In　order　to　enhance　the　grinding　performance　of　alumina　ceramic　materials,　the　surface　of　the　grinding　wheels　is　ablated　by　laser　radiation　before　grinding,　and　the　three　types　of　leaf-vein　bionic　grinding　wheels　with　different　micro-groove　pitches　are　formed　to　compare　the　grinding　experiments　with　normal　grinding　wheels.　The　grinding　forces　and　surface　roughness　were　gauged　and　the　morphological　characteristics　of　ground　workpiece　surfaces　were　studied.　The　results　showed　that　with　the　increase　of　groove　pitch,　the　normal　grinding　force　was　reduced　by　9.6-63%,　while　the　tangential　grinding　force　is　reduced　by　8.3-42%.　The　groove　can　promote　the　flow　of　coolant,　accelerate　the　heat　dissipation　and　chip　removal　in　the　grinding　area　and　reduce　the　damage　of　the　workpiece　and　the　wear　of　the　grinding　wheel,　so　the　vein　bionic　grinding　wheel　had　more　tremendous　processing　advantages.　Among　the　four　kinds　of　grinding　wheels,　the　leaf-vein　bionic　grinding　wheel　with　groove　pitch　equal　to　8　mm　obtained　the　best　grinding　effect.　The　vein-shaped　groove　had　a　positive　impact　on　the　grinding　process.
