Meaning of SPINNING in English

SPINNING

n.

In metalwork , a technique for making hollow metal utensils and artifacts.

Developed in the 19th century, the method can be used for most metals. A metal disk is set on a lathe behind an appropriately shaped metal or wooden chuck; while the lathe is rotating, the metal is pressed onto the chuck with a tool. A typical modern spun object is the aluminum saucepan. As in most metalworking techniques, the metal is periodically softened by annealing , or heating, when it has become hardened by being worked (see hardening ).
