振动切削技术具有优良的工艺效果,但在加工实践中却难以推广应用,其重要原因之一是系统较复杂,效率低下。通常采用大功率的电子管式超声波激振源,体积大而笨重。本文以振动车削为例,从超声波振车削中切削能量出发,定量研究了完成振动切削所需的刀具超声振动功率。据此提出了采用高效的压电换能器,以及直接驱动刀具的新型超声振动切削系统,并对系统特性进行了测试。 Vibration cutting technology has excellent technological effects, but it is difficult to promote the application of processing practice, one of the important reasons for the system is more complex and inefficient. Usually using high-power ultrasonic tube excitation source, bulky and bulky. In this paper, the vibration turning, for example, starting from the cutting energy of ultrasonic vibration, quantitative study of the tool to complete the vibration cutting ultrasonic vibration power. Based on this, a new type of ultrasonic vibration cutting system that uses efficient piezoelectric transducers and drives the tool directly is proposed. The system characteristics are also tested.
