Machining metals requires the implementation of special fluids. Known as “metalworking fluids” (MWFs), they are chosen with care to address the specific needs of the metalworking process. While it is possible to employ a basic MWF to achieve a certain result, industries have found a better option. They use chemical additives. Additives for metalworking fluids are available in diverse types for singular or multiple purposes. Choosing one over another requires knowing and understanding how certain factors influence the intended goal.
Four Factors Impacting the Selection Process
Before using any of the many currently available additives for metalworking fluids, it is imperative to look at the factors that will impact the result. These consist of the following four:
- The metal substrate: What is the metal (or metals) the MWF and its additive will interact with?
- The base oil or metalworking fluid: What is the chemical composition of the base MWF? Is it an emulsion-type MWF? Is it a synthetic MWF?
- The application: What is the purpose of employing the MWF? How is it to be applied?
- The properties sought after: What properties is the additive to enhance, decrease or include in the base oil? Is it improved lubricity or enhanced corrosion protection?
Awareness Is Key
Having awareness is crucial. Industries, technicians and scientists must work together to ensure the accurate formulation of MWF. Moreover, they should possess comprehensive knowledge of the chemical composition of additives for metalworking fluids. This understanding guarantees the best outcome for all parties involved.
