Machine tool spindle bearing lubrication purposes:
Machine tool spindle bearing lubrication to reduce internal friction and spindle bearings wear to prevent burning stick, its lubricating effect is as follows.
⑴. Reduce friction and wear.
Constituting the spindle bearing rings, rolling elements and the mutual contact portion of the retainer to prevent the metal contacts, reducing friction and wear.
⑵. Extend the fatigue life.
Machine tool spindle bearings rolling fatigue life, in the rotation, the rolling contact surfaces oiled, then extended. Conversely, low viscosity oil, the lubricant film thickness is not good, is shortened.
⑶. Discharge frictional heat, cooling
Circulation to the oil law and other oil discharge occurred by friction heat, or heat coming from the external cooling. Machine tool spindle bearings prevent overheating and to prevent lubricant itself aging.
⑷. Others
Also prevent dust and debris inside the bearing spindle, or to prevent rust, corrosion effect.
Lubrication method:
Machine tool spindle bearing lubrication methods, divided into grease and oil lubrication. In order to play well bearing spindle function, first, to select the appropriate conditions of use, purpose of use lubrication method. Only consider lubrication, oil lubrication dominant. However, there can be simplified greased machine tool spindle bearings around the structure of expertise, will grease and oil lubrication compare the pros and cons.
