The invention provides a quickly cooled machining cleaner, and particularly relates to the field of machining. The cleaner is prepared from the following raw materials in parts by weight: 4 to 6 parts of polyethylene glycol, 5 to 9 parts of potassium sodium tartrate, 7 to 11 parts of a lubricating oil additive, 4 to 7 parts of zinc naphthenate, 2 to 4 parts of diethylene glycol, 8 to 12 parts of disodium ethylate tetraacetic acid, 4 to 8 parts of polyacrylamide, 5 to 10 parts of mineral oil, 3 to 6 parts of an extreme pressure additive, 3 to 6 parts of an antioxidant, 4 to 10 parts of oil diethylene glycol ester, 6 to 9 parts of diisopropyl sodium sulfonate and 7 to 10 parts of castor amide. Through cooperation of all raw material components, the quickly cooled machining cleaner is obtained; the cleaner is extremely high in cleaning property and further can effectively reduce temperature of mechanical equipment, prolong the service life of the mechanical equipment and increase the economical benefit; moreover, the cleaner is high in biodegradability, can effectively remove oil dirt from the mechanical equipment, is harmless to the skin and is safe and environmentally-friendly.
