There are several reasons for the wear of mechanical brushes

It is pointed out that the processing efficiency of the brush on the entry surface is higher than that of the brush on the exit surface, and the brush wear is studied from the perspective of brush medium

The influence of working temperature and humidity on the wear rate of the brush is analyzed. Through the formula d = wl3 / 0.1357ed4n, it is pointed out that the larger the diameter of the brush wire is, the higher the hardness is, the greater the wear rate is, and the longer the brush wire is, the lower the hardness will be,

At the same time, it is pointed out that the harder the brush wire is, the faster the wear is under the same material, except for the hardness of the brush wire; With the increase of temperature, the wear rate increases, the humidity increases and the wear rate decreases. Under normal environment, if the temperature increases and the humidity increases at the same time, the effects caused by these two changes can offset each other;

Through long-term observation and comparison of the processing efficiency of the two types of equipment, it is pointed out that the transverse roller brush is suitable for the passivation treatment of the cutting edge of the cemented carbide car blade, while the longitudinal disc brush is suitable for the surface polishing treatment of the cemented carbide blade.
