What should I do if the cutting fluid has deteriorated?

Q: After using our cutting fluid for several weeks, it starts to deteriorate and produce an odor. What should we do? Is it a product issue?

A: It isn’t necessarily a product defect. The problem may stem from your operating environment, concentration control, or the cleanliness of your sump. PAOLUBE offers a full suite of after-sales services to help you address this issue, including:

  • On-site technical support:
    When you notice foul odors or excessive foaming, we can dispatch specialists to your facility for diagnostics and to identify the root cause.

  • Formulation adjustment & biocide solutions:
    Our technical team can recommend appropriate biocides and adjust the cutting-fluid formulation to suit your plant’s water quality and equipment conditions.

  • Cleaning & maintenance recommendations:
    We’ll assess whether your oil-water separation system and circulation tank need cleaning, and we’ll suggest suitable equipment—such as magnetic filters or centrifuges—to keep your fluid in top condition.

Tip: The life span of cutting fluid is closely tied to water quality, concentration control, sump cleanliness, and tramp-oil removal. Regular maintenance and monitoring are key to ensuring stable machining and reducing costs.
