N2 - Rotary ultrasonic grinding (RUG) is an effective machining method for hard-brittle materials. However, the harsh resonant conditions and wide grinding layer result in small vibration output, large energy loss and high temperature rise for large grinding wheel vibration. Therefore, a contactless transfer type of RUG for large-size, wide-thick grinding layer was developed, where the vibration direction is parallel to the machined surface for the end grinding. Firstly, the non-destructive acoustic wave method was applied to measure the elastic modulus. The simulation calculation were combined to obtain the modal shape and the vibration trajectory. Finally, the result show that the resonant frequency was 21.82kHz. The horizontal vibration output was 7 μm. The temperature rise was 41.7℃ under 5μm vibration for 1h, It was verified the performance of ultrasonic end grinding with high vibration, horizontal vibration and low temperature rise, which is of great significance to industrial production and grinding exploration.
