The present invention provides a method for grinding a drill, because the first groove face and the second groove face with flat and broad can be formed with axial symmetry at the outside terminal, therefore the method can process this kind of processing operation easily and exactly, the present invention also provides a grinding apparatus using the method. A ruler piece (34) is mounted before a drill (28) fixed by a drill chuck, which can move fore-and-aft at a sloped straight-line (A3) with slope angle downward. A ruler surface of a level indicator (37) can be horizontal moving caused by movement of the ruler piece (34) at the front end of the ruler piece (34). The ruler piece (34) moves forward for setting parallel translation horizontal plane of the level indicator (37), thereby forming the station of top end pitch surface (5) and (6) incline against the surface of the level indicator (37). The incline against station forms downwards oblique station of generating line (A5) at the incline grinding face (31) of rotatingdisc abrasion wheel relative to the top end (1) and (2).The groove face (9) and (10) with bigger width (W) at the outside terminal is grinding at top end flank (3) and (4), when the drill chuck and the drill (28) are operation with the tilt state. |
