Problems solved by technology

Due to the high chemical activity of titanium, it is easy to react with substances in the air at high temperature, which will cause serious chilling and hardening during processing, which will aggravate the wear of the tool
Moreover, the cutting force per unit area of ​​titanium alloy is large and the cutting temperature is high. The high affinity between titanium and most tool alloy elements will easily lead to the rapid loss of tool alloy elements. Rapid passivation, rapid tool wear and failure
[0004] At present, there have been researches on cutting oil for lubricating and cooling by spray supply method, but the cutting fluid used at present is generally general-purpose cutting oil, which can be used in the cutting process of ordinary steel, aluminum, copper and other relatively low cutting temperatures. For titanium Alloy is a difficult-to-machine material. These lubricating oils cannot withstand the high temperature during cutting, and the formed lubricating oil film is easily destroyed at high temperature, which seriously affects the service life of the tool and the surface processing quality.

Abstract

The invention provides trace lubricating cutting oil for processing titanium alloy. The trace lubricating cutting oil is prepared from the following ingredients in parts by weight: 3 to 16 parts of Guerbet alcohol, 2.5 to 14 parts of trimethylolpropane oleate, 0.25 to 4 parts of organic phosphate and / or sulphur bearing extreme-pressure additives and 1 part of high-base-number sulphonate. The trace lubricating cutting oil for processing titanium alloy has the advantages that high temperature can be resisted; the cutting temperature is low; the lubricating effect is good.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a minimal lubrication cutting oil for processing titanium alloys. Background technique [0002] In the cutting of titanium alloys, cutting fluid or processing oil is usually used, the purpose of which is to prolong the life of the tool, improve the surface accuracy of the processed workpiece, reduce the wear of the tool, and reduce the temperature in the cutting area, so as to improve the processing efficiency. s efficiency. [0003] Titanium alloy is a difficult-to-machine material. Titanium alloy has high high-temperature strength, high cutting temperature during cutting, low thermal conductivity, and short contact length between tool and chip. Cutting heat is difficult to dissipate, and most of the cutting heat is transmitted to the tool. Due to the high chemical activity of titanium, it is easy to react with substances in the air at high temperature, which will cause ser...
