The Morse taper handle 4 plays the role of assisting in fixing the rod end joint bearing. Then, the staff holds the long rod part of the rod end joint bearing with one hand and presses the Morse taper handle 4 down with the other hand to rotate it. The Morse taper handle 4 drives the steel ball 5 to circulate and roll in the inner ring arc groove of the rod end joint bearing, thereby polishing the inner ring arc groove of the rod end joint bearing smoothly, solving the problem that the inner ring arc groove of the rod end joint bearing is subjected to inconsistent force during manual polishing, resulting in low and uneven polishing smoothness, and the problem that the smoothness of each part cannot be polished the same, thereby improving the qualified rate of the finished product, avoiding the situation of causing a lot of rework, thereby reducing the labor intensity of the staff and improving work efficiency.
