A thesis presents processing technology of the nozzle by micromilling. The nozzle was divided into two halves, where each required appropriate micromilling tehniques. According to required tolerances of workshop drawings, we have written a technological process of CAM programming, which is suitable for a nozzle made of hardened steel with hardness 60 HRC. We presented a selection of CNC machine, tools and machining parameters. For easier visual representation, we have also added a pictures of the program sequences. At the end we calculated the production costs incurred in processing the nozzle.
