Abstract: In order to achieve the grindability of superabrasive grinding wheel, a new kind of the superabrasive grinding wheel for end-grinding, which has defined abrasive grain cluster pattern, has been designed based on the phyllotaxis theory of biology. The influence of the phyllotactic parameters of the superabrasive grinding wheel on the abrasive arrangement configuration is analyzed, and the super abrasive grinding wheel is fabricated using ultraviolet lithography method and electroplating technology. The results of mill-grinding experiment show that the mill-grinding performance of the grinding wheel can be improved by selecting the reasonable phyllotactic coefficient k and abrasive grain cluster radius r.
