Quirlig-Schleiftechnik: Profitieren Sie vom optimierten Schleifprozess mit der Quirlig-Schleiftechnik. Korrekt geschliffene Zentrierbohrungen mit kreuzschraffiertem Schleifbild sorgen für Ölhaltefähigkeit, wenn das Werkstück zwischen Spitzen während des Rundschleifprozesses gespannt wird. Die Mikrostuktur sorgt für einen dünnen Ölfilm, der unerwünschten „Trockenlauf“ vermeidet. Intuitives Voll-CNC-Bedienpanel: Nutzen Sie das vollständige CNC-Bedienpanel (Beckhoff), um sämtliche Achsen der Maschine, die Roboterbeschickung sowie die automatische Abrichtung zu steuern. Speichern Sie alle Schleifprogramme und überwachen Sie Maschinenlaufzeiten, Effizienz und Fehlerstatus bequem. Dwjdpju Nmi Nefx Admjf Industrie 4.0: Vollständig kompatibel mit Industrie 4.0-Anwendungen über das Beckhoff-Bedienpanel. Niedrige Wartungskosten: Profitieren Sie von dauerhaft niedrigen Wartungskosten dank schweizerischer Qualitätsfertigung. Die Zentroflex A-Serie der Zentrierbohrungs-Schleifmaschinen ist konzipiert für hochpräzises Rundschleifen im Bereich Luftfahrt, Automotive und Maschinenbau, insbesondere bei Serienfertigung. Zudem ist sie die ideale Lösung, um verzogene Bauteile nach Wärmebehandlung zu regenerieren oder Rundschleifkosten deutlich zu reduzieren. Mit 6-Achs-Roboterarm und Servoantrieben auf allen Maschinenachsen arbeitet die Zentroflex A-Serie vollkommen autonom. Alle Be- und Entladevorgänge werden vom Roboter übernommen. Alle Achsbewegungen erfolgen durch Servomotoren. Konusabrichtung und Kompensation laufen ebenfalls automatisch ab. Sämtliche Bewegungen und Messvorgänge werden über das CNC-Bedienpanel verwaltet.
