The customer used a certain cleaning agent with a small ultrasonic machine at a concentration of 10%, 70 degrees, and cleaned it for 10 minutes. However, there was still an issue with the bottom of the feedback hole not being cleaned properly, and the rust prevention effect did not meet the standard.

Environmental and resource issues are two major themes that human society urgently needs to address in order to achieve sustainable development. Metal working fluids have been widely used with industrial modernization. However, due to the consumption of large amounts of petroleum resources, relatively high operating and maintenance costs, and short service life of emulsified oil and semi synthetic liquids, fully synthetic metal working fluids with long service life, transparent and visible processing, good stability, and certain cleanliness are increasingly recognized and applied.

Magnesium and aluminum alloys have excellent mechanical processing properties such as low density, high specific strength, high specific stiffness, vibration reduction, and electromagnetic shielding. After processing, they can achieve high surface quality, no pollution to the environment, good recyclability, and meet environmental requirements.

A certain watch customer uses other brands of cutting oil, and often experiences problems such as high smoke, strong odor, easy burns, burrs, and fast tool wear during the process of processing fine components. This is related to the performance of the processing oil used, and there are cases of improper product selection.
