S1, in the feeding process, a plurality of workpieces are placed in a feed inlet (23) storage tank, a push rod motor (24) controls a push rod (25) to push the workpieces down from a drop opening (26), one workpiece is conveyed to one end of a grinding guide roller (35) and falls into a push plate groove (21), the position of the workpiece falling between two grinding guide rollers (35) is limited by the inner side of the push plate groove (21), the distance between the two grinding guide rollers (35) is adjusted according to the diameter of the outer circle of the workpiece through a guide roller adjusting mechanism of a bottom plate, the included angle of the cross section of the position where the axis of the workpiece and the two grinding guide rollers (35) abut against each other is 120 degrees, and the bottom surface of a grinding tool removes materials from the outer circle of the workpiece through adjusting a feed mechanism;

s2, in the machining process, the grinding guide rollers (35) rotate in the same direction and at the same speed, so that the workpiece is driven to rotate, the first motor (13) controls the push plate (20) to drive the workpiece to move along the axial direction of the grinding guide rollers (35), and the specific direction is that the workpiece moves from one end of the grinding guide roller (35) close to the feeding hole to one end of the grinding guide roller (35) close to the material collecting box (27); when the rotating and translating workpiece passes through the grinding tool (49), the workpiece is in contact with the grinding tool (49), the bottom surface of the grinding tool (49) removes materials from the excircle of the workpiece, the workpiece is made to reciprocate and move at variable speed through numerical control programming, and when the positions of two sides of the workpiece, which are close to the end surfaces, are in contact with the grinding tool (49), the translation speed of the workpiece is low, so that more materials at two ends of the workpiece are removed; when the middle section of the workpiece is in contact with the grinding tool (49), the translation speed of the workpiece is high, so that the material removal of the middle section of the workpiece is low, and the generatrix of the workpiece is in a convexity shape;

and S3, after the workpiece leaves the grinding tool area, the workpiece keeps rotating and translating, when the workpiece moves to a position beyond the grinding guide roller (35), the workpiece freely falls from between the two grinding rotating shafts (34), the inclined bottom wall of the push plate groove (21) enables the workpiece to freely fall to the side close to the material receiving box (27), the workpiece is received by the material receiving box (27), and then the push plate returns to the initial position and runs in a circulating mode along with the falling of a new workpiece.
