Plan d'entretien de la broche hydrostatique : huile, filtre et surveillance

Key Takeaways:

A hydrostatic spindle rewards discipline, not heavy service. The routine is simple: keep oil NAS 5 clean, change it around 2000 h or six months, service the filter ~500 h, and monitor pressure, flow, and film.

Plan d'entretien de la broche hydrostatique : huile, filtre et surveillance

Léger mais régulier

Les broches hydrostatiques n'ont pas de pièces d'usure; l'entretien protège le film.

Plan

  • Propreté NAS 5 en permanence.
  • Changement d'huile ~2000 h ou 6 mois.
  • Filtre ~500 h.
  • Avant marche: pression, débit, film nominaux.
  • Température 35±5°C.

Pourquoi

La discipline maintient défaut ≤0,1 μm et raideur >500 N/μm toute la vie.
