1, the total synthesis of class DC-506: water solution is cutting fluid with water as the main component of. Thermal conductivity and water cooling effect is good, but the pure water is easy to rust, poor lubrication. Therefore, often adding a certain amount of additives in aqueous solution, such as antirust additive, surfactant and oil additive, which has good rust resistance, but also has certain lubrication performance. In the preparation of water solution, we must pay special attention to the quality, if it is hard water, must be purified.


2, semi synthetic DC-507: semi synthetic solution is 95% ~ 98% of the water dilution and translucent liquid, has the good performance of the cooling / lubrication / rust.


3, the emulsion type class DC-503: is the solution with 95% ~ 98% water dilution and was emulsified with opaque liquid, has good lubrication and anti rust performance, less than half of synthetic cooling.


Selection of cutting fluid


1, the rough machining rough machining cutting fluid, machining allowance, the amount of cutting, the cutting heat. Semi synthetic cutting fluid using high-speed steel cutter cutting, the main purpose of the use of cutting fluid is the cutting temperature and reduce tool wear. Using low concentration emulsion or semi synthetic. It must be continuous, full cast, cemented carbide at high temperature so as not to produce huge internal stress and cracks.


2, finishing with precision machining cutting fluid requirements, smaller surface roughness, general selection of cutting fluid better lubricating properties, such as high concentration emulsion.


3, according to the nature of the workpiece material selection of cutting fluid cutting brittle materials such as cast iron, brass, commonly used synthetic or semi synthetic cutting fluid, so as not to break the chip adhesion in moving parts of the machine on. Processing of high strength steel, high temperature alloy and other hard materials, because the cutting process is in extreme pressure lubrication friction state, it should use cutting fluid containing extreme pressure additives. Cutting nonferrous metal and copper, Aluminum Alloy, in order to get a higher precision and surface quality, can use 10% to 20% of the emulsion, but can not be used for cutting liquid sulfur, sulfur corrosion to nonferrous metals. The cutting of magnesium alloy, not water solution, so as to avoid burning.
