Prednosti: Submikronska natančnost: Dosežite submikronsko (< 1 µm) natančnost brušenja zahvaljujoč švicarskemu inženiringu in robustni zasnovi stroja. Zanesljivo in trajnostno delovanje: Zagotovite visoko zanesljivost ter stabilen in stalen proces. Stroškovna učinkovitost in visoka produktivnost: Nižji proizvodni stroški in visoka produktivnost zaradi krajšega časa brušenja in skrajšanih časov na naslednjih postopkih (valjasto brušenje). Quirlig brusna tehnika: Optimiziran proces brušenja z Quirlig tehniko – pravilno izdelane središčne luknje s križno brušeno površino. Križna struktura brušene površine zagotavlja zadrževanje olja, ko je obdelovanec vpet med konicama, kar ustvarja mikro oljni sloj. Ta preprečuje nezaželeno "suho delo" med valjastim brušenjem. Nizki stroški vzdrževanja: Ugodnejše vzdrževanje stroja skozi življenjsko dobo, zahvaljujoč švicarski kakovosti. Stroji za brušenje središčnih lukenj serije Zentroflex M so zasnovani za visokoprecizno valjasto brušenje v letalski, avtomobilski in strojni industriji. Povrh tega je serija Zentroflex M idealna rešitev za obnovo delov, ki so se deformirali po toplotni obdelavi, ali za zmanjšanje stroškov valjastega brušenja. Za več informacij nas kontaktirajte.
