The cause of defects that appear on the surface of bearing after grinding is frequently encountered in the process of bearing production. In this regard, it is necessary to carry out further exploration and subtle judgment. This article will analyze the causes of bearing surface defects caused by grinding in detail, so as to help people better control the grinding quality of bearings.
The most common causes of surface defects in bearings are grinding process parameters, grinding tool wear and poor grinding technique.
First of all, the grinding process parameters are the most common cause of bearing surface defects. In the process of grinding bearing surface, if the grinding process parameters are wrong due to some reasons, the machining accuracy and the surface quality of the machined will be affected a lot. At the same time, it will also cause defects on the bearing surface, such as scum, burrs, etc. If the grinding parameters are wrong, it should be adjusted in time.
Second, grinding tool wear is also the cause of grinding defects in bearings. With the prolongation of grinding time, the grinding abrasive particles gradually lose their sharpcutting edges, or even fall off or break, resulting in insufficient cutting depth or broken ends on the surface of the bearing. It not only affects the surface quality of the bearing, but also causes the bearing to generate surface defects. Therefore, tool wear should also be monitored in time to ensure that the grinding effect is good.
Third, it appears that poor grinding technique will also cause defects on the bearing surface. Generally, in the process of grinding bearing surface, if too large force or too small force is applied, it will lead to the insufficient bearing surface grinding depth or depth unevenness, which may make the bearing surface appear Surface defects, such as rough surface, grinding burns and the like. Therefore, in the process of grinding bearing surface, it is necessary to operate correctly, so as to reduce the generation of defective products to the greatest extent.
These are the three main reasons for the bearing surface defects caused by the grinding process. It is necessary to correct and improve the grinding process in time to reduce the number of bearing surface defects.
