What kind of cutting fluid should be used according to the workpiece material, the difficulty of processing technology, processing mode, processing conditions and so on to do a comprehensive analysis to choose.

1, steel tool

Its heat resistance temperature is about 200-300℃, can only be applied to the cutting of general materials, will lose hardness at high temperature. Because of the poor heat resistance of the tool, the cooling effect of the coolant is better, generally using emulsion is appropriate, the use of the American emulsion cutting fluid M16 or M16-A can fully meet the requirements.

2, high speed steel tool

This material is a high-grade alloy steel based on chromium, nickel, tungsten, molybdenum, vanadium (and sometimes aluminum), which is significantly more resistant to heat than tool steel, with a maximum allowable temperature of 600 ° C. Compared with other high temperature resistant metal and ceramic materials, high speed steel has A series of advantages, especially it has high toughness, suitable for the complex workpiece geometry and continuous cutting, and high speed steel has good machinability and price are easy to be accepted, use add beauty and synthetic water-based cutting fluid M20 - A or M21 can meet the requirements.

Hard alloy steel cutting tool

The hard alloy used for cutting tools is composed of tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) and 5-10% cobalt. Its hardness is much higher than that of high-speed steel, the maximum allowable operating temperature can reach 1000℃, with excellent wear resistance, in the processing of steel materials, can reduce the bonding phenomenon between chips. Use Gamey semi-synthetic water based cutting fluid MS45 or 46.

4. Ceramic cutting tools

Alumina, metal and carbide sintered at high temperature, the high temperature wear resistance of this material is better than cemented carbide, generally using dry cutting, but considering uniform cooling and avoid high temperature, also often use water-based cutting fluid.

5. Diamond cutting tools

Very high hardness, generally used in cutting. In order to avoid high temperature, also like ceramic materials, water-based cutting fluid is used in many cases.

Of course, what kind of cutting fluid should be used according to the workpiece material, the difficulty of processing technology, processing mode, processing conditions and so on to do a comprehensive analysis to choose.
