- Determination of oil supply and period: The spindle motor must achieve high-speed operation, and it is a very important target to supply the proper oil quantity to the bearing. The oil consumption of the bearing oil and gas lubrication is calculated according to the bearing scale parameters. The reasonable lubrication period of high-speed bearings is 3-10min/time. For details, please refer to the bearing supplier’s recommended value (such as ➡︎4.5KW ATC Air Cooled Spindle Automatic Tool Change Spindle ISO30 220V 380V for CNC Router⬅︎).
- Routine maintenance: When using the oil and gas lubrication system, it is necessary to prohibit the leakage of oil and gas discharge pipelines. If there is leakage, the transportation of lubricating oil will cause problems. Therefore, in the operation of the oil and gas lubrication system, it is necessary to always check the pipeline condition and the oil flow situation. We also need to pay attention to the back lubrication of the spindle lubrication passage and the cavity. When the back pressure is too high, it will affect the speed of oil and gas transportation. When the back pressure is equal to the oil pressure, the oil and gas will not move, which will cause the lubricating oil to reach the bearing. position. Therefore, it is necessary to pay attention to the outstanding oil flow in daily inspections. The selected oil and gas lubrication equipment should have the oil and gas pressure detection and alarm function so that the hidden danger alarm is declared when the back pressure of the bearing cavity rises, the pipeline leaks and the pipeline is blocked, and the high-speed operation of the ATC spindle motor is ensured.
- Compressed air quality: In addition to the above-mentioned oil supply and fuel supply cycle, the quality of compressed air is a key factor in the high-speed operation of the electric spindle. Compressed air is not only the power to transport the lubricant, but also affects the operating life of the bearing. Dust impurities in compressed air, moisture, etc. are factors that seriously threaten bearing life. Therefore, it is essential to equip the electro-spindle oil and gas smoothing equipment with high-precision air source filtration and drying system.

Oil and gas lubrication is a lubrication method for high-speed operation of spindle motors. This method not only ensures long-term lubrication of bearings but also suppresses the temperature rise of bearings. When using oil and gas lubrication, we should pay attention to the following issues to avoid equipment alarms:
