Four-stroke Internal Cobustion Engine Head Machine

U ovom radu osnovna tematika je obrada glave motora i postupci koji služe u te svrhe. Obrađuju se osnovna anatomija četverotaktnih motora kao tehnike obrade kojima se osiguravaju nominalne dimenzije i točnosti koje su potrebne za ispravan rad motora. Opisuju se razlike između procesa brušenja, honanja i tokarenja kao i njihove osnovne karakteristike i tolerancije koje se mogu dobiti u svakom pojedinom postupku. Nadalje analizira se primjer reparacije glave motora i tehnike koje se koriste u svakodnevnom radu.The main topic of this paper is machining engine heads as well as the processes that makeup engine head reparation. Basic four-stroke engine anatomy is explained as well as the techniques for machining with which we can achieve nominal dimensions and precisions that are needed for the correct functioning of the engine. The difference between grinding, honing and turning is explained as well as their principal characteristics and precisions which can be achieved with each of those individual processes. After that, an example of engine head reparation is shown with the techniques that are used in everyday work
