Friction is an insurmountable phenomenon. All machine parts will inevitably rub against other parts or materials during use. If there is friction, there will be wear, just because the material and processing technology of the parts are different, and the degree of wear is different.
The blade of soybean milk machine also involves the above problems of material selection, processing, manufacturing and use, so it will also wear.
The blade of Jiuyang soymilk machine will wear like other soymilk machine blades, but the speed of wear is different at most.
