Fabrication of metal-bonded grinding/polishing tools by the greentape laser sintering method

摘要

The present paper proposes a new methodology of fabricating metal-bonded grinding/polishing tools by the greentape laser sintering method. The porosity of copper sintered parts is utilised for manufacturing grinding/polishing tools containing cubic boron nitride (CBN) or alumina abrasives. The feasibility investigation shows that a mirror surface is achieved in polishing austenitic steel with a copper-bonded CBN tool.
