About the use of coolant

The use of coolant has 4 effects:

Cooling effect: Due to the friction and impact between the circular saw blade and the stone during the cutting process, a lot of heat is generated on the cutting surface, and the heat dissipation of the stone is poor, so that most of the heat is absorbed by the saw blade, especially the diamond knife The head is the first to bear the brunt, which is very easy to cause graphitization of the diamond, and the cutter head is also easy to be burned and easy to fall off. At the same time, the steel matrix is also prone to thermal deformation and cracking from the root of the nozzle. Continuously spraying a large amount of coolant to the incision from the front and back and both sides of the saw blade will play a very good role in cooling and protecting the saw blade;

Chip punching effect: When the coolant rushes to the incision with a certain pressure (generally required hydraulic pressure greater than 0.1MPa), a large amount of material chips will be taken away, which is of great benefit to reducing the secondary wear of the chips and the diamond cutter head and matrix. Other

Lubrication: If an emulsion-type coolant is used, the hydrophilic and lipophilic properties of the emulsifier can make the surface of the saw blade and the rock surface adhere to a layer of lubricating oil, which can reduce the friction coefficient during sawing, thereby reducing Cutting resistance, reducing vibration.

Dust reduction effect: It can effectively reduce the splash of dust, avoid the human body inhaling dust and form pneumoconiosis, which is beneficial to the health of workers, reduces air pollution, and is conducive to environmental protection.

The cooling liquid is generally cooling water, or an appropriate amount of rust inhibitor and an emulsifier can be added to the cooling water (add saponified dissolved oil, swire oil and other hydrophilic and lipophilic emulsifiers)
