II. Working Principle of the Lubrication System of Vertical Machining Centers
The lubrication system of a vertical machining center is essentially a complex and precise system. It ingeniously utilizes the flow of compressed air within the pipeline to drive the lubricating oil to flow continuously along the inner wall of the pipeline. During this process, the oil and gas are fully mixed and precisely delivered to the spindle section, lead screw, and other key parts of the machining center that require lubrication.
For example, during the rotation of the spindle, the lubricating oil and gas can be evenly distributed on the surface of the bearing, forming a thin oil film, thereby reducing friction and wear, lowering heat generation, and ensuring the high-speed and high-precision operation of the spindle.

(B) Differences
Lubrication methods and effects
Oil-gas lubrication: Oil-gas lubrication precisely injects a small amount of lubricating oil onto the lubrication points. The formed oil film is relatively uniform and thin, which can effectively reduce the consumption of lubricating oil and avoid the pollution caused by excessive lubricating oil to the equipment.
Oil-mist lubrication: Oil-mist lubrication atomizes the lubricating oil into tiny particles and delivers them to the lubrication points through the air. However, this method may result in some lubricating oil failing to accurately reach the lubrication points, causing certain waste, and the oil mist may diffuse into the surrounding environment, causing pollution to the environment.

IV. Detail Points of the Lubrication System of Vertical Machining Centers
(A) Selection of Lubricating Oil
In the market, there are numerous types of lubricating oils with varying qualities. To ensure the lubrication effect of the vertical machining center and the normal operation of the equipment, we must choose lubricating oils with less impurities and high purity. High-quality lubricating oils can provide stable lubrication performance during the equipment’s operation, reduce friction and wear, and lower the incidence of equipment failures.
For example, for high-speed rotating spindles, lubricating oils with good anti-wear performance and high-temperature stability should be selected; for components such as lead screws, lubricating oils with good adhesion and anti-corrosion properties are required.

(B) Regular Cleaning of Filters
After the machine tool has been used for a period of time, a certain amount of impurities and dirt will accumulate inside the filter. If not cleaned in time, the filter may become clogged, resulting in an increase in oil pressure. Under the strong oil pressure, the filter screen may rupture and fail, allowing unfiltered impurities to enter the lubrication system and cause damage to the equipment.
Therefore, regular cleaning of filters is an important link in maintaining the lubrication system of vertical machining centers. It is generally recommended to formulate a reasonable filter cleaning plan based on the usage frequency and working environment of the equipment, usually conducting a cleaning every certain period of time (such as 3 – 6 months).

(C) Monitoring and Maintenance of the Lubrication System
To ensure the normal operation of the lubrication system, real-time monitoring and regular maintenance are necessary. In terms of monitoring, sensors can be installed to detect parameters such as the flow rate, pressure, and temperature of the lubricating oil. If any abnormal parameters are found, the system should be able to promptly send out alarm signals, prompting the operators to conduct inspections and repairs.
Maintenance work includes regularly checking whether there are leaks in the lubrication pipeline, whether the joints are loose, whether the oil pump is working properly, etc. At the same time, the oil storage tank of the lubrication system also needs to be regularly cleaned to prevent the mixing of impurities and moisture.
