Thermal Friction Drilling System

For professionals who look for the highest quality in their products, the Flowdrill system provides a cost saving and problem solving production method for the formation of bushes in malleable metals. The Flowdrill thermal friction drilling produces perfectly formed bushes by using speed of rotation and pressure which heat the material locally, plasticize and form bush in various thickness of metals. When the Flowdrill comes into contact with the material using relatively higher axial pressure and RPM, frictional heat is created, allowing penetration and reforming the displaced material. It is a cost effective replacement for weld nut, rivet nut and press nut.

Advantages:

• Consistently accurate bush size
• Bush length is approx. 3 times the original thickness of the metal
• Cycle time is 2 to 6 seconds depending on the diameter and thickness of material
• The bushes formed are suitable for tapping with high pull out strength and torque loading
• Ideal for sleeve bearing and as a location for brazed connection
