Small CNC lathe bearing common problem processing method
I. Improper installation of small CNC lathes
1. When a small CNC lathe is installed, brute force is used. Directly hitting the bearing with a hammer has the greatest damage to the bearing; it is the main cause of deformation. This is very common in some small machine tool factories. Venus uses a professional bearing installation tool to install bearings, thus avoiding this.
2. Small CNC lathes are not installed properly, and the installation is biased or not mounted on the bearing, causing the bearing clearance to be too small. The inner and outer rings are not in the same center of rotation, causing distractions.
Recommendation: Select the appropriate or professional bearing installation tool and use a special instrument for inspection after installation.
Second, poor lubrication
According to investigations, poor lubrication is one of the major causes of premature bearing damage. The main reasons include: the lubricant or lubricant is not added in time; the lubricant or lubricant is not filled in place; the lubricant or lubricant is improperly selected; the lubrication method is not correct.
Recommendation: Select the right lubricant or lubricant and use the correct lubrication method.
Third, pollution
Contamination can also lead to premature bearing damage. Contamination refers to dust, metal chips, etc. entering the bearing interior. The main reasons include: prematurely opening the bearing package before use, causing pollution; the working environment is not clean when installed, causing pollution; the working environment of the bearing is not clean, and the working medium is contaminated. All spindle assembly of Venus Machine Tool is completed in a constant temperature clean room, thus avoiding bearing contamination.
Recommendation: It is best not to disassemble the bearing package before use; to keep the installation environment clean during installation, to clean the bearings to be used; to strengthen the bearing sealing device.
Fourth, fatigue
Fatigue damage is a common way of bearing damage. Common causes of fatigue failure may be: long-term overload bearing operation; not timely maintenance; improper maintenance; equipment aging.
