What to do if the three-jaw chuck is worn for a long time?

The three-jaw chuck is one of the commonly used hydraulic accessories for lathes, but it often occurs after a period of use that the workpiece is not easily mounted. On the one hand, the jaws of the three-jaw chuck are unevenly worn in front of one another, and on the other hand, Due to improper use of the lathe, the jaws of the three-jaw chuck were partially damaged. With the wear of the chuck, the three claws will appear bell-shaped, and the three claws will slowly deviate from the center of the lathe spindle, which will increase the tolerance of the machined parts.

One of the easiest and most effective ways to solve the problem of three-jaw chuck wear is to process the outer diameter of the chuck dial with a matching outer circle, then use the sleeve to clamp the outside of the jaws, and then pull the jaws outwards to tension. Then use a file to correct the jaw's working surface.

Reducing the wear and tear on the three-jaw chuck not only effectively protects production safety, but also increases production efficiency, resulting in more economic benefits.
