Because of the harm of all kinds of essential and external factors, the specification of the outside needle of the stamping die will be corroded. Therefore, before adopting the anti rust treatment, we should fully grasp the actual causes of the problems. Then we can choose reasonable solutions purposefully.

The size of the needle bearing on the outside of the stamping die is etched by its own raw materials, because it is made of 45 steel, so its composition and structure will be diazotized into embroidery. Naturally, it is also related to the surface smoothness of the cylindrical roller bearing on the outside of the stamping die. Generally, the charging battery with oxygen concentration difference is corroded.

In addition, the composition and pH value of aqueous solution in contact with the surface of cylindrical roller bearing on the outside of the stamping die; the working temperature and environmental humidity of the storage rolling bearing; various natural environmental substances in contact with the surface of the rolling bearing are all immediately harmful to the corrosion resistance of the cylindrical roller bearing on the outside of the stamping die.

In order to provide antirust treatment for the cylindrical roller bearing on the outside of the stamping die, first of all, pay attention to the surface cleaning of the rolling bearing. The cleaning must be carried out in accordance with the characteristics of the surface of the antirust treatment and the standards at that time, and select the appropriate way. Generally, there are many cleaning methods such as organic solvent cleaning, organic chemical solution cleaning and mechanical equipment cleaning.
