Pohyb brúsneho kužeľa: 3+1 osi - Rotácia - Orbitálna rotácia - Pracovný zdvih +1 Rotácia obrobku Quirlig brúsna technika: Súčasťou dodávky (krížové brúsenie) Brúsiaci proces: Polautomatický, CNC Ovládací panel: Beckhoff CNC pohyby: Z-os Kompatibilita s Industry 4.0: Áno Polautomatické tvarovanie brúsneho kužeľa: Súčasťou dodávky Rotácia obrobku: K dispozícii (voliteľné) Odsávanie a filtrácia prachu: K dispozícii (voliteľné) Sektory: Presné brúsenie, letectvo, automobilový priemysel, strojárstvo atď. Bsdpfx Aogb Ec Hefwolr Výhody: Submikrometrová presnosť: Dosiahnite submikrometrovú (< 1 µm) presnosť vďaka švajčiarskemu inžinierstvu a robustnej konštrukcii stroja. Dlhodobá spoľahlivosť: Zabezpečte spoľahlivé a udržateľné spracovanie. Nákladová efektivita a vysoká produktivita: Využívajte nižšie výrobné náklady a vysokú produktivitu vďaka krátkemu brúsnemu procesu a zníženým časom následných procesov (valcové brúsenie). Quirlig brúsna technika: Využívajte optimalizovaný proces brúsenia so systémom Quirlig. Správne brúsené stredové otvory majú krížový vzor, ktorý zabezpečuje zadržiavanie oleja pri upnutí medzi hrotmi počas valcového brúsenia, čím sa vytvára mikrovrstva oleja a zabraňuje "suchému chodu" pri brúsení. Jednoduché CNC ovládanie: Využívajte veľmi jednoduché ovládanie a zapisovanie brúsnych programov prostredníctvom Beckhoff ovládacieho panela a servopohonu v osi Z. Industry 4.0: Plná kompatibilita s aplikáciami Industry 4.0 vďaka Beckhoff panelu. Nízke prevádzkové náklady: Vďaka švajčiarskej kvalite si užívajte nízke servisné náklady počas celej životnosti zariadenia. Brúska na stredové otvory série Zentroflex SA je určená na vysoko presné valcové brúsenie v letectve, automobilovom priemysle a strojárenstve. Zentroflex SA je zároveň ideálne riešenie na obnovu dielcov po deformácii po tepelnom spracovaní alebo na zníženie nákladov na valcové brúsenie. Pohyb v osi Z zabezpečuje servomotor v CNC režime. Nakladanie, vykladanie a upínanie obrobku je manuálne. Nastavenia sa vykonávajú cez CNC panel a spustenie brúsenia prebieha stlačením tlačidla štart. Počas brúsenia nie sú potrebné ďalšie manuálne zásahy alebo nastavenia. Pre viac informácií nás kontaktujte.
