What kinds of precision CNC metal cutting fluids are there?
Cutting fluid is an industrial fluid used to cool and lubricate tools and workpieces during metal cutting and grinding.
What kinds of metal cutting fluids are there?
In the cutting fluid, the main component of the aqueous solution is the water cooling performance liquid, which is also convenient for the operator to observe during machining; Emulsion is mainly made of mineral oil and emulsified ointment diluted by 95% - 98% water. It has good fluidity, cooling property and low lubricating performance. Emulsion combines the advantages of oil and water, and has good lubricating and cooling properties, so it has a better effect on metal cutting at high speed, high temperature and low pressure.
In addition to cutting difficult to machine materials, emulsion can also be used for all light and medium load cutting and most heavy load machining, and emulsion can also be used for all grinding except for complex grinding. However, the disadvantages of emulsion are also very prominent. When contacting with air, it is easy for bacteria to multiply, which will corrupt and deteriorate the emulsion. Therefore, organic bactericides with weak toxicity should be added generally. High concentration emulsion is used for rough turning and grinding.
Low concentration emulsion is used for fine turning, drilling and milling; Cutting oil is mainly mineral oil, and only a few animal and vegetable oils or composite oils are used. In actual use, additives are added to improve its lubrication and rust prevention performance. Its lubrication performance is excellent, but its cooling performance is poor. It is mainly used for gear processing, milling, reaming, machining, etc.
