The solution of bit falling off in radial drilling machine

The solution of bit falling off in radial drilling machine

During the working process of radial drilling machine, when the drill bit falls off, it is necessary to stop working in time, turn off the power supply, and then do the inspection and repair work to analyze the causes.

1. First of all, it is necessary to check whether the drill bit of the radial drilling machine is seriously worn. It is very hard for the seriously worn drill bit to drill, which not only can not drill the required hole, but also causes damage to the machine tool. Therefore, before the radial drilling machine processes the workpiece, it is necessary to check the integrity of the drill bit. If the drill bit is seriously worn, it should be replaced in time.

2. Check whether the spiral groove on the radial drilling machine bit is blocked by chips, which affects the normal use of the bit. If so, clean it thoroughly in time.

3. When the radial drilling machine is about to drill to the bottom, it is necessary to reduce the feed rate in advance, and replace the motor feed with manual feed, so as to prevent the bit from being damaged when it passes through the workpiece, which will also cause the bit to fall off.

4. In the radial drilling machine for workpiece processing, it is necessary to analyze the material, because the requirements of different materials for the drill are different. If it is soft metal material, the drill should be polished before drilling.

5. Finally, there is another aspect to pay attention to. When grinding the drill bit, do not over grind it. The sharper the drill bit, the better. Because the drill bit is too sharp, it will cause the phenomenon of edge collapse in the process of drilling. Because the tool retraction speed can not keep up at this time, it will cause the phenomenon of edge collapse.
