Water based metalworking fluids must be properly mixed and maintained in the proper concentration range to maximize performance. When fluid concentrate and water are mixed to charge the machine’s fluid reservoir or central system, the fluid concentration must be tested to insure that the starting concentration is correct. The concentration can be measured with a refractometer, test strips or a chemical titration method. Concentration may be expressed as a percentage or as a ratio of the amount of metalworking fluid concentrate to the total volume of mix. Maintaining the recommended concentration range for your metalworking fluid will improve the overall performance of the operation, improve productivity, extend fluid life, reduce disposal costs, and improve overall operator satisfaction.
