How to carry out machine tool spindle maintenance
Maintenance of machine tool spindle is mainly to reduce the working temperature of bearings. Lubricating oil is often used. Lubrication mode, oil - gas lubrication, oil - liquid circulation lubrication two. The following points should be noted when using these two methods:
1, in the use of oil circulation lubrication, to ensure that the spindle constant temperature oil tank is sufficient.
2. Oil and gas lubrication is just the opposite of oil and liquid circulation lubrication. It only needs to fill 10% of the bearing space capacity.
The advantage of circulating lubrication is that, in the case of satisfying lubrication, it can reduce friction heat, and it can absorb a part of the heat of the spindle assembly. For the main shaft lubrication, there are also two types of discharge: oil mist lubrication and injection lubrication.
