Výhody: Submikrometrová presnosť: Dosiahnite submikrometrovú (< 1 µm) presnosť s podporou švajčiarskeho inžinierstva a robustnej konštrukcie. Udržateľná spoľahlivosť: Zabezpečte spoľahlivé a dlhodobé obrábanie. Nákladová efektívnosť a vysoká produktivita: Profitujte z nízkych výrobných nákladov a vysokej produktivity vďaka rýchlemu brúsnemu procesu a skráteniu času následného cylindrického brúsenia. Quirlig brúsna technika: Využite optimalizovaný brúsny proces s Quirlig brúsnou technikou. Správne obrobené stredové otvory s krížovým brúsnym vzorom. Tento vzor zadržiava olej pri upnutí medzi hrotmi počas cylindrického brúsenia, čím sa vytvára mikro olejový film. Ten zabraňuje nechcenému "suchému chodu". Jednoduché použitie CNC panelu: Veľmi jednoduchá obsluha a programovanie vďaka Beckhoff panelu a servopohonu osi Z. Gjdpfx Aaogb Ec Hometw Industry 4.0: Plná kompatibilita s aplikáciami Industry 4.0 vďaka Beckhoff riadeniu. Nízke prevádzkové náklady: Vďaka švajčiarskej kvalite konštrukcie sú náklady na údržbu po celý životný cyklus stroja minimálne. Brúska stredových otvorov série Zentroflex SA je určená na vysoko presné cylindrické brúsenie v oblastiach letectva, automobilového priemyslu a strojárstva. Zentroflex SA je ideálnym riešením aj na opravy dielov deformovaných po tepelnej úprave alebo na zníženie nákladov na cylindrické brúsenie. Pohyb v osi Z je riadený servomotorom v CNC prevedení. Založenie, vybratie a upnutie obrobku prebieha manuálne. Nastavenia sa vykonávajú cez CNC ovládací panel, brúsenie sa spúšťa stlačením štartu. Počas brúsenia už nie je potrebné žiadne ručné nastavenie či zásah. Kontaktujte nás pre viac informácií.
