According tothe drill bit grinding equipment disclosed by the invention, a miniature twist drill bit can be grinded and modified.

Description

technical field [0001] The invention relates to a grinding device, in particular to a drill bit grinding equipment for drilling motorcycle frames. Background technique [0002] If the cutting edge of the existing twist drill used for drilling motorcycle frames is worn out, for a twist drill with a larger diameter, the naked eye can clearly see the edge surface of the drill bit, and the drill can be directly visually viewed on the edge of the grinder by manually holding the drill bit. Grinding, or using special twist drill edge grinding equipment; for micro twist drills such as Φ1-2mm, the cutting edge surface is small and cannot be seen with the naked eye. Once wear occurs, manual grinding is difficult and can only be discarded. . Contents of the invention [0003] The object of the present invention is to provide a kind of drill bit grinding equipment for motorcycle frame drilling which can grind and repair the miniature twist drill bit. [0004] In order to achieve the...
