This paper presents an alternative centerless grinding machine technology, that is, through feed surface grinder centerless grinder. In the new method, a compact centerless grinder units, guides, ultrasonic crawler, a blade of their respective holders, mounted in a surface grinder table at the workpiece is fed into and through feed centerless grinding machine operation is performed guides the space between the grinding wheel and the ultrasonic crawler. Ultrasonic crawler, the metal elastic body is bonded to the piezoelectric ceramic production, inclined at a small angle in order to provide sufficient strength to control the rotational movement of the workpiece, and feed the ultrasonic elliptical vibration of the workpiece along its axis. In this article, the movement of the workpiece control we must first ensure that the workpiece speed and feed rate can completely control the ultrasonic crawler, which is a high-precision grinding operation is essential. Then, the main process parameters, such as the eccentric angle of the workpiece, the cutting, the ultrasonic crawler inclination angle of the machining accuracy of the applied voltage amplitude (i.e., the roundness of the cylindrical workpiece and the workpiece) were clarified experiment. The results obtained show that: (1) the workpiece rotational speed can be adjusted by changing the amplitude of the applied voltage, by feedrate can be changed by applying a voltage magnitude and the ultrasonic crawler inclination angle of adjustment; (2) the top of the eccentric angle of 6 , a larger cutting a smaller inclination angle, or the higher the applied voltage is better for higher machining accuracy; (3) and roundness of cylindrical workpiece from the initial value 16.63m 14.86m improvement Finally, the optimum grinding conditions under 1.49 microns and 0.74 microns.Keywords: centerless grinding surface grinding machine ultrasonic vibration track runs through the feed roundness 1 Introduction Centerles
