<p>The present invention relates to a device for grinding a gun drill to prevent the excessive grinding of many-sided cutting edges formed on the carbide part of a gun drill and to uniformly grind the cutting edges at predetermined angles during the grinding of the cutting edges. The device for grinding a gun drill comprises: a base; a grinding unit which has a grinding stone arranged at an angle corresponding to the angle of the cutting edges, is fixated to the base to correspond to the number of the cutting edges, and grinds the cutting edges using the grinding stone corresponding to the angle of the cutting edges; and a moving unit which is installed on the base to be moved in the installation direction of the grinding unit and which allows the grinding unit having the grinding stone corresponding to the relevant cutting edges to grind the cutting edges while chucking and moving the gun drill.</p> |
