When pepper balls are manufactured by pepper ball manufacturers, because the size specification of plastic balls is too small, the special pepper ball milling machine used for processing requires higher accuracy, and the polishing machine should also have good sealing performance. Because the size of pepper balls is small, how to seal the polishing machine is not good, then the balls in the machine may leak out along the pores, causing defects and waste.The grinding machine of pepper balls should use special grinding disc and grinding wheel, and the grinding wheel should use special grinding wheel for grinding plastic balls, and the grinding wheel should use fine grinding wheel, so as to fully ensure that the processed pepper balls have enough accuracy. In addition, the polishing of pepper balls should use special turbine polishing machine, and the abrasive should use high-grade zircon polishing balls to polish. Only when the machines and materials are selected correctly can we process high-gloss and high-precision plastic ball products.
