Abstract

U radu je prikazan proces rekonstrukcije posmičnog prigona 9-osne glodalice, od kojih su tri numerički upravljane. Predmetna glodalica predstavlja veliki potencijal u prototipnoj i maloserijskoj izradi koja se najčešće izvodi u Laboratoriju za alatne strojeve Fakulteta strojarstva i brodogradnje u Zagrebu. Sastoji se od tri translacijske numerički upravljane osi, tri pomoćne translacijske osi te tri rotacijske osi. U radu su opisani moduli alatnog stroja te njihove karakteristike. Nadalje, predložene su izmjene dotrajalih djelova te izrada potrebnih dodatnih pozicija posmične numerički upravljane Z osi. Također, dan je prijedlog za pogonski elektromotor Z osi koji može služiti kao podloga za odabir motora X i Y osi. Ovaj rad predstavlja prvi korak prema potpunoj revitalizaciji i prenamjeni ove 40 godina stare nefunkcionalne glodalice u upotrebljivu CNC glodalicu.

Abstract (english)

The paper presents the retroftting process of a 9-axis milling machine feed drive, three
of which are numerically controlled. The milling machine has a great potential in prototyping
and small series production, which is most often performed in the Laboratory for Machine
Tools of the Faculty of Mechanical Engineering and Naval Architecture in Zagreb. It consists
of three linear numerically controlled axes, three auxiliary linear axes and three rotary axes.
The paper describes machine tool modules and their characteristics. Furthermore, it is proposed
to change the worn out parts and make the necessary additional positions of the numerically
controlled Z axis feed drive. Also, a proposal is given for a Z axis feed drive servo electric
motor that can serve as a template for the selection of X and Y axis motors. This paper
represents the first step towards the complete revitalization and conversion of a 40-year-old
non-functional milling machine into a usable CNC milling machine.
