Increase of Firmness of the Metall-Cutting Tool on the Basis of Removal of Internal Tension in Replaceable Cutting Insert

Results of research of types of the destruction caused by existence of internal tension in a tool firm alloy at production of the replaceable many-sided plates (RMSP) which can be removed by preliminary heating of cutting plates prior to cutting process are given in work. The new technical solution on realization of a method of preliminary heating of SMP is developed for removal of internal tension in the tool firm alloys (TFA), and also the special design of the metal-cutting tool is developed for increase of operability of hard-alloy SMP with preliminary heating.
