Description
Technical Field

[0002] With the booming economy, cars have become widely popular around the world, and almost every family can own one. However, each car is carefully assembled from many large and small parts. Given that the assembly quality of a car is directly related to the life safety of the user, the fine grinding of auto parts during the production process is particularly important. In particular, key parts such as connecting shafts and transmissions often have tiny burrs on the edges during the production process. If these burrs are not handled, they will cause wear to the parts in contact with them, thereby affecting the overall performance and service life of the car.
[0003] Traditional burr grinding methods are often limited to single-sided grinding of automotive parts, and then rely on manpower for multi-directional fine grinding. This process is time-consuming, labor-intensive, and inefficient. More importantly, because burrs are small and difficult to detect, grinders often tend to neglect their thorough cleaning, which to a certain extent causes a waste of resources. Therefore, seeking a more efficient and accurate burr grinding and cleaning method has become an important issue that needs to be urgently addressed in the automotive industry. For the above-mentioned problems, there may already be technical means to solve them in the prior art, but this case intends to provide an alternative or replacement technical solution.
