Key Point on Machining
Cutting tool life is usually extremely short because of the high strength and abrasive properties
of carbon fibre, additionally delamination and burring easily occurs during cutting.
It is effective to use a PCD tool (sintered diamond) with high wear resistance. PCD drills reduce
burrs and delamination due to the PCD (sintered diamond) coating. In combination with an
optimized tool geometry, long tool life and high-quality machining can be achieved.
Application Example
PCD drills with optimized cutting geometry for composite materials reduces burr formation
and delamination.
