CNC machine bearings common quality problems and main causes.

2,221 Published by Nov 30,2018

When assembling cnc machine bearings, the Venus machine tool must be preloaded, so that the original clearance will be eliminated after the cnc machine bearings are installed. That is to say, the contact angle and accuracy of the cnc machine bearings have a very important role. Therefore, when installing the bearing, it is necessary to ensure that the contact angle is qualified and the actual width of the angular contact ball bearing must be in compliance with the regulations. It is not uncommon for a bearing to malfunction during operation, so there is no need to make a fuss. A fault has occurred and it is critical to judge and handle it.

Below we analyze the common quality problems and causes of cnc machine bearings.
1. improper installation of cnc machine bearings
1. Use brute force during installation. Directly hitting the bearing with a hammer will cause the greatest damage to the cnc machine bearings; it is the main cause of deformation. This is very common in small machine tool plants, and the Venus machine uses a professional cnc machine bearings to install the bearings, thus avoiding this.

2, the installation is not in place, the installation is biased or not loaded to the bearing position, causing the cnc machine bearings clearance is too small. The inner and outer rings are not in the same center of rotation, causing disagreement.
Recommendation: Select an appropriate or professional bearing installation tool, and use a special instrument to detect it after installation.
Second, the poor lubrication of cnc machine bearings
According to the investigation, poor lubrication is one of the main causes of premature failure of cnc machine bearings. The main reasons include: not adding lubricant or lubricating oil in time; lubricant or lubricating oil is not filled in place; improper selection of lubricant or lubricating oil; incorrect lubrication method, etc.
Recommendation: Choose the right lubricant or lubricant and use the correct lubrication method. 
3.cnc machine bearings pollution
Contamination can also cause premature damage to cnc machine bearings. Contamination means that dust, metal chips, etc. enter the interior of the cnc machine bearings. The main reasons include: opening the bearing packaging too early before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the bearing is not clean, and the working medium is polluted. All the spindle assembly of the Venus machine is completed in a constant temperature clean room, thus avoiding the pollution of cnc machine bearings.
Recommendation: It is best not to disassemble the packaging of cnc machine bearings before use; keep the installation environment clean during installation, clean the bearings to be used; and strengthen the sealing device of the bearings.

4.cnc machine bearings fatigue
Fatigue damage is a common way of damage to cnc machine bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to repair in time; improper maintenance; equipment aging.
5.the quality of cnc machine bearings
The quality of cnc machine bearings is directly related to the service life. All of our factories use imported bearings or domestic first-line brands to avoid this problem.
