The application market of PMMA plastic pepper ball is divided into decorative plastic pepper ball and optical plastic pepper ball. Because of different uses, the processing technology is also very different. In addition to high diameter accuracy, PMMA plastic pepper ball for optical use also needs good surface smoothness to reach the mirror level. Therefore, the polishing technology of PMMA plastic pepper ball should be polished by special polishing equipment.

The polishing method of ordinary plastic balls can be completed by using a drum polisher, and ordinary polishing abrasives can be added to the drum polisher, while the polishing of PMMA plastic pepper balls needs to be done by using an eddy current polisher, which can check the polishing effect of PMMA plastic balls at any time during the polishing process. Moreover, the eddy current polisher is equipped with a speed regulation function, and the speed can be adjusted according to the actual effect and the number of PMMA plastic balls to be polished, so as to ensure the best polishing effect of PMMA plastic pepper balls.
