A Small Add-on Makes a Big Difference!
In drilling processes where the Sine-Feed option is used, an axial spindle vibration is generated by means of a periodic low frequency. This, in combination with a constant spindle advance of the automated drilling unit, generates smaller chips which are easily removed. The result is a cleaner hole and outstanding chip removal.
What’s the impact of this small, incremental add-on?
- One shot drilling and countersinking
- Perfect hole surface quality
- Easily removed micro chips, even on piloted holes
- Dry cutting in Al/CFRP stacks is doable
- Durable: low heat evolution, particularly for thick stacks.
- Minimized impact of drill transition from a CFRP layer to titanium.
This totally focused mission on achieving the best possible outcome for customers like you is what sets Lübbering apart.
