Abstract:

An electroplated diamond wheel with detachable structure is designed to realize the green recy- cling and remanufacturing of diamond grinding wheels. The failure modes of abrasive layer are analyzed using the interface model of abrasive layer and wheel substrate. The stress states of abrasive layer are an- alyzed in the disassembling process of wheel, and the position of cracking point on the abrasive layer is determined. The electroplated diamond wheels with detachable structure were fabricated, and the separa- ting experiments of abrasive layer and substrate were carried out. The research results show that the inter- face crack or kinking crack occurs between abrasive layer and substrate nearby the slide during disassem- bling, resulting in the fracture of abrasive layer. The wheel cylindrical surface assembled with semicircu- lar slide blocks shows better smoothness. The symmetrical concave structure of slide block can improve the utilization rate of wheel. The green separation of abrasive layer from substrate and the remanufacturing of diamond grinding wheels can be realized for the electroplated diamond wheel.
