Zanima me zna li ko gdje se mogu nabaviti komponente za cnc gravirnu glodalicu i konstrukciono rješenje.

Znas li ti koliko to kosta ?

Step motor oko 130 Ncm je oko 100 evra ,treba ti tri komada ,navojno vreteno 16/5 je oko 50 evra po metru a kraca su jos i skuplja ,matica sa kuglicama za to vreteno je takodje oko 50 evra ,jedan metar elementarne samo aksijalne vodjice je takodje 50 evra ,na tu vodjicu dolaze i takozvana kolica koja kostaju oko 100 evra po komadu a za jednu osu ti treba cetvoro kolica ...dalje racunaj sam.

Kad sve to kupis treba neko da ti napravi gvozdenu konstrukciju koja onda treba da se pobrusi pre nego sto se na nju montira radna povrsina koja treba da omoguci prihvat tj ucvrscenje materijala koji obradjujes.Preporucujem ITEM-ove ekstrudirane aluminijske profile za radne ploce.Ima i kod nas da se kupi ,6 metara profila sirine 145 mm za oko 150 evra.

Kad i to uradis dolazi na red elektronika ,ajde recimo da si imao srece da si nabavio motore do 2.5 A po fazi pa ces vec nekako sa L297 i L298 da izvuces optimum u samogradnji ili recimo kupis za 100 evra gotov pogon koji se kaci na paralelni port i ne zahteva dodatni PLC kao sto ima recimo na www.maconic.dzaba.com.

Dobro eto sve si to zavrsio ali treba ti i napajanje ,choperski pogon step motora zahteva mnogo vise napona od deklarisanog na motorima a struja ostaje ista ,znaci 3 motora po 2.5 A to je aj da kazemo 8A a napon recimo za L298 za optimalan rad je oko 40-45 V sto opet govori da nece biti lako osim ako ne mislis da motas klasicni trafo ali ni to nije jeftino.

E sad kad si i to savladao treba da savladas i software.Prvo ti treba software za pogon same masine preko paralelnog porta ,ja recimo koristim turbocnc ,to je free,ima na netu,ali treba ti program koji generise NC code,a treba takodje da objasnis svom programu da li tvoja masina interpretira modalno ili non-modalno da li su I i J parametri G02 i G03 komande inkrementalni ili apsolutni a sve to se zadaje u posebnom delu CAM programa koji se zove post procesor.Sve u svemu prvo treba dobro prouciti ISO G-code pa tek onda preci na proucavanje tesko dostupnog kvalitetnog softwarea kao sto je na primer AlphaCam.

I na kraju cemu to sluzi a usput jos i ne radi!

Sve je to uredu u vezi cijene.
A zašto su manja navojna vretena skuplja,mogu sam da napravim gvozdenu konstrukciju samo me zanima oblik,učvršćenja,preziznost izrade...i zna li neko neki 3D laser skener koje firme.

Nedostaje mi jedan od ova dva, zaboravio sam koji, iz kataloga Radio Kluba u Timockoj 18. Da li je neko video negde
(Cene su u radio klubu)

Da dopunim sebe, L298 nedostaje. Dapace, nema ga ni u Mikro-Princ ni ITC. Gde mogu da potrazim jos? Da li ga neko ima na lageru i hoce da ga ustupi(po razumnoj ceni)?

Danas sam ga nasao(L298), Japan Electronic, Pariske komune 59a, i sto je jos lepse, jeftiniji su od Radio Kluba u Timockoj. U ponedeljek dobijam i stampane plocice. Igra moze da pocne.

Interesuje me misljenje "mac"-a posto vidim da je odlicno upucen u CNC tehniku koliko bi u globalu kostala izrada jedne masine za CNC obradu modela za camce, skutere isl poput ove na sajtu nemackog proizvodjaca [url]www.hsm-modal.com[/url].

Ideja je po meni odlicna. Ultralaka konstrukcija od kompozitnih materijala koja i ne zahteva veliku krutost a velika brzina rezanja. Mozda ne mozemo da pravimo petoosne glodalice za precizne pozicije ali ovo bi po meni mogao da bude odlican posao.

Sve preporuke za cnczone.com!
Jedno me interesuje da ne otvaram novu temu.
Gde u zemlji srbiji moze da se kupi zubcasti kajis kao onaj iz stampaca samo da je duzi i da nije polovno(da vijam servise itd..) ?
Gde moze da se kupi navojno vreteno od ~500mm oko 10mm precnik (ne znam tacne oznake za trapezne navoje) i koja je cena? I jel moze da se koristi kao alternativa obican Metricki navoj M10x500mm (ovo mogu lako naci) sa navrtkom napravljenom da ekstra naleze tj da nema zazora? U pitanju je mali hoby cnc projekat

trebaš kuglična navojna vretena , a ne neke trapezne ili dr!

flexmatic beograd ima sve to

ali...cena remena koji tražiš je nešto što bi te moglo pogoditi...


...da ne zaboravim..10mm vreteno je duplo skuplje od 16mm !
ima još toga što ne piše...a može dobro da izbija lovu...

Ne otvarajući posebnu temu napraviću mali upad sa pitanjem: Može li neko da mi pošalje/objavi ovde sve komande iz grupa M, G i T. Na primer: M00-čeka se dejstvo operatera pa sve do npr.M66-ručna izmena alata, pa zatim G00-brzo linearno kretanje pa do G90-apsolutne kote za X,Y,Z. Sve to isto samo za komande iz grupe T.
Imam neke od njih ali nemam sve potpuno, većinu verovatno nikad neću ni koristiti ali neka ima spisak. HVALA, POZDRAV

Note: Other machine functions, like tool change (usually M06) or coolant control, have their M-code value specified by the PLC application not by the CNC software.

Other M-codes (up to M699) can be handled by the PLC application based on the particular machine requirements.

kad se govori o samogradnji u hobi svrhe manja cnc mašina može se kombinovati i od pisaćih mašina iz kojih se mogu izvući klizne staze koje imaju kuglice ili valjčiće pa je trenje gotovo minimalno a ujedno se može i podešavati zazor između vođica. Ujedno tu možemo naći i zupčastu letvu i pogonski zupčanik pa je potrebno samo prilagoditi još poneki zupčanih pa je pogon te ose kompletan.Naravno u toj kobinaciji po y osi pomera se radna površina dok se alat kreće po x osi.
