Diamond intermittent micro-grinding cutter

Abstract

A diamond intermittent micro-grinding cutter comprises a cutter handle section, a transition section and a cutter head section. The cutter handle section is of a cylindrical structure, the transitionsection is of a conical frustum structure, the cutter head section is of a polygonal cylindrical structure, the cutter handle section is located at the large-diameter end of the transition section, the cutter head section is located at the small-diameter end of the transition section, the cross section of the cutter head section is in a hexagonal shape and is divided into three arc edges and threelinear edges, and the first arc edge, the first linear edge, the second arc edge, the second linear edge, the third arc edge and the third linear edge are sequentially connected end to end. Diamond abrasive particles are electroplated on the surface of the transition section, diamond abrasive particles are electroplated on the portions, corresponding to the three arc edge, on the surface of the cutter head section, no diamond abrasive grain coating is arranged on the portions, corresponding to the three linear edges, of the surface of the cutter head section, no diamond abrasive grain coatingis arranged on the surface of the cutter handle section, the length of the first arc edge is larger than that of the second arc edge, the length of the second arc edge is larger than that of the third arc edge, circle centers of the three arc edges coincide, the linear lengths of the three linear edges are equal, and the thickness of the diamond abrasive grain coating is 0.03-0.06mm.

Description

technical field [0001] The invention belongs to the technical field of micro-grinding, in particular to a diamond intermittent micro-grinding tool. Background technique [0002] At present, in micro-precision machining, especially in the process of using traditional micro-grinding tools to process metal materials, due to the material characteristics of the metal material itself, the tool is easily blocked by chips, which deteriorates the processing environment and causes serious wear of the tool. It will affect the surface processing quality and further shorten the tool life. In addition, during the machining process, the large amount of grinding heat generated cannot be released well, which will cause thermal damage to the surface of the workpiece and the tool. Contents of the invention [0003] Aiming at the problems existing in the prior art, the invention provides a diamond intermittent micro-grinding tool, which has the characteristics of strong chip removal capabili...
