While heating, the metal gets soften and reaches the melting point. Proper lubrication is necessary to save the bit from adhering. The interesting point is that there is no loss of material but in a result, it forms a sleeve around the hole. Here the length of the sleeve can be three times more than the original thickness of the working material.
After forming a hole the process follows chip less thread formation. After the thread formation, one can check the thread by tightening the screw in the hole with proper torque and depth angle.
This process requires very high motor capacity and maximum rotational speed than other drills. Moreover, this process is not possible in the massive materials because the molten material requires space to flow.
Advantages of Friction Drilling
- The process is indeed very quick and simple (You can make a hole in just 2-6 seconds)
- There is no loss in the metal and it forms a sleeve which is three times more than the original thickness.
- Overall friction drilling is a clean and quick process to make holes.
- This process is applicable on every metal.
