Centerless Grinding machines is a type of grinder that does not require the use of the axis of the workpiece for grinding. It generally consists of a grinding wheel, a guide wheel, and a bed. The grinding wheel and guide wheel are installed on the bed, and the grinding wheel actually performs the grinding work. The guide wheel is equipped with a linear guide rail perpendicular to the axis, which controls the diameter of the workpiece through the movement of the linear guide rail. When it is necessary to adjust the shape of the grinding wheel and guide wheel, two sets of cross shaped guide rails need to be set up to drive the adjusters to adjust the grinding wheel and guide wheel separately. Due to the large number of guide rails, the entire system is very complex and it is difficult to achieve high adjustment accuracy. Including grinding wheel 1, guide wheel 6, and bed body 9, grinding wheel 1 and guide wheel 6 are respectively installed on bed body 9 by grinding wheel frame 2 and guide wheel frame 7, and guide wheel frame linear guide rail 8 is installed under guide wheel 6. Its feature is that a grinding wheel frame guide rail 3 is set between grinding wheel 1 and bed body 9, which is perpendicular to the guide wheel frame linear guide rail 8, and guide wheel conditioners 4 and 5 are respectively installed on the side of grinding wheel frame 2 and guide wheel frame 7. The two mutually perpendicular guide rail CNC systems can be driven by two conditioners to respectively adjust grinding wheel 1 and guide wheel 6. After the adjustment is completed, the guide wheel frame linear guide rail 8 under guide wheel 6 is controlled by the CNC system to adjust the size of the workpiece. Due to the use of two adjusters to respectively adjust the grinding wheel and guide wheel, the guide wheel adjuster is installed on the grinding wheel frame and driven by the movement of the grinding wheel frame guide rail,
