本文在自行研制的超声振动珩磨装置基础上对高强度钢深孔进行了超声珩磨和普通珩磨的对比试验研究，通过工件内表面粗糙度、表面形貌的分析，得出了超声珩磨明显优于普通珩磨，并提出了超声振动珩磨独特的加工机理。文中还通过实验得出了超声振动珩磨的谐振频率随负载的增大而增加的结论，这与文献［8］的结论有所不同。 Based on the self-developed ultrasonic vibrating honing device, the comparative experiments of ultrasonic honing and ordinary honing of the deep hole of high strength steel were carried out. Through the analysis of the inner surface roughness and the surface morphology of the workpiece, the ultrasonic honing is obviously superior to Ordinary honing, and proposed a unique ultrasonic vibrating honing mechanism. In this paper, we also conclude that the resonant frequency of ultrasonic vibration honing increases with the increase of load, which is different from the conclusion of [8].
