Cutting fluid foam causes and solutions

What causes excessive froth in cutting fluid? 

1, the liquid level is too low, 

2, the working pressure is too high, 

3, the water is too soft, 

4, the cutting fluid concentration value is too high, 

5, gas into, 

6, production and processing machinery and equipment design shortcomings, 

7, the cutting fluid characteristics is not good.

Cutting fluid produces too much foam, will immediately affect the quality of metal laser cutting processing, 

high efficiency and behind the maintenance and production costs. 

In the laser cutting processing production and manufacturing of metal materials, 

it is particularly important to select high quality cutting fluid, whether in water hardness or 

soft water to maintain the activity and low bubble characteristics, 

so that the laser cutting machining effect of metal materials is maintained for a long time.

The selection of high-quality cutting fluid with low bubble technology and suitable for high 

liquid supply working pressure environment is conducive to reducing the generation of foam, 

such as a high-performance, no chlorine and sodium nitrite, with reliability of semi-formed water 

soluble cutting fluid commodity, with low foam, strong water adaptability and other roles. 

In addition, foam generation can be reduced in the application of cutting fluid by maintaining 

effective liquid level, working pressure and formulating concentration values.
