A standard drill bit is a very common drilling tool. It has a simple structure and convenient sharpening, but it is not the same easy thing to really sharpen it well and master the methods and skills of sharpening. Whether the drill is easy to use or not mainly depends on the hardness of the material of the drill bit and the texture of the corresponding drilled object, that is, only when you have a diamond can you dare to do porcelain work. Of course, the sharpness of the drill blade is also very important. How to grind a CNC drill well? It depends on what you have. It is best to have an electric grinding wheel or something like that: 1. You need to observe the angle of the edge of the new drill. Artificial repair wear drill only needs to grind to that angle.

1. You need to observe the angle of the blade surface of the new drill bit. If you manually repair the worn drill bit, you only need to grind it to the sharp edge surface at that angle. If you grind it on an electric grinding wheel, you must pay attention to the instantaneous and multiple grinding.
2. Remember to soak in water and cool every time you grind, because the high temperature generated by grinding is enough to burn off the drill bit (the drill bit edge becomes black or brown).
3. Pay full attention to the rear angle of the drill bit and do not grind it too large or too small. When drilling with too large rear angle, the orifice is trilateral or pentagonal, the vibration is severe, and the chips are needle-shaped; when drilling, the axial force of the drill with too small rear angle is very large, it is not easy to cut into, and the drill is too hot to drill.
