Nickel-based alloy high-speed grinding fluid

Abstract

The invention discloses a nickel-based alloy high-speed grinding fluid formula, which comprises the following components by weight: 5-10 parts of an extreme pressure anti-wear agent, 20-30 parts of analkali reserve agent, 5-15 parts of an antirust agent, 0.5-4 parts of a corrosion inhibitor, 1-5 parts of a penetrating agent, 0.5-2 parts of an air release agent and 40-50 parts of deionized water.The extreme pressure anti-wear agent is at least one of mercaptothiadiazole or sodium mercaptothiadiazole. By adding the extreme pressure anti-wear agent into the formula, the friction coefficient ofthe grinding fluid can be remarkably reduced, the diameter of a grinding spot is increased, and the surface friction efficiency is improved; the prepared nickel-based alloy high-speed grinding fluid has excellent lubricating performance, abrasion resistance and defoaming performance, the high-speed grinding requirement of nickel-based alloy can be met, the surface smoothness of a prepared nickel-based alloy workpiece is high, and the service life of a grinding wheel is long. The invention further discloses a preparation method of the nickel-based alloy high-speed grinding fluid, the preparation method is simple and convenient, and the nickel-based alloy high-speed grinding fluid can be used for industrial batch production.

Description

technical field [0001] The invention relates to a grinding fluid, in particular to a high-speed grinding fluid used for lubrication of nickel-based alloy grinding. Background technique [0002] As an important basic material for load-bearing connections, nickel-based alloy materials play an indispensable role in the connection of various parts and play an important role in the manufacture of high-end equipment in the fields of nuclear power, aerospace, energy, chemical industry, and agricultural machinery. With the rapid development of my country's high-speed rail, nuclear power, aerospace and other industries, the nickel-based alloy materials used usually have comprehensive properties such as high strength, high temperature resistance, high fatigue resistance, high corrosion resistance, and high reliability. Most nickel-based alloy materials need to be polished before delivery. When ordinary grinding fluid is used for grinding nickel-based alloys, there are problems such a...

Problems solved by technology

When ordinary grinding fluid is used for grinding nickel-based alloys, there are problems such as large grinding force, high grinding temperature, severe work hardening, low grinding efficiency, and unsatisfactory finished product quality.

However, the research on nickel-based alloy grinding and high-speed grinding machine tools in my country started relatively late, and the current main research work is still focused on the mechanism of high-speed grinding, and there are very few studies on the high-speed grinding fluid used in conjunction with it.

[0003] At present, the domestic existing total synthesis technology mainly uses fatty acids containing carboxyl groups such as oleic acid, tall oil, and self-emulsifying esters as the main lubricants, which are prone to generate a large amount of foam during high-speed grinding, resulting in insufficient lubricity and grinding. If the cutting temperature is too high, the surface of the workpiece will be burned; the other is to use polyethylene glycol 400, polyethylene glycol 600, conventional polyether, block polyether or trans-block polyether as lubricants, which are relatively carboxyl-containing Fatty acid lubricants have relatively low foam, but their polarity is weak, and they are not easy to penetrate into the workpiece and the action point of the abrasive tool during high-speed grinding, and the air is released slowly, resulting in Airflow barrier, low grinding efficiency, poor workpiece surface quality
