The invention belongs to the field of
metal machining fluids, and discloses a heavy-load
metal machining total synthesis cutting fluid as well as a preparation method and an application thereof. The
total synthesis cutting fluid comprises the following components in percentage by weight: 20%-30% of mixed
alcohol amine, 6%-9% of anti-
rust agents, 4%-6% of special amine, 6%-10% of lubricating agents, 15%-25% of extreme pressure agents, 6%-10% of cosolvents, 1%-2% of water-
softening agents, 1%-3% of
corrosion inhibitors and the balance of water. The
total synthesis cutting fluid disclosed by the invention has excellent lubricating extreme pressure property, can meet the requirement for heavy-load
machining, namely reaming, drilling, tapping, threading,
broaching, thread machining and the like, of difficult-to-
machine materials, namely high-temperature
alloy steel, a
titanium alloy and the like; a product is green and environment-friendly without containing
boron,
sodium nitrite, secondary amine,
chlorine,
phenol,
formaldehyde,
heavy metals and the like; in addition, the total synthesis
cutting fluid disclosed by the invention has excellent anti-
rust property, biological stability and machining property, and can enhance the surface quality of a machined part, prolong the service life of a cutter and reduce the
rejection rate, thus improving the production efficiency.
