Abstract


Engineering ceramic materials have excellent physical and chemical properties , making it an attractive prospect in some special areas such as high temperatures , corrosion and wear , and other places , but it is due to the excellent performance , making its processing also brought difficult. Generally use special processing methods such as ultrasonic grinding composite processing . The composition of the application and its domestic and international overview of ultrasonic machining and ceramic ultrasonic grinding equipment engineering ceramics , craft requirements are introduced in detail . And the the ultrasonic grinding mechanism analysis . In ultrasonic machining processes , the related electrical control systems play a very important role in the performance parameters of good or bad , will directly affect the processing effect or even safe operation of equipment , particularly important for the design and development of related equipment and optional . In this paper, some important electrical control equipment such as ultrasonic power , AC inverter motor , inverter and attachment structure principle, performance parameters analyzed introduced . At the same time , in order to achieve constant speed grinding of ceramics , in order to achieve better processing , computer AC inverter motor drive grinding spindle with a digital closed-loop control , the paper on the basis of the mathematical model are analyzed and discussed . Ultrasonic grinding addition, the introduction of the concept of elastic energy , combined with fracture model to explain the subject experiments Al 2 O 3 engineering ceramic ultrasonic and mechanical grinding The comparative results .
