Analysis of Ultrasonic Vibration Belt Grinding Processing Method

The sand belt abrasive distribution is relatively uniform, the grinding property is good, it is not easy to burn the workpiece. The sand belt grinding process has great flexibility and adaptability, it can be used for grinding of inner and outer circles, plane and complex curved surfaces. Compared with the closed belt, the open belt is continuously feed slowly. During the grinding process, new abrasive grain continuously enters into the grinding area. The surface quality is good, and one workpiece can be processed in one installation, reducing the assembly error caused by replacing the belt and shortening the processing time.For ultrasonic assisted machining technology, the two-dimensional ultrasonic assisted grinding have better processing results in reducing the grinding heat, the wear of the abrasive tool and the grinding force. By referring to the above processing techniques, this paper proposes a two-dimensional ultrasonic vibration open belt grinding processing method.
