Proper Usage of Anti-Wear Hydraulic Oils:

Firstly, choose the right oil: It is essential to select the appropriate viscosity grade based on the design parameters, operating conditions, and environmental temperatures of the hydraulic system. A viscosity that is too high can increase pressure drop and power loss in the operating system, while an excessively high viscosity may make it difficult to start up during the cold season. A viscosity that is too low can lead to increased internal leakage in the pump, reduced volumetric efficiency, lower system pressure, higher oil temperature, increased wear, and a higher risk of system control failure. Good lubricity is necessary to ensure that critical components of the system are not worn and to minimize failures (especially for anti-wear hydraulic oils, this requirement is even more pronounced). The product should have good compatibility with non-metallic materials such as elastic seals and coatings, preventing metal corrosion, coating dissolution, and excessive expansion of rubber. The product should also exhibit good anti-foaming and air release properties, excellent filterability, and a certain degree of cleanliness. Considering cost-effectiveness, it's not necessary to choose the most expensive option; just the right one.

1. Free from moisture, the use of medium-cooled water or water-based cutting fluids from previous processes, which may mix with cutting oil, can lead to emulsification and corrosion of the cutting oil, reducing its lubricating properties. This results in a decrease in cutting speed and a shorter tool life. Generally, separation, sedimentation, and filtration are employed to promptly remove moisture.

2.除去 chips, a large amount of chips entering the cutting oil can cause oxidation, the formation of sediment, and may also affect cutting accuracy and tool life due to abrasive wear. Filters should be installed in the oil circuit to promptly remove various solid sediments from the filter mesh and the bottom of the oil tank.

Ensure proper sealing to prevent the mixing of lubricating oil with cutting oil, which could damage their respective properties.

4. Due to the variety and distinct characteristics of oil-based cutting fluids, establishing a unified oil change schedule or oil change criteria is unrealistic. Decisions must be made based on the degree of decline in the main performance attributes.
