In　the　field　of　precision　machining,　with　the　popularity　of　brittle　and　hard　materials　such　as　infrared　windows,　has　become　difficult　for　conventional　diamond　grinding　wheels　to　effectively　perform　high-quality　machining.　The　structuring　of　traditional　diamond　grinding　wheels　using　a　pulsed　laser　is　a　key　technology　to　effectively　improve　the　grinding　quality　of　grinding　wheels.　In　this　paper,　three　new　shark　fin　diamond　grinding　wheels　(SFSGW)　with　different　slot　widths　are　designed　based　on　the　excellent　drag-reducing　and　channelizing　properties　of　shark　dorsal　fins.　The　grinding　performance　of　traditional　grinding　wheels　(USGW)　and　SFSGW　magnesium　fluoride　ceramics　was　compared.　The　effects　of　SFSGW　on　the　surface　quality,　surface　roughness　and　wheel　damage　of　the　workpiece　were　investigated.　The　results　showed　that　the　surface　roughness　of　ceramics　after　grinding　by　SFSGW　was　reduced　by　22.15　%　compared　with　USGW,　and　the　surface　quality　was　better.　Proper　construction　increases　the　material　removal　rate　of　the　wheel　and　improves　the　wear　resistance　and　service　life　of　the　wheel.
