【Abstract】 Conical grinding is widely used in drill point sharpening. Many advanced drill points are based on the conical flank face point, and the conical face is usually produced by rotating wheel or drill. The construction of these sharpening machines is complex, and they are difficult to adjust and control. Using cup wheel′s internal cone to form the conical flank face can simplify the machine structure, make adjustment easy and get more efficiency. In the paper, based on the conical grinding principle, the equations for structure parameters of the non straight lip drills are presented. The relations between the grinding parameters and drill structure parameters are studied. With an example, the principle and design method of cup wheel grinding are given, and the means to grind a drill specification is also shown. The results show that selecting a reasonable cup wheel can satisfy many specified drill geometry grinding, and just in some cases such as grinding a point with bigger clearance angle, bigger drill point angle and smaller chisel edge angle, this method would produce larger errors.更多还原
