Seven Factors and Their Solutions for Drilling Borehole Instability

The seven major factors and solutions for drilling borehole instability are as follows:

1: When the drill tip of the drill is worn or the spring is slack and weak. Should check the tapping tip for wear and cause uneven force, then check if the spring is too loose or a new spring.

2: The belt of the drill is not tightly adjusted or the belt is damaged and causes slippage. The drill belt V-belt is too loose. Adjust the adjusting screw on the back of the machine to the appropriate state or replace the belt.

3: The drill belt is too loose. Loosen the four small screws of the fixed drill and press the motor down, then tighten the four screws.

4: The clutch plate of the drilling machine has poor friction, and the clutch plate can be exchanged or the brake wheel can be replaced.

5: The microswitch of the drilling machine is broken, and a new microswitch is replaced.

6: The cam stop switch is not in the correct position. If the start is too slow, the operation of the drill will be unstable.

7: The material is deformed or there is too much residue in the chuck. More material should be inspected and the chuck should be cleaned.
