When is the car knife not using the coolant?
Not all tool to cooling fluid, generally low speed operation tool requires coolant, even alloy cutter machining metal parts at low speed, many will prepare some coolant or water. This is your specific environment, which is like what texture and hardness of a car, what texture and the size of the label.
Normal hard alloy cutting tools do not open coolant, and the cooling fluid can make the tool not very hot and cause the blade to crack. But at the very beginning when processing plus, fully cooling fluid can be cooled sufficiently is heated unevenly, with high speed steel (commonly known as white steel) what circumstance can add coolant,
It depends on your tool is to belong to that type of material, also want to see the using objects, white steel knife with a cooling fluid commonly, because it belongs to the low speed props, capricious, low brittleness, commonly used for picking thread, such as without coolant blade soon burn. Alloy steel cutter, generally without coolant, because it belongs to high speed cutter, used for metal cutting, speed between 350-1200 revolutions, hardness of the cutting tools is very high, but very crisp, fell on the ground fall can cause the blade.
