Abstract: To improve the accuracy preservation of three-jaw chuck, the effect of the abrasion of chuck components on its centering accuracy was investigated. The model of centering accuracy and repeatability of three-jaw chuck was developed. Results show that among the position errors of jaws induced by abrasion of chuck components, the radial position error dominates. For the wedge type power chuck, the repeatability accuracy is equal to the interval between chuck body and wedge plunger. Only when the interval between chuck body and wedge plunger is limited within the double systematic error of the centering accuracy, the method of turning top jaw can renovate the centering accuracy after long-term use of the chuck. But the accuracy inefficacy caused by the enlargement of the interval between chuck body and wedge plunger due to the abrasion cannot be renovated by turning the top jaw.

Key words: machine tool, three-jaw chuck, centering accuracy, abrasion, turning of top jaw
