What we need to do to use cutting fluid based on a comprehensive analysis of the processing of the workpiece material , ease of processing , processing methods , processing conditions , such as working conditions go choice.
1 , steel knives
Its heat resistant temperature of between about 200-300 ℃, generally only suitable for cutting the material at high temperatures will lose hardness. Because of this poor heat resistance tool , requiring better cooling effect of the cooling liquid , an emulsion is preferably used in general , the use of additional coolant Breasts M16 or M16-A can completely meet the requirements.
2 , high-speed steel cutting tools
This material is chromium, nickel, tungsten, molybdenum , vanadium ( some also contain aluminum ) alloy based on advanced , their heat resistance significantly higher than tool steel , up to the maximum allowable temperature 600 ℃. Compared with other high-temperature metal and ceramic materials , high-speed steel has a number of advantages , particularly its higher tenacity , suitable for complex geometry of the workpiece and continuous machining, and high-speed steel has good machinability and the price likely to be accepted , using the Canada-US semi-synthetic water-based cutting fluid M20-A or M21 to meet the requirements .
3 , carbide steel knives
Carbide cutting tools are used by the tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) , and 5-10 % of cobalt , it is much higher than the hardness of high speed steel , the maximum allowable working temperature of up 1000 ℃, with excellent wear resistance , in the processing of iron and steel materials , can reduce inter- chip bonding phenomenon . Using the Canada-US semi-synthetic water-based cutting fluid MS45 or 46 can be.
4 , ceramic knives
Alumina , metal and carbide sintered at high temperatures from high-temperature wear resistance of this material is even better than carbide , commonly used dry cutting, but considering the uniform cooling and to avoid overheating , often using water-based cutting fluid.
5 , diamond tool
Has a very high hardness, generally used in the cutting . To avoid overheating , but also as a ceramic material , as in many cases the use of water- based cutting fluids down .
Of course , the use of cutting fluids what we need to do a comprehensive analysis based on the processing of the workpiece material , ease of processing , processing methods , processing conditions , such as working conditions go choice.
