The advantage and breakthrough of semi-synthetic cutting fluid defoamer

Semi-synthetic cutting fluids are widely used in lubrication and cooling to improve cutting performance and machining accuracy. However, the foam produced in cutting fluid often brings a series of problems, such as affecting cutting performance, reducing cooling effect and operating difficulty. In order to solve this problem, semi-synthetic cutting fluid defoamer has become a common and effective means.

Foam in the cutting process may bring some problems, such as:

1. Impact on cutting performance: when the cutting fluid produced a large number of foam, the foam may reduce the cutting fluid contact area and lubrication effect, resulting in decreased cutting lubrication performance, increased friction and wear, reducing machining accuracy.

2. Affect cooling effect: foam can hinder the heat transfer between cutting fluid and workpiece or tool, reduce the cooling performance of cutting fluid, resulting in workpiece overheating, tool life shortening and other problems.

3. Difficult to operate: a large number of foam will affect the cleanliness of the processing environment and work efficiency, increased cutting fluid spill and foam spatter problems.

Semi-synthetic cutting fluid defoamer can play the following roles:

1. Inhibition of foam formation: defoamer can reduce the surface tension in cutting fluid, destroy the formation of foam, thereby reducing the cutting fluid gas foam.

2. Accelerating the bursting and dissipation of foam: defoamer reduces the time and amount of foam in cutting fluid by reducing the stability of foam surface film.

3. Improve cutting effectiveness and accuracy: effectively control and reduce the foam in cutting fluid, facilitate the contact between cutting fluid and workpiece or tool, and improve lubrication and cooling effect, it is helpful to obtain better cutting performance and machining precision.
