The machine is made of steel and the head of the grinding disc is cast iron. It will rust when exposed to water. After use please remember to wipe it dry and store it. Frequently wipe some cooking oil for anti-rust maintenance. Pay attention to the powder produced during the first use there will be some rust in the middle which is a normal phenomenon and it will be fine after several trials. And the red fan cover of the machine may be bumped and dented during transportation but this does not affect the use.
