SECTION 3.0
Today's cutting fluids are tailor-made tools that require careful selection. They contain a wide choice of special chemical agents designed to supply a definite degree of lubricity, surface activity, stability activity, stability, and anti-weld properties.
An effective coolant should:
- cool the work-piece and the tool,
- reduce friction,
- provide anti-weld properties,
- wash away chips,
- protect the work from rusting, and
- reduce wear.
All metalworking fluids eventually become contaminated and require disposal, even if the user has selected a high-quality fluid and has practiced proper fluid management. With this in mind, some simple coolant-system cleanout procedures will also be recommended which can extend coolant and tool life, as well as improve the entire broaching operation. |
