Common problems and countermeasures:
1. The drill bit is broken, deformed or slipped. (Improve the rigidity of machine tools and tools, and increase the rigidity of workpieces and fixtures)
2. The back angle is too small. (Re-sharpening correction)
3.Cutting clogged. (Adjustment processing method: feed rate adjustment, using stepped stepwise)
4. The drill bit is worn. (Re-sharpening)
5. Poor knife-eating. (Increase the rigidity of tools, machine tools, workpieces, fixtures, etc., and check the level of the pre-machined surface)
6. The precision of the drill bit clamping is not good. The sintered drill bit and the spindle itself jump too much. (Calibrate the spindle, carefully measure and adjust each time the drill bit is clamped)
