Problems solved by technology

However, high concentration means more consumption of cutting fluid, which not only increases the comprehensive use cost of cutting fluid, but also increases the amount and difficulty of waste liquid treatment in the future
Some engine machining sites have also tried to reduce the concentration of cutting fluid used, but the result is either that the machining accuracy of the parts cannot meet the requirements, or the service life of the tool is reduced, or even broken
At the same time, due to the decrease in concentration, the cutting fluid is also prone to sudden bacterial problems, and a large amount of additional bactericides need to be added for maintenance, which increases maintenance costs.

Description

technical field [0001] The invention belongs to the field of metal processing, and relates to a metal processing fluid and its preparation method and application. Background technique [0002] After years of reform and opening up, my country's automobile industry has developed rapidly and formed a relatively complete production layout. Among them, the engine, which is a key component of the automobile, has become increasingly mature in R&D and production technology, and has a considerable scale. The engine is the heart of the car, and its structure is precise and complex, which requires extremely high machining accuracy. According to the main structure, it can be roughly divided into cylinder block, cylinder head, crankshaft, connecting rod, piston, camshaft and other components. Among them, the cylinder block and the cylinder head are both porous and thin-walled box structures. Among them, the machining of the cylinder head intake, the exhaust valve seat cone surface and ...
