Description
Technical Field
The invention relates to a water-soluble stainless steel cutting fluid, in particular to a preparation process of a water-soluble stainless steel cutting fluid with high thermal conductivity.
Background
Stainless steel has the advantages of high strength, high wear resistance, low expansion coefficient and the like, and is widely applied to industrial departments of machinery, petrochemical industry, electronic instruments, national defense and the like. The cutting fluid has the characteristics of large cutting force, high cutting temperature, serious knife sticking phenomenon and strong work hardening tendency. Due to the cutting characteristics, the stainless steel has the phenomena of large cutting power consumption, high cutting temperature, short service life of a cutter, low surface quality of a machined workpiece and the like in the cutting process.
The stainless steel material has low heat conductivity and serious high-temperature hardening phenomenon, and the cutting heat generated in the cutting process cannot be timely removed, so that the temperature of the surface of a workpiece and the surface of a cutter is increased, and the cutting fluid for the stainless steel can be divided into two categories of water-insoluble cutting fluid and water-soluble cutting fluid. The cooling efficiency of the oil-soluble cutting fluid is low in terms of cooling property. For stainless steel cutting, the oily cutting fluid is not easy to be effectively cooled due to the characteristic of low heat conduction point.
Although the conventional water-soluble cutting fluid has a good cooling performance and is more than enough to be applied to conventional metal cutting, the cooling performance needs to be further improved compared with stainless steel, so that the heat conductivity coefficient of the cutting fluid needs to be improved, and the temperature generated in the cutting process is increased due to the insufficient lubricity of the water-soluble cutting fluid, so that the cutting fluid for stainless steel needs good lubricity and good heat conductivity.
In view of the above, there is a need for a highly heat conductive, water-soluble stainless steel cutting fluid with good lubricity to overcome the deficiencies of the prior art.
Disclosure of Invention
