DEVICE FOR MAKING HOLES IN SUPERHARD HARD-TO-MACHINE AND BRITTLE MATERIALS

摘要

A device for making holes in superhard hard-to-machine and brittle materials comprising a mixing chamber has an additional nozzle and a means for supplying the abrasive material, another nozzle arranged below for supply of cryogenic fluid. The nozzle for supplying abrasive grains has a throttling element that provides a certain ratio of consumption of abrasive grains and cryogenic fluid.
