由于原材料的低成本和与之相关的吸引人的性能，陶瓷在制造用于工程应用的若干部件方面得到了广泛的应用。该陶瓷研究了旋转超声磨削在计算机硬盘陶瓷基板（钙铝石）磨削中的应用。与现有的加工方法相比，该工艺具有更强的加工强度。

CERAMICS ARE FINDING WIDESPREAD APPLICATION IN THE FABRICATION OF SEVERAL COMPONENTS FOR ENGINEERING APPLICATIONS, BECAUSE OF THE LOW COST OF THE RAW MATERIAL AND THE ATTRACTIVE PROPERTIES ASSOCIATED WITH THEM. THIS CERAMIC INVESTIGATES THE APPLICATION OF ROTARY ULTRASONIC GRINDING FOR GRINDING OF CERAMIC SUBSTRATES (CANASITE) FOR COMPUTER HARD DISKS. THIS PROCESS EXHIBITS INCREASED MACHINING AGGRESSIVENESS COMPARED TO THE EXISTING MACHINING METHODS EMPLOYED.
