Drilling and tapping cnc machine center bearing causes

Nov 18, 2019

Drilling and tapping cnc machine center's spindle is parallel to the work center. The workbench is a square indexing turntable or CNC turntable. It is suitable for machining the workpieces of the box type. It is possible to machine complex types of workpieces. Common horizontal machining centers are three linear motion coordinates plus one rotary motion coordinate (rotary table). ALLES CNC today mainly introduces the advantages and disadvantages of machining centers.

Drilling and tapping cnc machine center structure advantages


Drilling and tapping cnc machine center Compared with CNC vertical machine center, CNC horizontal machine center is easier to chip the workpiece during machining. It is more advantageous for complex undercut and mold cavity machining. Due to the structural advantages of CNC horizontal machine center, CNC horizontal machine center can process large workpieces. Simply put, workpieces that are difficult or impossible to machine in CNC vertical machine center can be machined on horizontal machining centers.


Drilling and tapping cnc machine center structure shortcomings


The disadvantages of CNC horizontal machine center are that it has a large area, its structure is complicated, the price is more expensive than the CNC vertical 3 axis machine center, it is inconvenient when debugging the CNC horizontal machine center program, and the tool movement track is not suitable during machining. Observing, the loading and unloading of the workpiece is not convenient, and the processed workpiece is not easy to measure;


In summary, from the advantages of the CNC vertical machine center, it can be seen that the CNC horizontal machine center is more suitable for processing the workpiece of the box type, and can process the peripheral surface of the box type workpiece. In the program debugging, tool path observation, workpiece loading and unloading, workpiece measurement has many inconveniences.


Drilling and tapping cnc machine center bearing causes


First, improper installation


1. Use brute force during installation, directly hit the bearing with a hammer to damage 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.


Third, pollution


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: Drilling and tapping cnc machine center Do not disassemble the bearing before use; keep the installation environment clean during installation, clean the bearings to be used; and strengthen the bearing seals.


Fourth, fatigue


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.
