Porovnání řezivosti vrtáků z různých nástrojových materiálů

Abstract

My thesis is oriented on the drill cutting efficiency comparsion of the drills made of the different tool materials. Compared materials are high-speed steel made using classical method and high-speed steel made using powdery metalurgy. In the Introduction part, materials will be described by machanical properties, production and posibilities of using. We will also mention used coating. Theoretical part is oriented on endurance tests of drills made of these materials. In the conclusion part, the comparison of the results achieved during experiments is done.
