In metalworking, cooling and lubrication are essential, making cutting fluids indispensable. In addition to selecting high-quality fluids, proper maintenance and management are equally important. During daily use, machining customers often face issues like fluid degradation, unpleasant odors, or rusted parts. Here, Taiwan Fimitech Co., LTD. provides five practical tips to help you easily manage cutting fluid quality.
- Maintain Proper Concentration and Use Clean Water
The main cause of odor is the presence of large amounts of bacteria in the cutting fluid. When preparing the fluid, do not dilute it too much and use clean water instead of groundwater. This prevents bacterial growth and improves lubrication performance. - Monitor and Adjust pH
Bacteria growth is inhibited when the cutting fluid pH is maintained between 8.5 and 9.5. Regularly replenish with fresh cutting fluid to maintain pH and extend fluid life. If odor occurs, our professionals can visit your site to assess remedial actions. If recovery is not possible, replace the fluid in the tank. - Remove Contaminants from Machine Leaks
Oil leaks from the machine (e.g., slideway oil, hydraulic oil) can mix with cutting fluid, causing emulsification and bacterial growth. We recommend using oil-water separators or filtration devices to remove contaminants. Taiwan Fimitech Co., LTD. provides high-efficiency centrifugal purifiers and chip collectors to effectively filter floating oil, dust, and sedimented metal chips, helping extend cutting fluid life. - Avoid Poor Operational Habits
Prevent contamination caused by operators, such as throwing cigarette butts, trash, or food into the cutting fluid. - Ensure Machine Cleanliness and Quality Control
Maintaining cleanliness of the machine and tank is critical for cutting fluid longevity. During fluid replacement, thoroughly clean the tank and machine. If necessary, add biocides to improve fluid quality. If the fluid cannot be restored, replace it with higher-quality cutting fluid.
