Flowdrill CNC data consists of the technical machining data required to correctly program a Flowdrill frictiondrill tool on a CNC machine. The data helps determine the correct settings for the specific combination of tool, material and wall thickness.
During frictiondrilling, frictional heat locally heats the material, after which the material is displaced. This creates additional material thickness that can be used for a strong threaded connection. Because the process works differently from conventional drilling, the correct RPM and feed rates are important.
Flowdrill CNC data helps you set up the process correctly and achieve consistent results.

The data you need depends on your specific application. By providing the key details of your application, Flowdrill can determine which information and parameters are relevant.
Depending on the application, the CNC data may include:
The correct combination of this data ensures that the frictiondrill process matches your material, tool and CNC machine.

For friction drilling and tapping an M8 thread in mild steel (2 mm wall thickness), a Flowdrill tool running at 2180 RPM with programmed feed stages completes the cycle in 2.9 seconds.

The correct Flowdrill parameters are important for a stable frictiondrill process and consistent connection quality. An incorrect setting for RPM or feed rate, for example, can affect the machining result and the service life of the Flowdrill tool.
By matching the CNC parameters to the material, wall thickness and diameter of the Flowdrill tool, you can carry out the process in a controlled way.
