In general machining centers or CNC lathe application scenarios, various types of spindle bearings are used, so how to judge the quality of CNC lathe spindle bearings can be summarized into the following aspects: 1. Is the outer packaging box clear? Generally speaking , Well-known bearing brands have professional design staff to design the outer packaging, and organize production standards to pass the factory to carry out production, so the outer packaging is very clear and unambiguous from the line to the color. 2. Is the anti-counterfeit mark word clear? Well-known brand words, models, etc. are printed on the bearing body. The font style is very clear. The counterfeit text is not only ambiguous, but because the hot stamping process is not smooth, the fonts float on the surface, and some of them can be erased directly. 3. Is there any noise? Hold the inner sleeve of the bearing body with your right hand, turn the outer jacket with your left hand to make it rotate, and listen to whether there is any noise. Because the production standards of some counterfeit materials are outdated, and the operation is completely manual workshop, it is inevitable to mix debris such as gravel in the production process, which is hidden in the bearing body, so it will release debris when it is rotating. ring. This is also the highest among the genuine factory brands that strictly abide by the production standards and use advanced equipment. 4. Is there dirty oil stains on the surface? If there are thick oil stains on the surface of the bearing body, which is thick and sticky when held in the hand, it means that the anti-rust work is relatively simple, and the bearing manufacturers that have done a good job in anti-rust, the surface It is the imprint of the rust inhibitor that cannot be seen. 5. Is the chamfering uniform? The chamfering of the bearing, that is, the intersection of the horizontal plane and the vertical plane, the counterfeit CNC lathe spindle bearings are not handled well in those well-ordered positions due to the production of professional skills. As you wish. Only when the torque is accurate can the rotation be stable.
