Micro-forging
0607101-110
[DEFINITION]
A micromachining process for performing microscopic forming using
tools or dies to compress or impact a material.
[DESCRIPTION]
There is strong demand for high precision in forging, and this is
developing toward reducing after-processing stages to the minimum and toward so-called
near-net-shape forming. Most microcomponents are not completed by forging only, but forging is used
in some processing stages. An example is the production of the steel balls for bearings. Cut round
rods are initially forged to a spherical shape by a compression forming (plastic working) stage.
Subsequently, the balls are completed by grinding, heat treatment, and lapping.
