Example from a steel
component manufacturer.
Initial Investigation concluded:
 | Customer was using a product with poor
bio-stability, which had required regular treatment with large doses of
various biocides. |
| Several operators had become sensitive
to common biocides used in most metal-working fluids. |
| Surface finish was only adequate. |
| Corrosion of components after machining
was leading to additional process time as components had to be dipped in
corrosion inhibitor. |
Recommendation:
| Use a hazard-free metal working fluid,
which was free from formaldehyde, amine, and boron. |
| Ensure product has good residual film
corrosion protection. |
| Institute a coolant monitoring system. |
Results:
| No operator comfort problems. |
| Improved surface finish. |
| Reduction in corrosion. |
