Some possible reasons are – low liquid level, deposition of iron chips, etc. The above could lead to poor fluidity and cause an increase in contact area of cutting fluid and air which results in foaming.
Add cutting fluid on frequent basis. Please note the angle of the nozzle when applying it and avoid direct flushing at the right angles. This can reduce the chance of foaming.
The primary cause of odor is the large amount of bacteria in cutting fluid. We would suggest using clean water to blend with lubricants. This will prevent the bacteria from breeding and will increase the lubricity.
The bacteria will be inhibited when the PH value is in between 8.5 and 9.5. Thus, it is recommended to add new lubricants to maintain the right PH value. Apart from this, to extending the life of cutting fluid, we would suggest the use of centrifugal water-oil separator or chip removal machine to remove tramp oil and sludge.
Our specialists would be pleased to visit the site and evaluate for remedy if needed. If the issues remained unsolved, the cutting fluid in the sink will need to be replaced.
Possible causes for skin allergies:
- The cutting fluid contains too much bacteria
- PH value of cutting fluid is overly high
- The personnel has sensitive skin or allergies.
It is recommended to wear gloves and working suit during the operation process to avoid direct contact with cutting fluid. In addition, keep an eye on the PH value and add new lubricants as needed to prevent bacteria from breeding.
Slowly pour the oil into water and blend evenly. Do not pour oil in first and add water for blending. The ratio for blending can be adjusted depending on the conditions.
Metal cutting fluid may change color due to various reasons during its usage. Here are some common factors that can cause the color change in metal cutting fluid:
Metal Particles and Corrosion: During metal processing, metal cutting fluid may come into contact with metal particles or corrosion byproducts. These metal particles or rust can cause the fluid to change color, such as appearing gray, black, or brown.
High-Temperature Oxidation: Metal cutting fluid can undergo oxidation reactions in high-temperature environments, leading to a change in color. This oxidation can result in the fluid appearing yellow, brown, or black.
Microbial Growth: The presence of water and organic components in metal cutting fluid provides an environment for microbial growth. If microbial contamination occurs, such as bacteria, mold, or algae, they can cause the fluid to change color, appearing green, blue-green, or cloudy.
Chemical Reactions: The components in metal cutting fluid might react chemically with other substances, producing new chemical compounds that lead to a change in fluid color.
Please note that regular inspection and maintenance of metal cutting fluid are recommended to ensure its quality and performance. If the discoloration persists or worsens, further analysis and action may be required to identify the root cause and take appropriate measures.
Lubricating oils: Excellent lubricity; on the downside, poor heat dissipation may lead to heavy load, oil mist, or poor air quality in the facility.
Cutting fluid: Excellent cooling effect that smoothens workpiece processing and provides better processing environment; on the downside, lower lubricity in comparison to lubricating oils.
