Additives for metalworking fluids

The ultimate purpose of a metalworking fluid is to provide cooling and lubricity to metal components whilst they are being machined or processed. Drawing heat away from the metal is vital in preventing welding of the tool to the piece. The metalworking fluid also acts as a physical barrier between metal surfaces, which reduces wear during processing to help prolong tool life and maintain surface finish. 

We understand the complexities around formulating metalworking fluids, and have developed a broad range of advanced components with a range of functionalities, depending on the desired fluid type.

Metalworking fluid types

There are three main types of metalworking fluid and the severity of the operation, machine speed and type of metal being worked dictates the type of metalworking fluid required. The table below summarises the fluid types.

(Water immiscible)                                              Water miscible
 Neat fluids  Semi-synthetic fluids  Synthetic fluids
  • For most demanding applications
  • Tend to be mineral oil/ester based
  • Simpler formulations.
  • Highly adjustable for medium to severe applications
  • Emulsion based (O/W or less commonly W/O)
  • Good cooling properties
  • Emulsion can be difficult to maintain.
  • Typically for less demanding applications
  • Water based solutions (no mineral oil)
  • Best cooling properties
  • Easiest to wash off and clean metal parts.

How can we help with metalworking fluid formulation?

Over the last 40 years, the wish list of the metalworking fluid formulator has remained relatively un-changed.  First and foremost is the need for multi-metal capability, obtaining improved aluminium lubricity but without sacrificing ferrous performance. Of near-equal importance is the need for a bio-resistant product that does not rely on heavy concentrations of biocides and fungicides.  Effective tramp oil rejection is necessary to maintain constant high-performance in the presence of lubricant contaminants and to minimize smoke and mist levels. These attributes can only be captured if the formulated product has a low foam profile – a formidable challenge unto itself.  

We supply a range of additives that can help make the formulator’s wish list a reality. Our range of Priolube™ and Emkarox™ base fluids provide outstanding lubricity and cooling and our emulsification portfolio offers the formulator emulsion stability, tramp oil rejection and extended fluid lifetime.

With our experienced technical experts available to offer support though each stage of the selection process, you can be confident that we have a solution to meet your requirements.
