However, with the continuous updating of the engineering field, the occurrence of multiple extreme working conditions such as overload, high-frequency vibration, ultra-long service life, large temperature difference fluctuation, strong corrosion and the like provides higher performance requirements for the characteristics of the lubricating oil. On one hand, a new formula can be tested again to meet the working condition requirement of the lubricating grease, and on the other hand, the existing lubricating grease can be used for quenching and tempering to meet the new working condition requirement. It is important that sufficient testing and validation be required before the final formulation and various production parameters can be determined.
