Firstly , it decrease the number of Ra ; Secondly , we improve the efficiency of manufacture . Because of saving the money and improve the quality of surface , the technique have its economy value ,and this attempt accumulate experiences on the reconstruction of traditional machines [Keywords]：Abrasive Belt Grinding ;The numerical control;Lathe
