Problems solved by technology

[0004] At present, there are still some problems in the performance of cutting fluids available in the market for titanium alloy processing. The main disadvantages are: first, the poor lubricating performance, which leads to serious sticking of the tool during processing, short service life of the tool, and the surface of the processed titanium alloy workpiece The quality is difficult to meet the process requirements, which affects the production cost; second, the domestic titanium alloy cutting fluid is generally still using toxic and harmful substances such as mineral oil, sulfur, phosphorus, chlorine, boron, phenol, formaldehyde, secondary amines, heavy metals, sodium nitrite, etc., endangering Environmental Safety and Human Health

Description

technical field [0001] The invention belongs to the field of metal working fluids, and in particular relates to an environment-friendly titanium alloy semi-synthetic cutting fluid and its preparation method and application. Background technique [0002] Titanium alloy materials have become one of the most important engineering materials in the aerospace industry due to their small specific gravity and high strength, especially at high temperatures of 300-400 ° C and high corrosion resistance. It is widely used in the fields of shipbuilding, automobile, medical treatment, chemical industry and energy. However, titanium alloy is a typical difficult-to-machine material with poor cutting performance. Compared with other metal materials, titanium alloy has small deformation coefficient, high cutting temperature, large cutting force per unit area, and severe chilling phenomenon. Cutting features. Therefore, in addition to using reasonable tool materials, tool parameters, and cut...
