PA plastic hollow pepper ball is oil resistant, high temperature resistant, good toughness and strong impact resistance, which is widely used in automobile parts, mechanical equipment and other fields. However, PA plastic hollow pepper ball is used as a sealing ball, which requires high precision and surface smoothness.

The accuracy of PA plastic hollow pepper ball is mainly related to the post-processing technology. Because PA plastic has the characteristics of water absorption, if PA plastic hollow pepper ball is washed with water or water-containing liquid during the processing, the accuracy of the processed PA plastic hollow pepper ball will definitely be low, because the volume of PA plastic will expand after water absorption and will shrink after drying. Therefore, the cleaning lubricant used for grinding PA plastic hollow pepper ball with a ball grinder is a non-moisture grinding liquid, and only the non-moisture grinding liquid is used.
