Abstract

Ovaj završni rad bavi se tematikom sklopova obradnih strojeva i mogućnostima poboljšanja njihovih karakteristika. U uvodnom dijelu ukratko je opisana povijest i razvoj obradnih strojeva. U nastavku je dana podjela i opis obradnih strojeva prema tehnološkom prostoru. Osim toga, detaljno su objašnjeni glavni moduli obradnih strojeva odnosno pogonski sustavi, postolja, vodilice, sustav za prihvat alata i naprave za stezanje obradaka. Povrh svega, prikazane su i detaljno opisane razne inovacije sklopova obradnih strojeva u svrhu poboljšanja značajki i mogućnosti tih strojeva. Za poboljšanja pogonskih sustava opisano je pametno motorvreteno te hibridni ležajevi za uležištenje, implementacija momentnog motora u okretno nagibni stol i revolversku glavu te direktni posmični pogon. Također je prikazan sustav hlađenja kugličnog navojnog vretena i matice, a za poboljšanje karakteristika postolja obradnog stroja objašnjena je primjena mineralnog lijeva.

Abstract (english)

This bachelor thesis deals with machine tool modules and possibilities of improving their characteristics. In the introduction, history and development of machine tools is described. In further part division and description of machine tools according to technological space is given. Additionally, machine tool modules are explained with great detail including motor systems, machine tool base, guideways, system for tool clamping and devices for workpiece clamping. Furthermore, different inovations of machine tools modules are showed and described with great detail all in purpose of improving characteristics and possibilities of machine tools. For improvements of motor systems smart motorspindle and hybrid bearings are described together with implementation of torque motors in rotary tilting table and turret head, as well as direct linear drive. There is also presented system of ball screw and nut cooling, and for improvement of characteristics of machine tool base implementation of mineral cast is described.
