Description
Technical field
The invention belongs to intermetallic composite coating lubricating oil field, be specifically related to a kind of aerolite high-speed milling water-soluble environment protective machining oil and preparation method thereof.
Background technology
Common Milling Process adopts lower speed of feed and larger cutting parameter, high-rate wireless LAN then adopts high speed of feed and little cutting parameter, and high-rate wireless LAN has high-level efficiency, high precision, high surface quality and can process the advantages such as high hard material for common Milling Process.In view of High-speed machining possesses above-mentioned advantage, High-speed machining is just used widely in Making mold, is processed as the main application end of new technology especially with aerial metal accessory, and progressively Substitute For Partial ground finish and electromachining.But, the conditions such as aviation alloyed aluminium workpiece should meet nothing interference, collisionless in high-rate wireless LAN process, smooth, cutting load is level and smooth, and these conditions cause high-speed milling to propose particular requirement in the main shaft of cutter material, cutter structure, cutter clamping and lathe, machine tool structure, Feed servo system and CNC system, wherein as possessing lubrication, cooling, cleaning and lubricant---the machining oil of rustless property, be that high-speed milling technology applies one of requisite key element.
Summary of the invention
One aspect of the present invention is to provide a kind of aerolite high-speed milling water-soluble environment protective machining oil, and this machining oil possesses excellent oilness.
The invention provides a kind of aerolite high-speed milling water-soluble environment protective machining oil, comprise base oil, Ethylhexyl stearate, polyglycerol fatty acid ester and Yatall MA.
Above-mentioned Ethylhexyl stearate has another name called stearic acid monooctyl ester, octadecanoic acid-2-(ethyl hexyl) ester, ethylhexyl stearate, octanol stearate, stearic acid 2-ethylhexyl, and its English name is 2-ETHYLHEXYLSTEARATE, and molecular formula is C
