中文摘要：
根据砂带磨削的原理、特点、设计一台砂带磨削装置，并将其应用于细长轴的加工，实验中以尺寸精度和圆度误差为研究对象，重点研究砂带磨削后尺寸精度和圆度误差的变化，分析影响砂带磨削加工精度的因素，指出提高砂带磨削精度的措施。实验表明在车床上采用砂带磨削装置进行细长轴磨削，能有效地提高加工精度。
英文摘要：
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.
