The utility model provides a cyclic annular little texture diamond coating blade structure, includes the blade body, and blade body surface is provided with the texture groove that a plurality of was evenly arranged according to the rectangular array, and is the degree of depth in texture groove 10 15 mu m, the width in texture groove is 0.1mm, does the area in texture groove account for 12 of blade surface area 15%, blade body surface and texture inslot wall all set up one deck diamond films. Little texturing on this surface through to the blade is handled, reaches the anti bond property's that improves the blade surface purpose, makes the blade not only have diamond coating's high rigidity when the cutting, and the good cutting process performance of high wearing feature still possesses and has the self -lubricating of little texture effect, the lubricated state of the friction of solution blade when the cutting that can be fine, and reduce friction prevents to bond, effectively reduces cutting force and cutting temperature, subtracts the mini blade wearing and tearing. Adopt the utility model discloses the diamond coating blade that the preparation was come out can extensively be used for difficult processing material's cutting process.
