Composite Machining
Drilling, countersinking and backing
Entry and exit forces can separate plies; backing, point geometry and controlled thrust reduce breakout and delamination.
In simple terms
Entry and exit forces can separate plies; backing, point geometry and controlled thrust reduce breakout and delamination.
Best for
Fastener holes, inserts and countersunk joints.
Watch out for
Progressive drilling is not universal; the approved sequence must preserve roundness and fibre support.
Typical applications
Bolted joints, sandwich hard points and repairs.
