Recycling Methods for Cutting Medium in Automotive Engine Factories

Abstract

During the production process, a large amount of cutting medium is required for cooling, and these medium will be contaminated and aged over time, leading to a decrease in their performance. In order to reduce the generation of waste and resource consumption, recycling cutting medium has become the main solution. This study uses regeneration methods such as filtration, centrifugal separation, chemical treatment, and adsorption to regenerate and reuse cutting medium from automotive engine factories. This study evaluated the effectiveness and feasibility of the regeneration treatment method through comparative experiments and analytical tests. The experimental results show that the cleanliness of the cutting oil before regeneration is between 30% -35%, and after regeneration treatment, its cleanliness reaches 85% -93%. The regeneration treatment method can effectively remove suspended solids and dissolved impurities in the cutting medium, significantly improving its cleanliness.
