[0002] In the current technology for manufacturing carbon brushes, it is often necessary to press the mixed slurry into a mold and dry the carbon brush in the mold. Then, the dried carbon brush block is cut and ground to ensure that the carbon brush block is formed into a suitable size and shape and that the surface remains flat. In addition, in order to adapt to the shape of the shaft and ensure good performance, the carbon brush sometimes needs to be sawn with a small notch.

[0003] However, if the carbon brush is ground to create a notch after sintering, it is not only easy for the carbon brush to crack during the process, but also the grinding of each carbon brush individually is inefficient. Utility Model Content
