Problems solved by technology

Cutting has always been the main manufacturing method of aero-engine parts, but due to the characteristics of titanium alloys, it is more complicated and difficult to process than ordinary alloy steel. During the processing of parts, due to its superior mechanical properties at room temperature and high temperature, making Its machinability is very poor. In the cutting process, the cutting force is large, the cutting temperature is high, and the work hardening phenomenon is very serious. It is easy to stick to the knife during cutting, the tool wear is severe, and the tool life is low. Therefore, the lubricant used in the process is directly related to Machining accuracy of parts and tool life
[0003] At present, the lubricant (molding oil) used in the processing of aviation titanium alloy parts has poor chemical stability and relatively weak lubricating ability, so that the precision of the processed parts is not high, and the fatigue resistance is poor. Shows cracks and the cutting edge and the working area of ​​the workpiece are not smooth enough, the tool can only maintain a short cutting time, can not achieve better tolerances and more output, the tool life is short, waste liquid treatment is difficult, and it is not conducive to environmental protection

Abstract

The invention discloses a special forming oil for processing of titanium alloy aviation parts. Raw materials for the forming oil comprise highly refined low-viscosity base oil, an inactive lubricant, modified plant-based synthetic ester oxidized sunflower seed oil, nanometer graphite powder and an arylamine anti-oxidant. The special forming oil provided by the invention has high chemical stability, a high-strength oil film, lubricity and unique polarity properties, which ensures that the special forming oil has lubrication capability in processing of titanium alloy; the special forming oil has extremely strong thermal stability and oxidation resistance and does not contain substances like halogen, heavy metals, sulfur, phosphorus and silicon; a part processed by using the special forming has high precision, presents no cracks when observed with a magnifier having a zoom ratio of 200, has an anti-fatigue grade of 1++, and the service life of a cutter is prolonged; all the indexes of the forming oil reach or exceed relevant indexes regulated in GB6144-2010; an oil change period of a concentrated oil pool exceeds 15 months, an oil change period of a single machine oil pool exceeds 12 months, so treating and discharging of waste liquid are reduced and environment is protected.

Description

technical field [0001] The invention relates to a metal lubricant, in particular to a molding oil specially used for processing aviation titanium alloy parts of aero-engines. Background technique [0002] Titanium is an important structural metal, and titanium alloys are widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. Titanium alloys are mainly used in aircraft engine compressor components, such as forged titanium fans , Compressor disks and blades, cast titanium compressor casings, intermediate casings, bearing housings, etc. The spacecraft mainly uses the high specific strength, corrosion resistance and low temperature resistance of titanium alloys to manufacture various pressure vessels, fuel storage tanks, fasteners, instrument straps, frames and rocket shells. Due to the confidentiality and advanced nature of high-end technology, there are many blank spots in the field of aviation manufacturing in China...
