Inspection of bearing quality of metal laser cutting machine

Whether the chamfer of the metal laser cutting machine is uniform: the so-called chamfer of the bearing is the junction of the horizontal and vertical planes. Due to the limitation of production technology, the counterfeit bearings are not handled satisfactorily at these corners and corners. Whether the steel printing of the metal laser cutting machine is clear: Brand words, labels, etc. will be printed on the bearing body. The fonts of counterfeit products are not only blurred. Due to the rough printing technology, the fonts float on the surface, and some of them can even be easily erased by hand. The fonts are very small, but most of the products produced by the factory use steel stamping technology, and they are pressed before heat treatment. Therefore, although the fonts are small, they are deeply concave and very clear. Due to the backward production conditions of most counterfeit products and the completely hand-crafted workshop operation, it is inevitable that impurities such as sand will be mixed in the bearing body during the production process, so noise will be generated when rotating.  Is there any noise in the metal laser cutting machine: Hold the inner sleeve of the bearing with your left hand, and rotate the outer sleeve with your right hand, and listen to whether there is any noise. This is the biggest difference from a genuine brand that strictly enforces production standards and operates with machines.   Whether there are turbid oil stains on the surface: This should be paid special attention to when purchasing imported bearings. The above are some methods for testing the bearing quality of metal laser cutting machine. If you have encountered it, you can check it out.
