When the radial drilling machine is working, if the drill bit falls off, stop the work in time, turn off the power supply, and then perform inspection and repair work to analyze the cause of the occurrence.

1. First, check whether the drill bit of the radial drill machine is seriously worn. The drill bit with severe wear is very difficult to drill. Not only can it not drill the required hole, but it will also cause damage to the machine tool. Therefore, it must be done before the workpiece is processed by the radial drill. Check the integrity of the drill bit. If the drill bit is severely worn, replace it in time.

2. Check whether the spiral groove on the drill bit of the radial drilling machine is blocked by chips and affect the normal use of the drill bit. If this is the case, clean it up in time.

3. When the radial drilling machine is about to drill to the end, reduce the feed amount in advance and change the motor feed to manual feed to prevent damage when the drill bit passes through the workpiece, which will also cause the drill bit to fall off.

4. When machining workpieces on a radial drilling machine, the material needs to be analyzed, because workpieces of different materials have different requirements for the drill bit. If it is a soft metal material, the drill bit must be ground before drilling it. use.

5. There is another aspect to pay attention to. Do not over-grind when grinding the drill. It is not that the sharper the drill is, the better, because the sharpness of the drill will cause the phenomenon of edge chipping during the drilling process. The speed can't keep up, so there will be edge chipping.
