How to make tool for hot work tool steel?
Tool made of hot work tool steel are manufactured by metal cutting and non cutting shaping processes. During metal cutting, surface tensions are generated and the tension of the work piece is changed, depending on the depth of machining. In the event of extensive metal cutting, it is recommendable to perform thermal relief for annealed and quenched and tempered parts before finish machining, in order to reduce the risk of distortion or stress cracking during finish machining. Critical machining process are processes in which the structure of steel is changed by thermal influences.
