Case-hardening - Wikipedia

2019-11-9  Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface. For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening

Deburring and electro-chemical Deburring

Deburring does not count as a core process in machining. On the contrary, it has up to now been considered a necessary evil. Again and again this has led to the machining processes being optimally coordinated, whilst the cost-effectiveness of the system as a whole suffered, owing to the fact that deburring was not taken into consideration as being part of the process chain right from the word go.
