Grinding media
The glass beads made of sodium-calcium glass have good chemical stability, certain mechanical strength and hardness. Therefore, grinding materials have the following advantages over other grinding materials:
(1) longer service time than any other medium except metal abrasive materials.
(2) not contaminating the processed metal.
(3) to restore the original cleanness and smoothness of the processed materials.
(4) can speed up the cleaning, while maintaining the processing accuracy of the original objects.
