[0035] A through hole 4 is formed in the middle of the lapping table 1, and the through hole 4 is used to keep the driving block 5 able to move up and down normally, pushing the lapping box 2 at the edge of the through hole 4. After the pushing is completed, the driving member 6 drives the driving block 5 to reset downward, and the lapping box 2 is reset to the middle of the through hole 4 under the elastic force of the spring 7 and the elastic member 8, thereby keeping the lapping box 2 in an active state, so that the steel balls in the lapping box 2 are in a rolling state, and the steel balls are lapped so that the surface of the steel balls is polished to a bright finish.

[0036] A driving member 6 is provided at the lower end of the through hole 4 , and a driving block 5 is provided on the driving member 6 . The driving member 6 pushes the driving block 5 to move up and down in the through hole 4 .
