Návrh technologického postupu výroby součásti pro automobilový průmysl

Abstract

This thesis deals with the technological process of components called Key 119 59, where the material is free-cutting steel 11 109. The work was carried out in the company Josef Keprt and solves the rationalization of production on HEADSTOCK CNC machine. The paper describes the machine itself KMX 626, we discuss its technological advantages, clamping tools and standard equipment of the machine. In the following section are described measurements and properties of the desired components and final surface adjustment called hot galvanizing. In the last part new technological process is drawned up. New cutting conditions lead to savings in machining time and thus saving labor costs. In the final conclusion new technological process is compared with old one, machinery times and compared to previous ones
