The invention relates to special synthesized
cutting fluid with ultra-high lubricating property for black
metal and a preparation method of the special synthesized
cutting fluid, and belongs to the technical field of
cutting fluid for
metal processing. The
cutting fluid consists of organic
alcohol amine, an antirust agent, extreme-pressure lubricants, boundary lubricants, a water softener, a
metal deactivator, a couplant, a bactericide, a
defoamer and water. The various extreme-pressure lubricants and the various boundary lubricants are combined organically, effective constituents soak in the
cutting fluid and the lubricating effect is achieved at different
processing temperatures and under different pressures, and the different lubricants have synergism, so that the
cutting fluid has ultra-high lubricating property. Practice proves that the cutting fluid can be used for
processing of
grinding, milling, turning, tapping, drilling,
honing and the like on workpieces made of materials such as
cast iron,
carbon steel,
alloy steel, stainless steel and even hard
alloy, can directly replace oil-containing cutting fluid in multiple situations, is
environmentally friendly, and is long in service life.
