First, improper installation
1. Use brute force during installation. Directly tapping the bearing with a hammer will cause the greatest damage to the bearing; it is the main cause of deformation.
2, the installation is not in place, the installation is biased or not installed to the bearing position, resulting in too small bearing clearance. The inner and outer rings are not at 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, poor lubrication
According to the survey, poor lubrication is one of the main causes of premature bearing damage. 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.
Contamination can also lead to premature bearing damage, which means that dust, metal chips, etc. enter the bearing. 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.
Recommendation: It is best not to disassemble the bearing before use; keep the installation environment clean during installation, clean the bearing to be used; and strengthen the bearing seal.
Fatigue damage is a common way of damage to bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to repair in time; improper maintenance; equipment aging.
Recommendation: Select the appropriate bearing type and replace the fatigue bearing regularly.
Horizontal machining centers and horizontal five-axis machining centers have rarely been introduced since the establishment of the station, because horizontal machining centers are relatively few in the market, and users purchase small horizontal machining centers. There are many users who generally choose vertical machining centers. . The reason is that the vertical machining center has a small footprint and high cost performance; while the horizontal machining center has a large area and the price is more expensive than the vertical machining center, so the average user rarely chooses the horizontal machining center. Although there are few users in the horizontal machining center, the structure of the horizontal machining center should be introduced to let you know more about the machining center. Xiaobian today introduces the type of horizontal five-axis machining center. The horizontal five-axis machining center can be divided into two types according to the setting of the rotary axis. The two rotary axes are set on the table and the two rotary axes are respectively Set on the spindle and table.
