Kako odabrati pravu mlaznicu za svoju primjenu
Odabir prave mlaznice može biti ključ savršenog rezultata lasera. Osim toga, mlaznica je glavna zaštita od prašine za leću. Ovdje pročitajte koja mlaznica odgovara vašoj aplikaciji.
Izbor mlaznica
Postoje 3 različite mlaznice koje možete odabrati:
Kratka mlaznica velikog promjera otvora (7 mm)
Kratka mlaznica velikog promjera otvora (7 mm), standardna mlaznica , može se koristiti i za lasersko graviranje i za lasersko rezanje.
Kod rezanja ova se mlaznica prvenstveno koristi za <vezu 96 > lasersku obradu akrila jer se materijal ne hladi tako brzo, a to stvara prekrasan rub od sjajnog plamena.

Kratka mlaznica s malim promjerom rupa (3 mm)
Kratka mlaznica s malim promjerom rupe (3 mm) uglavnom se koristi kod reznog materijala koji stvara višak dima   poput drveta . Zbog malog otvora, koncentrirani protok zraka usmjerava se u kerf, ispuhavajući nastajući dim i plinove za rezanje.
Ova mlaznica je manje pogodna za graviranje materijala koji staraju puno prašine, poput plastike ili gumenih pečata. Prašina graviranja talože se brže na otvaranju mlaznice i može je blokirati, uzrokujući rupu za izgaranje u leći.

Duga mlaznica s malim promjerom rupe (3 mm)
Posebno za uporabu u kombinaciji s 2,5 "lećom , još uvijek postoji duga mlaznica s malim promjerom rupa (3 mm). To kompenzira veću žarišnu udaljenost između 2,5" objektiva i materijala. Svojstva mlaznice jednaka su onima njegove kratke strane.

Bakrene mlaznice za lasersko rezanje komprimiranim zrakom
Za lasersko rezanje komprimiranim zrakom na SP500 postoje dodatne bakrene mlaznice s promjerom rupa 1,7 mm za kratke mlaznice. Zbog izuzetno malog promjera, strujanje zraka se usmjerava u kerf još ciljanije. Na taj način postižete savršen laserski rez na materijalima poput debljeg drva od cca. 5 mm ili polikarbonat.
Ovisno o korištenom objektivu i rezultiranoj žarišnoj udaljenosti, postoje pričvršćenja u četiri različite duljine.
