Due　to　its　high　hardness　and　excellent　wear　resistance,　single　crystal　diamond　has　been　widely　applied　in　me-chanical　processing.　However,　the　outstanding　hardness　leads　to　great　difficulties　in　the　machining　of　diamond　by　traditional　strategies.　In　this　study,　a　synchronous　feed　laser　method　is　developed　to　realize　low　damage,　high　efficiency,　and　high　precision　machining　of　single　crystal　diamond　cutting　tools.　The　disadvantages　of　traditional　direct　laser　machining,　including　fullerene　residue,　bending　behavior,　and　the　plasma-shield　effect,　are　well　avoided　by　the　good　control　of　the　scanning　path　during　the　laser　fabrication,　which　enlarges　the　entrance　of　the　kerf　and　reduces　the　air　pressure　inside　the　kerf.　The　synchronous　feed　laser　machining　can　realize　the　remarkable　increase　of　kerf　depth　at　high　speed,　as　well　as　a　minimum　roughness　of-147　nm　on　the　cutting　surface.　It　provides　a　novel,　high　efficiency,　and　high　precision　strategy　for　the　preparation　of　high　quality　single　crystal　diamond　tools.
