The　first　author　invented　a　unique　diamond-like　carbon　(DLC)　grinding　wheel,　in　which　the　DLC　fibres　were　made　by　rolling　Al　sheets　coated　with　DLC　films　and　aligned　normally　to　the　grinding　wheel　surface　by　laminating　Al　sheets　together　with　DLC　fibres　[K.　Yamaguchi,　Y.　Wei,　M.　Takeuchi,　Development　of　DLC　fibre　grinding　wheel,　in:　Proceedings　of　the　Vernal　Meeting　of　the　JSPE,　Tokyo,　16-18　March　1999,　p.　260].　In　this　paper,　the　formation　process　of　DLC　fibres　and　the　fabrication　process　of　a　DLC　fibre　wheel　were　investigated.　Many　grinding　experiments　were　also　carried　out　on　a　precision　NC　plane　milling　machine　using　a　newly　developed　DLC　wheel.　Grinding　of　specimens　of　silicon　wafers,　optical　glasses,　quartz,　granites　and　hardened　die-steel　SKD11　demonstrated　the　capabilities　to　nanometer　surface　finish.　A　smooth　surface　with　a　roughness　value　of　Ra　2.5　nm　(Ry　26　nm)　was　achieved.　(C)　2004　Elsevier　Inc.　All　rights　reserved.
