ВИСОКОПРОДУКТИВНІ АБРАЗИВНІ ІНСТРУМЕНТИ БАРАБАННОГО ТИПУ ОСНАЩЕНІ ЗМІННИМИ РІЖУЧИМИ ЕЛЕМЕНТАМИ З НТМ

The processes of synthesis of the working layer of abrasive tools using various methods are considered, their features and disadvantages are noted. The results of the use of laser radiation for sintering composites with SHM are presented. It is shown for the first time that laser heating of composites containing a metal bond and SHM grains to temperatures of 1600 ºС does not lead to a loss of their strength. It is shown that the time of action of laser radiation and melting of the bond on SHM grains should not exceed 0.3 sec. Data on high-performance drum-type tools equipped with replaceable inserts with SHM are highlighted. The results of mathematical modeling of the processes of forming a layer with SHM, methods for calculating sintering parameters are highlighted, a set of devices and means for ensuring the process of manufacturing abrasive diamond inserts for drums is presented.
