According to the principle and characters of abrasive belt grinding, a special device has been designed which has been used in grinding process of long and thin shafts. The research objects are Dimensional precision and roundness error and focuses on change of abrasive belt grinding Dimensional precision and roundness after belt grinding. And the factors influencing belt grinding working accuracy are analyzed. The measures that increasing the belt grinding precision are pointed out. Research result shows that by installing a belt grinding device on a lathe to grind the slender shafts can improve the accuracy with high efficiency.
