How to choose the suitable cutting fluid according to the cutting tool material?

　 In general the use of what kind of cutting fluid should be based on the processing of the workpiece materials, processing technology, the degree of difficulty, processing methods, processing conditions, such as doing a comprehensive analysis to choose.
Steel cutter
The heat resistant temperature is about 200-300 DEG C, which can only be used in the cutting of general materials, and will lose the hardness at high temperature. Because of the poor heat resistance of the tool, the cooling effect of the cooling liquid is better.
HSS Tool
This material is based on chromium, nickel, tungsten, molybdenum, vanadium (some also contain aluminum) based on advanced alloy steel, their heat resistance is significantly higher than the tool steel, allowing the maximum temperature of 600 degrees C. And other high temperature of the metal and ceramic materials, has a series of advantages of high speed steel, especially it has high toughness, suitable for complex workpiece geometry and continuous cutting, and high speed steel with workability and good price on the acceptable use of water-based cutting fluid can meet the requirements.
Carbide tool
For hard alloy cutting tool is made of tungsten carbide, titanium carbide (WC) (TiC), tantalum carbide (TaC) and 5-10% Co, which greatly exceeded the hardness of high speed steel, maximum allowable working temperature is 1000 degrees centigrade, has excellent wear resistance, in the processing of iron and steel materials, can reduce the phenomenon of cutting chip bonding between. Using semi synthetic cutting fluid.
Ceramic tool
Using alumina, metal and carbide in high temperature sintering, high temperature wear resistance of this material is better than the hard alloy, with dry cutting, but considering the uniform cooling and avoid high temperature, often use water-based cutting fluid.
Diamond tools
Has a very high hardness, generally used in cutting. In order to avoid the temperature is too high, but also like ceramic materials, in many cases the use of water-based cutting fluid.
