For the laser cutting machine, whether it can guarantee its normal operation, the bearing plays a very important role. Many times, because of bearing problems, you will know that the laser cutting machine cannot work. Then how to check whether the bearing of the laser cutting machine is normal? Wuhan High Energy Laser will share with you a relatively simple inspection method.  How to check the bearings of a laser cutting machine? There are four simple methods commonly used:   1. Whether the steel printing of the laser cutting machine is clear: The bearing body will be printed with brand words, labels, etc. The font is very small, but most of the products produced by the factory use stencil printing technology, and the characters are pressed before heat treatment. Therefore, although the font is small, it is deep concave and very clear. 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.  2. Is there any noise in the 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. 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 production process and hidden in the bearing body, so noises will be generated when rotating. This is a big difference from a genuine brand that strictly enforces production standards and uses machines to operate.   3. Whether there are turbid oil stains on the surface: This should be paid special attention to when purchasing imported bearings. Since the current domestic anti-rust technology is not very popular, it is easy to leave thick oil stains when anti-rust treatment is performed on the bearing body, which is sticky and sticky in the hand, while it is almost invisible on the original imported bearings from abroad. When it comes to the traces of anti-rust oil, a very careful expert said that the imported bearings smelled a kind of smell, it must be the anti-rust oil, but they can't see it.  4. Is the chamfer of the laser cutting machine uniform: the so-called chamfer of the bearing, that is, the intersection of the horizontal and vertical planes, counterfeit bearings are not handled satisfactorily at these corners due to the limitation of production technology.  Through the above introduction, we can know whether there are any problems with the bearings of the laser cutting machine. When buying the bearings, we can also know the quality of the bearings we buy, so as to avoid being deceived!
