　　What are the maintenance methods for machine tool spindles? The CNC sponge cutting machine manufacturer states:

　　Now, let’s talk about spindle maintenance. When it comes to machine tool spindle upkeep, the primary goal is to reduce the operating temperature of the bearings—something typically achieved through lubrication. Common lubrication methods include oil-air lubrication and oil-spray circulation systems. When using either of these methods, keep the following points in mind:

　　1. When using oil circulation lubrication, ensure that the main spindle's constant-temperature oil tank has an adequately full oil level.

　　2. The oil-air lubrication method is the exact opposite of oil circulation lubrication—it only requires filling 10 percent of the bearing’s space capacity.

　　The advantage of recirculating lubrication is that, while ensuring adequate lubrication, it can reduce frictional heat and even help absorb some of the heat generated by the spindle assembly. As for spindle lubrication, there are also two common methods: oil mist lubrication and jet lubrication.
