Electric bean grinder tapered cutter split graphic gear and shaft combined with coffee shop special bean grinder

Electric bean grinder cone cutter (cone knife) split diagram, the coffee mill of the original coffee machine looks good, as if it is better than Solis 166, a thousand-yuan electric bean grinder.

The quality of the combination of the gear and the rotating shaft is very good. The bottom of the rotating shaft is deformed with a hammer, but the plastic gear is still not separated! If this gear is made of metal, it is quite difficult to break, it seems that the deliberate use of plastic may have the following reasons: low cost? Is it convenient to sell another one? Protect the motor?
