The factor related to lubrication that affects the accuracy of the operation of the electric spindle is the heat generated by the electric spindle. The internal heat source of the electric spindle comes from two aspects: 1. The heat of the spindle bearing; 2. The heat generated by the built-in motor of the electric spindle.
Solving the heating of the motor requires cooling the stator of the motor. It can be realized by circulating water cooling method to take away the heat of the motor. To solve the heating problem of the spindle bearing, it is necessary to take away the heat generated by the bearing operation in time. The traditional thin oil lubrication is to transport a large amount of lubricating oil to achieve invasive lubrication, and at the same time, the lubricating oil takes away the heat. There are disadvantages in such a lubrication method. One is to waste a large amount of lubricating oil, and the other is that the lubricating oil is rubbed between the lubricating oil molecules and the pipe to generate a large amount of circulating heat during the circulation, resulting in an increase in oil temperature. Not only can not play a good cooling effect, but also lead to an increase in bearing temperature, which is not conducive to the performance of the spindle bearing. Therefore, eliminating the generation of frictional heat between molecules inside the liquid becomes the key to solving the problem. Practice has shown that oil and gas lubrication can fundamentally avoid this situation. First, oil and gas lubrication provides a small amount of lubricant to meet the amount of lubricant required for the bearing. Secondly, the oil and gas lubrication does not cause the friction of the lubricating oil molecules to generate heat, and the clean compressed air takes away the heat generated by the bearing, keeping the spindle running at a stable temperature. This can effectively solve the problem of thermal deformation caused by an increase in temperature.

Analysis of Factors Affecting Performance of Electric Spindle
High operating speed is one of the characteristics of the electric spindle. Good lubrication of the bearing is an important indicator to ensure its normal operation. Therefore, it is important to equip the suitable electric spindle lubrication system.
