Abstract

U ovome radu predstavljena je stolna 3-osna CNC glodalica kućne izrade ručnim alatima. Radni volumen ove CNC glodalice iznosi 90 x 90 x 155 mm, ona je zavarene čelične konstrukcije od izrezaka s otpada. Većina dijelova i materijala ugrađenih u ovu CNC glodalicu reciklaža je s otpada. Vodilice X, Y i Z osi izvedene su cementiranim šipkama okruglog poprečnog presjeka promjera 12 mm s brončanim kliznim ležajevima. Posmični prigoni pogonjeni su NEMA 17 koračnim motorima preko metričkih navojnih šipki M6 od nehrđajućeg čelika kao navojna vretena i brončanim maticama. Glavno vreteno pogonjeno je preko remenskog prijenosa motorom od brisača automobila. Glavno vreteno jest iz Proxxon bušilice/brusilice, dok je vretenište vlastite izrade. Sve komponente napajanja, (transformator, diode, kondenzatori), većina kablova, sklopke, tipkala i tako dalje jesu reciklaža. Upravljanje je izvedeno s pomoću Arduino CNC mikroupravljača.

Abstract (english)

This paper presents a homemade desktop 3-axis CNC milling machine. The working volume of this CNC milling machine is 90x90x155 mm, and it is constructed from welded steel scraps. Most of the parts and materials used in this CNC milling machine are recycled from scrap. The X, Y, and Z axis guides are made from hardened round steel rods with bronze sliding bearings. The linear drives are powered by NEMA 17 stepper motors via M6 stainless steel threaded rods as lead screws and bronze nuts. The main spindle is driven by a belt transmission powered by a car wiper motor. The main spindle is from a Proxxon drill/grinder, while the spindle mount is homemade. All power components (transformer, diodes, capacitors), most cables, switches, buttons, etc., are recycled. Control is achieved using an arduino CNC microcontroller.
