| Popis: | In this study, selective laser sintering was used to 3D print resin bond diamond grinding wheels with internal cooling holes. The mechanical properties and microstructures of the resin bond diamond grinding wheel were investigated. The grinding performance of 3D printed resin bond diamond grinding wheels with different internal cooling holes on the glass and cemented tungsten carbide was examined. The results show that 3D printed resin bond diamond wheels can be used to grind the glass and cemented tungsten carbide. Wheels containing internal cooling holes have lower grinding force. With increasing number and diameter of internal cooling holes, grinding forces on the glass decreased. Surface roughness up to 2–4 μm on the glass and cemented carbide was obtained by present 3D printed resin bond diamond wheel. |
