How to maintain bearings for CNC grinding machine electric spindle-

Many people will ask what is the maintenance process of the CNC grinding machine electric spindle bearing? 1. When the bearing has operated to a certain stage (or maintenance period), the bearing needs to be removed immediately; 2. Use the diesel engine or gasoline used for cleaning to soak the bearing. If there is a technical standard, it is best to open the dust cover for cleaning; 3. After cleaning, dry the cleaning oil and check the appearance for damage; 4. Use a wooden stick (preferably a hollow tube) with a diameter of about 150mm and the nominal diameter of the angular contact ball bearing, and determine a bearing at one end; 5. Expertise Under the premise of quickly rotating the bearing, put the other end of the wooden stick (wooden tube) behind the ear or on the microphone of the audio amplifier to hear the rotating noise of the bearing; 6. After fixing the bearing, turn the wooden stick horizontally to check whether the bearing is damaged or loose ; 7. Bearings with severe looseness, too much rotating noise, or serious damage should be replaced in time, and replaced with the same type; temperature), put the inspected bearing into the barrel and soak until no air bubbles escape. Remove the bearing before the grease is cooled, and the amount of residual grease is reduced. Remove the angular contact ball bearing after the grease is cold, and there will be a large amount of residual grease. Determine whether there is more or less grease residue according to requirements. 9. Wipe off the lubricating grease on the outside of the bearing with a thin cloth or paper towel, and install the bearing on the roller intact. The daily maintenance work can only be considered complete. Only when the torque is accurate can the rotation be stable!
