With the rapid development of modern manufacturing, the role of cutting fluid in the machining process is becoming more and more important.
However, impurities in the cutting fluid such as chips,
Grinding wheel powder, etc., but it poses a potential threat to the service life of the tool and the machining quality of the workpiece.
According to authoritative research, reducing the impurities in the cutting fluid from 40 m to less than 2 m can extend the service life of the tool by 1 3 times.
This undoubtedly provides an important guiding direction for the manufacturing industry.
In order to achieve this, we must pay attention to the purification of cutting fluids.
In the process of precision machining or ordinary turning, grinding, milling, drilling and tapping, cutting fluid may be contaminated by a variety of substances, such as metal powder, grit fine powder, floating oil, microorganisms and their propaculars, etc.
Not only do these contaminants degrade the performance of cutting fluids, but they can also have an impact on worker health and the environment.
Solid powder contamination is a problem that cannot be ignored.
The solid powder in the cutting fluid is mainly used for the wear of machined parts and tools.
These powders are suspended in the cutting fluid, which can damage the tightness of the pump, increase the wear of the tool, affect the quality of the machining, and even injure the employees.
In addition, the solid powder coalesces with organic matter to form a precipitated layer, which provides favorable conditions for the reproduction of microorganisms, which in turn stabilizes the precipitated solids.
The solid powder in the cutting fluid is also highly chemically active, which can render certain components of the cutting fluid ineffective.
Floating oil pollution is also an important issue.
The loose sealing of the machine tool leads to oil leakage into the cutting fluid system, which makes some materials of the cutting fluid system expand and deform, interferes with the emulsion balance of the cutting fluid, and makes the cutting fluid lose stability.
At the same time, the floating oil often floats on the surface of the cutting fluid, which blocks the contact between the cutting fluid and the air, resulting in the lack of oxygen in the cutting fluid, making the rapid reproduction of anaerobic bacteria and accelerating the corruption and deterioration of the cutting fluid.
In addition to solid powder and floating oil pollution, microbial contamination is also a problem that cannot be ignored.
Bacterial contamination can rancidize the cutting fluid, while sticky material from mold growth can cause clogged lines and nozzles.
These microorganisms not only affect the performance of the cutting fluid, but also may cause secondary pollution to the workpiece and affect the machining quality.
In the face of these pollution problems, the use of cutting fluid purification equipment is an effective way to solve the problem.
The cutting fluid purification equipment can quickly remove solid particles from the cutting fluid by increasing the settling rate of particles and oil droplets through a powerful centrifugal position
Contaminants such as oil droplets and mold.
This not only cleans the cutting fluid, but also allows it to be reused back in the machine, improving machining efficiency and reducing costs.
Before starting work after the festival, the concentration and pH value of the working liquid should be closely monitored.
Once it is found that the concentration deviates from the range of use, it should be adjusted in time.
At the same time, the pH of the emulsion microemulsion should be maintained at 85-9.5. If there is any abnormality, take remedial measures in time.
The Chinese New Year is just around the corner, and the longest holiday of the year is about to begin.
On this occasion of celebration, don't forget to take care of the cutting fluid.
