An overview of inductive gear spin hardening

Gap-by-gap, tooth-by-tooth and gear spin hardening are three different methods used for gear hardening by induction. While it is only possible to harden parts of the gear step by step using the first two methods, gear spin hardening allows all the parts of the gear tooth perimeter to be hardened simultaneously. One of the biggest advantages of gear spin hardening is its easy integration into the process flow, and it is for this reason that it has become increasingly significant in large-batch production over recent years. The aim of the article is to present the process-related possibilities and special features of this hardening procedure.
