How to check the bearings of a metal laser cutting machine

For the laser cutting machine, the bearing is a very important part. Metal laser cutting machine belongs to a type of laser cutting machine, so the bearing is equally important to it. Once the bearing has a problem, it will affect the normal operation of the metal laser cutting machine, so the bearing of the metal laser cutting machine should be checked frequently. So how should the bearing of the metal laser cutting machine be checked? 　　 First of all, we need to see whether the steel printing of the metal 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.　　 Secondly, observe whether the metal laser cutting machine has any noise: hold the inner sleeve of the bearing with the left hand, rotate the outer sleeve with the 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 the biggest difference from a genuine brand that strictly enforces production standards and operates with machines.　　 Next, check 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. The last step is to see if the chamfer of the metal laser cutting machine is uniform: the so-called chamfer of the bearing, that is, the intersection of the horizontal and vertical planes, counterfeit bearings cannot be handled at these corners due to the limitation of production technology. Satisfactory.　　 Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment.
