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.
