produce minor dimensional corrections, and surface treatment processes. Coining, sizing and straightening are commonly used to improve the dimensional accuracy of forgings. When tolerances closer than those that can be economically produced in the forging die are specified, coining and sizing operations are often employed. These processes cause plastic deformation of the forging, either by striking or squeezing a defined area. Coining may be performed either hot or cold, and can […]
