The feeding spring collet of our factory single-axis automatic lathe has a long service life, the chuck is worn, and the elastic force is reduced, which will result in poor feeding. Sometimes the self-made spring collet is not tight due to its own quality problems, which affects the feeding. In this case, the column should be replaced or reworked. Now use a small circlip to extend the life of the collet.
